DOI : 10.5137/1019-5149.JTN.25478-18.2 Intracranial chondromas are unusual benign tumors. They commonly occur at the base of the skull, whereas an intraventricular type is very rare.

We present the case of a 19-year-old female patient with a giant intraventricular chondroma detected incidentally by imaging after a car accident. The spiral head CT scan and MRI findings revealed a large solid mass with a lobular border and coarse calcified components. A wide craniotomy was performed, and a very firm tumor was observed with no internal debulking capacity. The tumor was completely removed in one piece.

Differentiation of an intraventricular chondroma from other intraventricular lesions, such as choroid plexus carcinoma, meningioma, and cavernoma, is of great importance in neuroimaging and surgical planning. Keywords : Brain tumors, Craniotomy, Intraventricular, Chondroma
