[A case of ganglioglioma with choked disc]

A case of ganglioglioma associated with choked disc is reported. A 19-year-old girl was admitted to our hospital because of blurred vision. Neurologically, the patient had nothing but choked disc. The CT showed a large cystic mass with calcification in the left parieto-occipital lobe. The MRI revealed that the cyst was delineated by a membrane and that its dorsal side was solid, showing enhancement by Gd-DTPA. Cerebral angiography showed no tumor stain. Left parieto-temporo-occipital craniotomy was performed and the tumor was removed subtotally. Histopathological examination demonstrated the typical pattern of ganglioglioma. The most common symptom of ganglioglioma is convulsions. Symptoms of increased intracranial pressure have been reported sporadically in the literature. It was clinically noted that the cause of the increased intracranial pressure in this patient was enlargement of the cyst associated with ganglioglioma.
