Dr Rashida Nalwala

Abstract: Psammomatous meningioma is a rare histologic subtype of meningioma with an incidence of 3.8 % compared to the other more common histologic subtypes, meningothelial followed by fibrous and transitional meningiomas, which account for approximately 80 % of all meningiomas. Also the psammomatous subtype is more common in the spine compared to the intracranial location. Here we present a case of a 40 year old female with psammomatous histological subtype of WHO grade I meningioma, located in the olfactory groove presenting to the outpatient department with headache and mild cognitive decline.
