A case of heterotopic gray matter in the left subepcndymal region is reported. The patient was a 16 year-old female who was admitted to the Department of Neurosurgery on March 10, 1978 with chief complaints of syncope and generalized convulsion. Neurological examination on admission revealed no abnormalities. CT scan showed a broad-based isodense mass in the dilated left lateral ventricle, which was not enhanced by contrast media. Pneumoencephalography revealed a round defect in the center of the left lateral ventricle. On April 12, 1978, the left lateral ventricle was entered through a corticotomy, and a round lump covered by ependymal wall was discovered at the posterior part of the foramen of Monro. This bulging mass was completely removed. CT Scan after surgery showed that no mass remained. Histopathologically, cells were noted and mild gliosis and some scattered neuron. This specimen was regarded as a gray matter. No malignancy was identified. Postoperatively, she was free from any convulsions or syncope. In this case, CT scan was a useful diagnostic procedure among other neuroradiological studies for differential diagnosis.
