Can a macroadenoma cause chiasm compression?

Optic chiasm compression. A macroadenoma growing superiorly out of the pituitary fossa (or for that matter other pituitary region masses) will contact, elevate and compress the central part of the chiasm in most individuals. This central part carries fibers from the nasal retina, and thus results in the classical bitemporal hemianopia 10.

What happens when the optic chiasm is damaged?

Damage to the retina or one of the optic nerves before it reaches the chiasm results in a loss of vision that is limited to the eye of origin. In contrast, damage in the region of the optic chiasm—or more centrally—results in specific types of deficits that involve the visual fields of both eyes (Figure 12.8).

What is Macroadenoma pituitary gland?

A macroadenoma is a usually benign tumor composed of glandular tissue growth larger than 10 mm (those under 10 mm are called microadenomas) in the pituitary gland. The term macro simply refers to its size. Macroadenomas can cause symptoms because they grow and press on nearby brain structures.

What is Microadenoma pituitary gland?

A microadenoma is a very small, noncancerous tumor that typically develops in the pituitary gland – a pea-sized organ behind the eyes that regulates growth, development, metabolism and reproduction. There are two kinds of microadenomas: functioning (which produce hormones) and nonfunctioning (which do not).

What is an adenoma on the pituitary gland?

Pituitary adenomas are benign tumors of the pituitary gland. Most are located in the anterior lobe (front portion) of the gland. About 1 in 10 people will develop a pituitary adenoma in their lifetime. Some pituitary adenomas secrete one or more hormones in excess.

What is a neoplasm without metastatic potential?

A neoplasm without metastatic potential arising from the anterior or the posterior lobe of the pituitary gland. The vast majority are adenomas.

What are the complications of a pituitary adenoma?

The dreaded complication of pituitary adenoma, and one with which the ophthalmologist must be familiar, is pituitary apoplexy. This life-threatening complication results from acute hemorrhage or infarction of the tumor. Reported incidence varies between 0.6% and 10% of all pituitary adenomas [3]. Although trauma, blood pressure changes, and pregnancy can be predisposing factors, most cases occur spontaneously [4]. Presenting systemic features include severe headache, nausea, and altered mental status. Visual symptoms and signs include vision loss, diplopia, and multiple cranial nerve palsies secondary to rapid expansion of the tumor into the adjacent cavernous sinuses, with cranial nerve III the most commonly affected. Subarachnoid expansion of blood may lead to vasospasm and stroke. Acute endocrine abnormalities, including adrenal crisis and accompanying severe hypotension, can be fatal if not recognized and treated. Treatment is emergent and includes corticosteroids, surgical resection, and supportive measures.

What is the radiographic evidence for pituitary apoplexy?

Radiographic findings in pituitary apoplexy may include hyperdensity of the adenoma on CT (Figure 5) , combined with relatively mild, patchy contrast enhancement of the tumor on MRI (Figure 6). This is due to hemorrhage-induced expansion and necrosis of the tumor, leading to non-perfusion. Layering hemorrhage in the lateral ventricles can also be seen (Figure 7), which can result in a communicating hydrocephalus.

What is the arrow in the T1 brain MRI?

What is the difference between a nonsecretory tumor and a secretory tumor?

Classically, the nonsecretory tumor presents with vision loss, whereas patients with secretory tumors are usually referred to ophthalmologists for evaluation after having already been diagnosed because of endocrine derangements.

Is parasellar meningioma a snowman?

A parasellar meningioma is a potential mimic of the pituitary adenoma, but has a comparatively harder texture, preventing it from compressing at the diaphragma sella, and therefore no “snowman” appearance. Pituitary adenoma is the most common cause of the chiasmal syndrome [2], and may present at any age.

Can sarcoidosis cause chiasmal syndrome?

Rarely, sarcoidosis, multiple sclerosis, chiasmal contusion from frontal trauma, and cerebral masses can cause a chiasmal syndrome, mimicking the visual field loss seen in pituitary adenoma.

Is cranial adenoma heterogeneous?

Craniopharyngioma is notable for its heterogenous radiographic appearance, often containing cysts and calcifications, which are best viewed on computed tomography (CT). The pituitary adenoma typically lacks these features, though heterogeneity may be present if hemorrhage has occurred.

What is differential of pituitary macroadenoma?

The differential of a pituitary macroadenoma is essentially the list of conditions leading to a pituitary region mass. The most common considerations include: pituitary metastasis. often in the setting of known disseminated malignancy. often less well defined. bone destruction rather than remodeling may be seen.

What is the clinical presentation of optic chiasm?

Clinical presentation. Patients typically present with symptoms of local mass effect on adjacent structures (especially optic chiasm ). Some may present due to hormonal imbalance, with symptoms of hypopituitarism (from compression) or secretion.

