Meningioma arises from the arachnoid cap cells of the cerebrum. Intraparenchymal meningiomas or meningiomas without dural attachment are rare. We report a case of 40-year-old male who presented with a history of headache, dizziness and gradual loss of vision since one year. Clinicoradiological diagnosis of a high grade glioma was considered. Tumour was excised and haematoxylin and eosin stained sections revealed a tumour comprised predominantly of variable sized blood vessels showing hyalinization in a background of plump spindle cells with oval vesicular nuclei. In view of these features angiomatous meningioma was suspected. However, to confirm the diagnosis, a panel of immunohistochemical markers including vimentin, EMA and GFAP was done and a final diagnosis of angiomatous meningioma was offered. Angiomatous meningioma is a rare variant of meningioma and even much rarer in the intraparenchymal location. Angiomatous meningioma should be considered in the differential diagnosis of highly vascular intraparenchymal brain tumours.
