Abstract
Pineal cavernous angioma is a vascular malformation that has a prevalence lower than
1%. The etiology is debated. It is believed that it is originated from an autosomal
dominant inheritance or from radiotherapeutic treatment. Complete resection enables
the cure and prevents complications of the natural evolution of the lesion, mainly
hemorrhagic events. A female patient, with 67 years of age, presented mental confusion
and visual acuity deficit, which evolved to periods of psychomotor agitation. A magnetic
resonance imaging (MRI) scan of the head showed a lobulated mass lesion in the pineal
region with hypersignal on T1 and hyposignal on the susceptibility weighted imaging
(SWI) sequence. Hydrocephalus was also noticed. The patient underwent a microsurgery
for complete lesion resection though a supracerebellar/supratentorial access. The
anatomopathology revealed an arteriovenous malformation compatible with cavernous
angioma. The pineal cavernous angioma is a rare malformation that should be considered
in the differential diagnosis of expansive lesions of the pineal gland.
