Clear Cell Meningioma with Tyrosine Crystals: a Case Report with Review of Literature.

Abstract

Introduction or background: Clear cell meningioma is a rare WHO grade 2 tumour and runs an aggressive course. Tyrosine crystals are very uncommon in meningioma.

Case presentation: We present a case of a 43-year female with right middle and posterior cranial fossa space occupying lesion (SOL) diagnosed as clear cell meningioma with presence of numerous tyrosine crystals.

Discussion and conclusion: Whether these crystals are incidentally noted or if there is an actual relationship of these crystals with tumour environment must be found as they are seen in many other conditions too.
