Cavernous malformation of the pineal region. Case report and review of the literature

Cavernous malformations rarely occur in the pineal region with only 21 reported to date. Although its diagnosis is not easy because of the extreme rareness of this condition, the presence of this lesion can be suspected based on its typical radiological findings. We report the case of a 57-year-old woman presented with desorientation, somnolence and diplopy. The CT-scan showed an acute hemorrhage in the pineal region and triventricular hydrocephalus. An MRI suggested a cavernous malformation. The patient was operated with total en-bloc removal of the lesion. We conclude that surgical exploration and total resection is the treatment of choice when the diagnosis of cavernous angioma is suspected of the basis of neuro-imaging.
