Most primary intradural spinal arachnoid cysts are dorsal to the cord. They occur at the following locations: Secondary spinal arachnoid cysts can be located anywhere, depending on where the insult has occurred (see "Etiology" above). On CT myelography, the compressed cord is displaced anteriorly 3.
For intradural arachnoid cysts, several alternative diagnoses should be considered: bright on DWI (as in the brain, spinal epidermoids are differentiated from arachnoid cysts by their brightness on DWI) Rarely, extradural cysts may be considered, although they are generally clearly not within the dura. They include: 1.

Arachnoid cysts are cerebrospinal fluid-filled sacs that are located between the brain or spinal cord and the arachnoid membrane, one of the three membranes that cover the brain and spinal cord.
An arachnoid cyst is a noncancerous fluid-filled sac that grows on the brain or spinal cord. Symptoms include headaches and seizures, but many arachnoid cysts don't cause symptoms. Treatment isn't always necessary. Providers drain or remove cysts that cause symptoms.
A brain cyst or cystic brain lesion is a fluid-filled sac in the brain. They can be noncancer (benign) or cancer (malignant). Benign means that the growth doesn't spread to other parts of the body. A cyst may contain blood, pus, or other material. In the brain, cysts sometimes contain cerebrospinal fluid (CSF).

According to ICD-10-CM Official Guidelines for Coding and Reporting FY 2018, “unspecified codes are to be used when the information in the medical record is insufficient to assign a more specific code.” In my opinion, this can be the case with testing, when lab work or cultures do not support the more specific code.
Unspecified is reserved for etiological ambiguity or conditions that don't line up with anything in a particular diagnostic category.
Arachnoid cysts are usually intracranial and supratentorial in location, but spinal, and even intraneural, cysts may be identified and possibly cause symptoms. Asymptomatic cysts do not require active management. However, some are associated with seizures, local pressure effects, or hydrocephalus and may require treatment. Urine should be checked for glutaric acid in cases of bitemporal arachnoid cysts as glutaric aciduria type 1 is present in 25% of cases. Symptomatic cysts will require intervention in the presence of hydrocephalus or spinal cord compression. Surgical intervention to treat seizures or headache is successful in only 33% to 50% of cases. Electroencephalographic seizure focus coinciding with temporal arachnoid cyst and SPECT imaging demonstrating impaired cerebral perfusion may be helpful when considering intervention. Minimally invasive neuroendoscopic techniques are being more widely practiced where there is hydrocephalus or suprasellar cysts, but resection and marsupialization for large Sylvian fissure and cortical arachnoid cysts has superior success rates to neuroendoscopic procedures. Endoscopic fenestration, although less effective at reducing cyst size, has a lower complication rate. The complication rate of fenestration of arachnoid cysts in pediatric cases is over 35%. About 10% of arachnoid cysts recur after fenestration, and subdural hygromas requiring re-operation occur in 6% of all cases of large Sylvian fissure arachnoid cysts.
Arachnoid cysts are classified as developmental cysts; they were first described in 1831 ( 10 ). These cysts lie between 2 membranes of normal arachnoid matter and are more properly described as intra-arachnoid cysts ( 101 ). Congenital or developmental arachnoid cysts differ from secondary or acquired arachnoid cysts, as the latter are loculations of CSF surrounded by arachnoid scarring. A classification of midline cysts based on neuroembryologic analysis and imaging, suggests 2 categories:
Most primary intradural spinal arachnoid cysts are dorsal to the cord. They occur at the following locations: Secondary spinal arachnoid cysts can be located anywhere, depending on where the insult has occurred (see "Etiology" above).
As with any arachnoid cyst, spinal arachnoid cysts are CSF -filled sacs contained by the arachnoid mater. The degree of communication with the surrounding CSF space is variable with some cysts freely communicating and others not at all 9 .
Etiology. They may be congenital or acquired. Secondary arachnoid cysts are usually due to trauma, hemorrhage, inflammation, surgery or iatrogenic injury like lumbar puncture, injection of anesthetic or contrast material within the subarachnoid space 3,4,13.
Treatment and prognosis. Incidental asymptomatic cysts are managed conservatively. Symptomatic cysts can be treated with surgical excision . An important component of surgical treatment of epidural cysts includes closure of the arachnoid defect, if any, which could become a source of CSF leak.
spinal dermoid cyst. most common location is the lumbar spine. imaging characteristics are variable but usually resemble fat 3. spinal endodermal cyst: common in the lower cervical and upper dorsal spine ventrally. usually Indistinguishable from an arachnoid cyst on imaging 12. spinal hydatid cyst.
Most arachnoid cysts eventually opacify with contrast, although the rate at which they do so is variable 7,9. In many instances, the cyst opacifies readily and as such, it may be challenging to diagnose with certainty.
Typical symptoms of an arachnoid cyst around the brain include headache, nausea and vomiting, seizures, hearing and visual disturbances, vertigo, and difficulties with balance and walking. Arachnoid cysts around the spinal cord compress the spinal cord or nerve roots and cause symptoms such as progressive back and leg pain ...
The location and size of the cyst determine the symptoms and when those symptoms begin. Most individuals with arachnoid cysts develop symptoms before the age of 20 , and especially during the first year of life, but some people with arachnoid cysts never have symptoms.
Primary arachnoid cysts are present at birth and are the result of developmental abnormalities in the brain and spinal cord that arise during the early weeks of gestation. Secondary arachnoid cysts are not as common as primary cysts and develop as a result of head injury, meningitis, or tumors, or as a complication of brain surgery.
In the past, doctors placed shunts in the cyst to drain its fluid.
Untreated, arachnoid cysts may cause permanent severe neurological damage when progressive expansion of the cyst (s) or bleeding into the cyst injures the brain or spinal cord. Symptoms usually resolve or improve with treatment.
324.9 is a legacy non-billable code used to specify a medical diagnosis of intracranial and intraspinal abscess of unspecified site. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
