Abstract
Intracranial extraskeletal. mesenchymal chondrosarcoma is a rare malignant variant of chondrosarcomas. We present a 5-year-old Saudi male child who was brought to the Emergency Department with the complaints of headache, irritability, vomiting, and unsteadiness of gait with right hemiparesis. Radiological studies confirmed the presence of a space-occupying lesion in the left cerebral hemisphere of the brain. Through a left temporoparietal craniotomy a total macroscopic excision of the tumor was carried out, and the tumor was found attached to the dura at the base of the temporal fossa. The tumor was well circumscribed, extra axial in location, and was easily dissected from the other part of the brain. The histopathological examination revealed the tumor to be a mesenchymal chondrosarcoma. This rare tumor of the pediatric age group should be included in the differential diagnosis of all intracranial tumors with aggressive characteristics.
