Abstract
We hereby report an extremely unusual case of cystic angiomatous
meningioma in the CPA region in a 58-year-old male patient. He
presented with complaints of headache, repeated episodes of vomiting
and increasing unsteadiness of gait. Neuroimaging showed a large
multicystic left-sided tentorial tumor projecting into the cerebellum
and CPA with contrast-enhancing peripheral solid rim. He underwent a
left retromastoid craniectomy and total excision of the tumor.
Histopathology revealed an angiomatous meningioma with predominant
microvascular component and extensive cystic changes. Immunopositivity
for epithelial membrane antigen (EMA), vimentin and S-100 protein
proved vital in excluding a hemangioblastoma
