Abstract:
Vasculitis is characterized by inflammation of the vessel walls, with or without necrosis, that causes narrowing and occasionally obstruction of the vessels. Vasculitis can be a primary process or it can occur secondary to other disease. Isolated central nervous system vasculitis (ICNSV) is a rare type of primary vasculitis that predominately affects the supratentorial regions. The clinical presentation and imaging findings are unspecific and diagnosis is made by exclusion and biopsy. We present a case manifesting as a pseudotumor in the posterior fossa on computed tomography and magnetic resonance imaging. The diagnosis was after biopsy, and the patient evolved favorably after treatment.
