A case of intradural extramedullary
cavernous angioma is presented with
headache,
dizziness, and bilateral
sensorineural hearing loss caused by an intracranial superficial
hemosiderosis. It was incidentally found in a
patient with a 3-month
history of sustained
headache,
dizziness and a 3-year
history of
hearing difficulty. The
neurological examination was unremarkable in the
lower extremity. MR images showed an intracranial superficial
hemosiderosis mostly in the cerebellar region.
Myelography and MR images of the thoracolumbar
spine revealed an intradural extramedullary mass, which was pathologically proven to be a
cavernous angioma. T12 total laminoplastic
laminotomy and total
tumor removal were performed without any
neurologic deficits. The
patient's symptoms, including
headache and
dizziness, have been absent for three years. Intradural extramedullary
cavernous angioma can present with an intracranial superficial
hemosiderosis as a result of chronic
subarachnoid hemorrhage.
