Cerebral ganglioglioma: a case report

Ganglioglioma (GG) is a benign and rare tumor of the central nervous system, typically located supratentorially in the temporal lobe. Subtentorial localization, particularly in the cerebellum, is uncommon.It represents 0.4% to 7.6% of all central nervous system tumors, 1.3% of brain tumors, and only 1% of intramedullary tumors. Clinically, supratentorial GG causes epilepsy, while subtentorial GG leads to focal neurological deficits due to local mass effect and signs of increased intracranial pressure. A benign brain tumor, called a ganglioglioma (GG), can sometimes be found in the cerebrum. We describe an unusual pediatric two cases of supra and subtentorially GG with a spinal cord localisation in this article. Our patient suffered from headache and epilepsy. Magnetic resonance imaging of the skull revealed a giant cyst with a mural nodule in the right cerebellar hemisphere that flattened the fourth ventricle. Pilocytic astrocytoma was the provisional diagnosis on the basis of clinical and imaging details. After biopsy and immunohistochemistry of the extramedullary intra dural process revealed the presence of a GG. Although GG is an uncommon tumor, it should be included in the differential diagnosis of a cerebellar mass with cystic and solid components in children.
