Basal ganglionic angioleiomyoma.

A rare case of basal ganglionic angioleiomyoma in a 12-year-old girl is reported. She presented with features of raised intracranial tension, multifocal seizures, left hemidystonia and apraxia of eyelid closure. Cranial CT scan showed a large hypodense lesion with an enhancing mural nodule in the region of head of the caudate nucleus on the right side. The lesion was extending to the posterior limb of internal capsule postero-medially and to globus pallidus laterally. Another small, hyperdense, enhancing lesion was seen in the region of globus pallidus on the left side. The right basal ganglionic mass was excised through frontal craniotomy. Histopathological, Immunocytochemical and Ultrastructural examination of the right basal ganglionic mass showed features characteristic of angioleiomyoma. Following surgery the patient improved initially with respect to dystonia but worsened later on. Repeat cranial CT, 20 months after surgery, showed bilateral frontotemporal atrophy without any tumor recurrence while the lesion on the left side remained quiescent.
