Falx chondroma with hyperostosis of the scull: a case report.

INTRODUCION Intracranial chondroma is a very rare, slow growing, benign cartilaginous tumor that arises usually from the base of the scull. Chondroma located at the falx is extremely rare. According to our best knowledge 15 cases of falx chondromas have been reported in the literature. CASE OUTLINE This is the first case report of falx chondroma located in the parietal area associated with hyperostosis. Magnetic resonance imaging of the brain revealed a 3x4x4 cm solid, calcified, ring-shaped, well-defined tumor at the posterior falx.The patient underwent surgery and complete resection was performed. Histological examination confirmed chondroma of the falx. Postoperative CT scan showed no residual of tumor and the patient was discharged. CONCLUSION The long-term prognosis is good after a total excision of the tumor. Awareness of this rare pathology in the differential diagnosis of falx mass could facilitate the diagnosis.
