Calcifying pseudoneoplasm of neuraxis (CAPNON) is a rare but distinctive lesion of the central nervous system. These are benign lesions that mimic ossified vascular lesions clinically and radiologically, and can be cured by complete resection. We report a case in a 48 year old male with complex partial seizures who had a right temporobasal calcified lesion that clinically and radiologically mimicked an oligodendroglioma. Histopathology revealed a large necrotic lobulated mass with admixture of chondromyxoid zones, nodular fibrovascular stroma, metaplastic calcification and ossification in varying proportions.