What is the most common suprasellar mass in adults?

Pituitary macroadenomas are the most common suprasellar mass in adults, and responsible for the majority of transsphenoidal hypophysectomies. They are defined as pituitary adenomas greater than 10 mm in size and are approximately twice as common as pituitary microadenomas .

What happens when macroadenoma grows asymmetrically?

In cases of prefixed or postfixed chiasms, or when the macroadenoma grows asymmetrically, then the optic nerves or optic tracts can be compressed, resulting in a variety of visual deficits.

Where do macroadenomas come from?

Pituitary macroadenomas are by definition >10 mm diameter masses arising from the pituitary gland, and usually extending superiorly into the suprasellar cistern where it can compress the chiasm. Bilateral indentation by the diaphragma sellae as the tumor passes superiorly can give a snowman or figure-eight configuration 10 .

Where is the optic chiasm located?

The optic chiasm is located directly over the pituitary gland in 80% of individuals. The rest is divided between pre and postfixed chiasms. A prefixed optic chiasm is located anterior to its normal position over the tuberculum sellae, whereas a postfixed chiasm is located over the dorsum sellae 10 .

Why is the pituitary fossa enlarged?

Because these tumors are typically slow-growing, the pituitary fossa is almost invariably enlarged with thinned remodeled bone.

What is the classification of pituitary tumors?

Previously, pituitary tumors were classified by their hormone content and structural features. Currently, rather than classifying a tumor as “hormone-producing” or “functional” adenoma, pituitary tumors are defined by their cell lineage and are further divided based on immunohistological stains and tumor markers.

How to treat pituitary adenomas?

Goals of treatment include visual recovery/preservation, reversal of hypersecretory syndromes, and control of tumor growth. While some forms of pituitary adenoma can be managed medically, most pituitary adenomas that have demonstrable visual field loss are treated surgically. Radiation therapy (external beam or gamma-knife) is considered a second-line treatment.

What are the most common clinically functional adenomas?

Lactotroph adenomas arise from Pit-1 lineage and mainly express prolactin (PRL) and estrogen receptor α (ERα). They make up 30-50% of pituitary adenomas and are the most common clinically functional adenomas. In men, the size of the adenoma is more likely to cause compressive symptoms while in women, there are more hormone imbalances. High prolactin levels cause amenorrhea, galactorrhea, and infertility in women, and hypogonadism and impotence in men. In the setting of a prolactin secreting tumor, galactorrhea-amenorrhea is termed Forbes-Albright syndrome. Modest elevations in prolactin however can occur without prolactin secreting tumor because of the effect of compression of the stalk (removing the inhibition from dopamine) and is called the stalk effect.

Why does adenoma grow?

The adenoma grows precipitously because of the removal of the feedback inhibition of adrenal corticosteroids on the pituitary tissue. Hypercortisolism is not present because of the absence of the adrenal glands. Patients will complain of symptoms consistent with the mass effects of a pituitary tumor.

What is the cytoplasm of adenomas?

Adenoma cells stain on immunohistochemistry based on the type of hormone they secrete. The cytoplasm of these cells may be acidophilic, basophilic, or chromophobic, and is generally uniform in its appearance.

What is the procedure for debulking a pituitary adenoma?

Pituitary adenoma debulking, or partial excision, is often carried out via transfrontal, transsphenoidal, or transpterional approaches. Endoscopic techniques have improved visualization of the tumor and allowed for smaller incisions and faster healing.

What is a microadenomas on a T1 scan?

They are seen as hypointense areas within the substance of the relatively hyperintense pituitary gland . With gadolinium contrast these lesions will remain less intense compared to the normal gland and will enhance late. On T2-weighted images, the adenoma is more indistinct, as it appears isointense or only slightly hyperintense in comparison with the surrounding gland.

What is pituitary macroadenomas?

