An intracerebral sporadic mixed cavernous angioma: An extremely rare entity with review of literature

Abstract

Cerebral vascular malformations are non-neoplastic lesions resulting from focal anomalies in the development of cerebrospinal circulation. They tend to be asymptomatic, but in 40% of cases, they can be symptomatic; the four morphological types have been described in standard surgical pathology textbooks such as capillary, cavernous, venous and arteriovenous malformations. Mixed types are very rare and remain exceptional. Computed tomography (CT) and CT angiography lack sensitivity and specificity for accurate diagnosis. Magnetic resonance imaging is the choice of diagnostic modality. A conservative approach is observed in asymptomatic patients. Microsurgical resection is the only definitive treatment in symptomatic patients for supratentorial lesions. Due to the heterogeneity of this entity and ongoing debate about ontogenesis, diagnosis and management, we report the case of an 18-year-old boy who presented with a history of seizures for 3 years.
