Abstract: In the present study 50 skulls (dry specimens) of known sex were studied in detail. In one of the male specimen a very well defined tubercle measuring 3 mm by 5mm was observed on the clivus at the junction of upper 1/3 and lower 2/3. Clivusmeningiomas and clivuschordomas are the common conditions in this region. Lateral and frontal tomography help in diagnosis.1The symptoms produced are because of the compression on the brain stem or arteries and nerves related.
