8E40.Z/G90-G99 Disorders of the meninges excluding infection, unspecified



Disorders of the meninges can arise from a variety of sources and can be caused by congenital disorders, trauma, metabolic or systemic diseases, or tumor growth.


Diagnosis of disorders of the meninges is typically done through imaging studies including MRI and CT scans, lumbar puncture, and EEG. Depending on the type of disorder, other tests may also be necessary to confirm the diagnosis.

Differential diagnosis

Differential diagnosis of meningeal disorders includes conditions such as meningiomas, encephalitis, subarachnoid hemorrhage, and hydrocephalus.


Treatment for meningeal disorders depends on the underlying cause and may include surgery, radiation therapy, medications, and physical therapy.


The prognosis for disorders of the meninges is typically good with proper treatment. However, some conditions may require lifelong management.
