Giant cerebellar cavernous malformation in 4-month-old boy. Case report and review of the literature

Abstract

Cavernous malformations (CMs) are rare vascular lesions that affect 0.4–0.9% of the population. The diagnosis of CMs is simple in most typical cases although some lesions may present unusual imaging features: localization, signal intensity, or size. Extremely rare giant CMs can mimic neoplastic lesion because of their size. We report a case of giant cerebellar CM that is more than 6 cm in size, diagnosed in 4-month-old boy. We discuss magnetic resonance findings and histopathological features of this lesion.
