Intracranial extra-axial chondromas: clues to computed tomography and magnetic resonance imaging diagnosis.
Acta Neurol Belg

Department of Neurosurgery, Bahçeşehir University School of Medicine, Göztepe Medical Park Training and Education Hospital, Istanbul, Turkey.
Article Synopsis
- This study focuses on analyzing the CT and MR imaging characteristics of intracranial extra-axial chondromas in six patients, highlighting their distinct appearances based on location.
- The researchers found that frontal chondromas typically showed calcification and mixed signals on imaging, while cavernous sinus chondromas displayed bone erosion and intense hyperintensity on T2-weighted images without calcification.
- The study concludes that while there are various imaging features, specific traits like absence of restricted diffusion and distinct signal patterns can suggest the presence of an intracranial chondroma, aiding in diagnosis.

Division of Neurosurgery, Department of Surgery, Specialty Hospital, Amman, Jordan.
BACKGROUND Intracranial chondroma is a rare benign tumor that more commonly arises from the skull base. Chondroma arising from the falx cerebri is very rare, with only 19 cases previously reported in the literature. The imaging characteristics of intracranial chondroma and meningioma can be similar.

Background: Primary intracranial chondrosarcoma is an extremely rare malignant tumor of the central nervous system, which accounts for <0.16% of all primary intracranial tumors. This rare tumor has a high associated morbidity from the tumor itself as well as from treatment modalities.
