title: [A case report of the chondroma arising from the falx cerebri].
abstract: We have reported a case of chondroma arising from the falx cerebri in a 60-year-old female with no neurological symptom. The tumor was revealed as a round mass, attached to the falx cerebri, with marginally scattered calcification on CT scan and with slight enhancement on MRI images. And cerebral angiogram presented a mass with no tumor stain on the external carotid angiography against our preoperative diagnosis of falx meningioma. A subtotal removal of the mass was performed with the diagnosis of chondroma on pathological examination. The chondroma arising from the falx cerebri is extremely rare with only 15 reported cases in the literature. We have presented the first case in Japan and reviewed the previous reports.