Pituitary macroadenomas are defined as sellar mass lesions with a diameter greater than 10 mm ( Hardy, 1969 ). They can be reliably visualized with routine MR imaging and thus, the task is rather to describe precisely the extent, location, structure, and relation to the surrounding anatomic structures; this helps with the differential diagnosis. It is characteristic for pituitary adenomas that the bulk of the lesion is located within the sella. The tumors may be inhomogenous, since regressive changes may be present ( Fig. 11.4 ). Mostly the extension is superior, into the opticochiasmatic cistern, and may reach up to the foramen of Monro, producing hydrocephalus. The amount of compression and deformation of the optic chiasm is best appreciated on the coronal sections. With increasing suprasellar tumor size the chiasm is increasingly displaced, becomes more and more flattened, and, in some huge adenomas with grotesque suprasellar extension, the visual pathways may escape direct depiction. There may be tumor extension downwards, into the sphenoid sinus, with expansion of the sella or even perforation of the sellar floor which is indicative of invasion. Lateral tumor expansion is also frequent and often the question arises if the tumor is still encased or exhibits an invasive growth pattern ( Ahmadi et al., 1986 ). Only total encasement of the carotid artery, with tumor clearly visible lateral of the vessel, proves invasion beyond doubt. Even grotesque lateral extension sometimes turns out not to have resulted in invasion. A line drawn between the sectioned portions of the intracavernous carotid artery frequently helps to make the distinction ( Knosp et al., 1993 ). In several instances, imaging with very high field strength (3 T) offers the possibility of direct depiction of the invasion site, which is usually not possible with 1.5 T images ( Wolfsberger et al., 2004; Yoneoka et al., 2008; Linn et al., 2011 ). Normally, a compression, flattening and distortion of the normal pituitary gland can be seen, preferably to the posterior or lateral periphery of the tumor. This is particularly well shown on contrast-enhanced images, on which the pituitary gland enhances more quickly and appears much brighter than the adenoma. An easier distinction is made if there is only unilateral parasellar extension of the adenoma. Pituitary adenomas are virtually never invasive into the very cavernous sinus that is covered by a thin layer of compressed and displaced pituitary, and consistently have their major parasellar extension on the contralateral side of the location of the deformed residual normal gland ( Buchfelder and Schlaffer, 2010 ). Pituitary surgeons regularly appreciate this growth pattern to identify and protect normal gland tissue. Recently, the signal intensity of growth hormone-secreting pituitary adenomas in T2-weighted images was used to predict the response of the tumors and their secretion to somatostatin analogs. Heck et al. (2012) demonstrated much better treatment effects in hypointense tumors in contrast to hyperintense ones. They relate the different response to the ultrastructure of the tumors which is revealed by their presentation on MRI. All sparsely granulated adenomas exhibited a hyperintense signal in T2-weighted images. However, there were also isointense tumors which did not allow reliable prediction.

What percentage of neoplasms are mcroadenomas?

Macroadenomas are among the most common of all CNS neoplasms, accounting for 10-15% of primary intracranial neoplasms.

What is a macroadenoma in FLAIR MR?

Coronal FLAIR MR shows an example of a macroadenoma that elevates and compresses the optic chiasm. Gonadotroph adenomas are usually macroadenomas at the time of presentation.

What is the T1W in Fig. 7?

Fig. 7. Sagittal (A) and coronal (B) T1W noncontrast images showing hemorrhage into an existing pituitary macroadenoma. The area of high T1 signal represents the recent hemorrhage. There is a component of the tumor extending into the left cavernous sinus which does not show hemorrhage. The suprasellar extension is compressing the chiasm particularly on the right side.

What is a nonfunctioning macroadenomas?

Nonfunctioning macroadenomas (NFMAs) are pituitary tumors without systemic hormonal hypersecretion. Several authors reported that patients with resected NFMAs have sleep complaints and circadian alterations as well as objective PSG or actigraphy changes.23 In one study, patients with NFMAs had reduced sleep efficiency, less REM sleep, more N1 sleep, and more awakenings in the absence of associated apneas or periodic limb movements (compared with controls). Actigraphy revealed longer rest durations, more awakenings at night, and less activity during the day. Patients with treated NFMAs reported more fatigue and impaired QoL. 23 In another study, Joustra and colleagues 24 found melatonin secretion abnormalities in a significant percentage of patients with NFMAs and pituitary craniopharyngiomas, likely owing to either suprachiasmatic clock abnormalities induced by suprasellar extension or the treatment instituted for the pituitary tumor. Patients with NFMAs have also been found to have increased risk for developing metabolic syndrome (reduced high-density lipoprotein cholesterol and increased triglycerides) 25; interestingly, identified factors were preoperative visual field defects and hypopituitarism. This association may be explained by hypothalamic dysfunction leading to the well-known hypothalamic obesity, 26 intrinsic imperfections of hormone replacement therapy, 25 direct effect of associated sleep disturbances, 27 or other, unidentified causes.

What is the IHC for a gonadotroph adenomas?

Gonadotroph adenomas by definition express IHC (+) for FSH &/or LH; in the absence of immunostaining for these specific anterior pituitary hormones, presence of the relevant transcription factor (SF1) also serves to define gonadotroph adenomas.

How long does it take for a pituitary to regress?

After pituitary surgery it takes around 3–4 months for the postoperative changes within the sella to regress to allow for assessment of the true volume of residual pituitary tissue ( Kremer et al., 2002 ).

What is the code for a primary malignant neoplasm?
