Concomitant bihemispheric cerebral ganglioglioma and hemangioma in an 18-month-old child: Case report

This is a rare case of concomitant bihemispheric cerebral ganglioglioma and hemangioma in an 18-month-old child. There were two identical processes; a combination of ganglioglioma and hemangioma was located in the parieto-occ ipital region of both cerebral hemispheres. The child underwent diagnostic computed tomographic and magnetic resonance imaging examinations for seizur es and right-sided facial palsy, which showed the bilateral presence of par ieto-occipital, oval, well-demarcated, subcortically located processes. A b iparieto-occipital craniotomy was carried out and two well-demarcated abnor malities were observed and both were removed in tote. Two years after the o peration, the boy had normal psychomotor development and remained free from seizures with no therapy required. Repeat magnetic resonance imaging showe d no tumor recurrence. Gangliogliomas are relatively uncommon tumors in chi ldhood, located in the supratentorial compartment and usually associated wi th seizures. Histopathologic and immunohistochemical analysis of the two pr ocesses found in our patient showed them to be a ganglioglioma and a hemang ioma, confirming the dysontogenetic origin of these alterations and the ass ociation between malformations and tumor growth. The combination of ganglio glioma and hemangioma, especially bilateral presentation of two such identi cal processes in a young child, is very rare and was not found in the recen t literature.
