Subdural fluid accumulation with two meningiomas in a cat

Abstract

A case of two separate meningiomas with concurrent subdural fluid accumulation is presented. A 13‐year‐old, male neutered domestic shorthair cat presented with behavior change and progressive neurologic signs localizing to the forebrain. Two extra‐axial masses were seen along with a large subdural fluid collection on advanced imaging of the brain. Histology of the lesions was consistent with multiple meningiomas, while analysis of the subdural fluid was consistent with cerebrospinal fluid. A case of multiple feline meningiomas with peritumoral subdural fluid accumulation has not previously been reported.
