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.

[Benign fibro-osseous tumors of the frontal skull base with intracranial extension. Report of 2 cases]

We report on two patients with ossifying fibroma of the anterior skull base with intracranial extension. A psammomatoid ossifying fibroma was removed from a 29 year old female patient, and in a 37 year old female patient a cemento ossifying fibroma was removed. The main clinical symptom in both cases was headache. Surgery took place after diagnosis and therapy in an interdisciplinary operation with ENT colleagues. The ossifying fibroma is a benign neoplasm mainly affecting the maxilla and mandible. Complete removal is better than a curettage of the tumor.

Recurrent osteoma overlying cranioplasty. Case report

✓ An osteoma of the skull was removed from this patient and the bone defect was covered with a cranioplastic plate. Two years later, a recurrent osteoma developed, overlying the plastic plate. There was no connection with the borders of the craniectomy.

Systemic Weber-Christian disease presenting as an intracranial mass lesion. Case report

A case is reported in which systemic Weber-Christian disease presented as a dural mass causing the signs and symptoms of increased intracranial pressure. The literature and possible pathogenesis of this entity are discussed.

Intracranial solitary chondroma. Case report

A case of massive solitary intracranial chondroma involving the base of the skull in a 15-month-old baby boy was successfully treated by total excision. The diagnosis was greatly simplified by the us of computerized tomography, which materially helped in planning the surgical approach.
