title: Intracranial extra-axial chondroma: a case report.
abstract: Intracranial chondroma is a rare benign neoplasm that occurs most often at the skull base. In extremely rare instances, it arises from the dura mater of the convexity or from the falx cerebri. The tumor cells are thought to originate from meningeal fibroblasts, perivascular mesenchymal tissue, or ectopic chondrocytes. Because the clinical presentation of such cases is nonspecific and because neuroimaging findings are not pathognomonic, intracranial chondromas mimic other intracranial tumors. Herein, we report a chondroma originating from the dura mater in the frontal region. The patient had been followed-up radiologically for 3 years after a preliminary diagnosis of meningioma until the correct diagnosis of chondroma was established with postoperative histological examination.
