Supratentorial Convexity Dural-Based Cavernous Hemangioma Mimicking a Meningioma in a Child

A case of a convexity dural-based cavernous hemangioma in a 15-year-old male child is reported. The child presented only with headaches and had no neurological deficits. MRI features were suggestive of a meningioma. The tumor was completely resected and histology was conclusive of a hemangioma. At follow-up after 2 years, the child is asymptomatic and MRI showed no evidence of the lesion. Supratentorial convexity dural-based hemangioma in a child is rare and hitherto only 1 case has been reported in the world literature. Complete resection of the lesion is curative and long-term prognosis is excellent. The uniqueness of the present case is the supratentorial convexity dural-based location, innocuous presentation and unusual radiological features on MRI. The clinical profile, radiological features and management of cavernous hemangiomas in a child are discussed and the current literature is briefly reviewed. Copyright (C) 2009 S. Karger AG, Basel
