Classical intracranial chondrosarcoma: A case report.

Abstract

Intracranial chondrosarcoma is a rare malignant cartilage-forming tumor, with only a small number of cases in the posterior cranial fossa reported previously. The present study reports the case of a 40-year-old male patient who was admitted to Tianjin Huanhu Hospital with a progressive headache and dizziness that had lasted for 2 years. Physical and neurological examinations were normal. Radiography of the skull identified an opaque lesion in the left frontal region of the brain. Cranial computed tomography and magnetic resonance imaging revealed a lesion with calcification and homogenous contrast enhancement in the left frontal region. Subsequently, the patient underwent bicoronal craniotomy and gross total resection of the tumor. Pathological examination confirmed the diagnosis of classical intracranial chondrosarcoma. The patient was discharged 10 days after surgery, with no neurological deficit. One month after initial discharge, the patient underwent γ-knife treatment. A follow-up examination 9 months after surgery revealed that the patient was still alive and had returned to work, with no obvious symptoms or evidence of recurrence.
