Posterior fossa chondroma arising from the tentorium: a case report

48-year-old woman with a cerebellopontine angle mass

Intracranial chondromas are rare benign neoplasms with an estimated incidence rate of 0.2–0.3%. They usually occur at the skull base, or arise from the dura and leptomeninges. Rarely, they have been reported at the cerebellopontine (CP) angle. Here we describe an interesting case of CP angle chondroma which was clinically and radiologically diagnosed as schwannoma and meningioma.

A Solitary Convexity Dural Chondroma: the Proposed Role of Diffusion-Weighted MR Imaging in the Differential Diagnosis of Intracranial Chondroma and Meningioma. A Case Report

Chondromas arising from the dura mater are rare intracranial tumors. We describe a case of intracranial chondroma originating from the durra mater of the convexity, mimicking a meningioma. The neuroradiological and surgical findings are described. The diagnostic clues for the differential diagnosis between chondromas and meningiomas are discussed and reviewed.

Intratentorial osteochondrolipoma in a 9-year-old boy

Intracranial osteolipomas and chondromas are rare benign tumors. Forty-five chondromas, mostly supratentorial, have been reported in the literature since 1981, with origins most commonly in the sellar regions. Twenty-one osteolipomas have been described to date, usually located near the tuber cinereum or the corpus callosum. The authors present a case of an osteochondrolipoma arising from the tentorium diagnosed in a pediatric patient at the age of 9 years. The case and treatment are discussed, and a review of the literature is provided.

Intracranial falx chondroma: Literature review and a case report

Intracranial chondromas are benign tumors that represent approximately 0.5% of all intracranial tumors. They usually occur at the base of the skull but on rare occasions might present as intra-parenchymal or intra-ventricular space-occupying lesions, most likely originating from heterotopic chondrocytes or metaplastic fibroblasts of the falx, the convexity dura, or the ventricular ependyma. Chondromas are slow-growing tumors, which remain clinically silent for a prolonged period of time in the majority of cases. Their clinical presentation is non-specific and their radiographic appearance usually does not differentiate them from their more common counterparts, such as meningiomas and glial tumors. As a result, their diagnosis has remained a histopathologic one. In our current study, we present a case of a falcine intracranial chondroma. This case provided the opportunity to extensively review the pertinent literature.
