Calcifying Pseudoneoplasm Of The Cerebellomedullary Cistern: A Case Report And Review Of The Literature

Sir, Calcifying pseudoneoplasms (CPNs) are rare, calcified, non‐neoplastic lesions and can occur in any part of the central nervous system (CNS). They were first described by Rhodes and Davis.[1] In the pathophysiology, although there is not a complete consensus among authors, they are thought to occur after a reactive or metaplastic process in the neuraxis. Our patient is the first reported case in this anatomic location and second time reported case of CPN with its imaging features in the literature.
