title: [An operated case of clivus chondroma (author's transl)].
abstract: A case of clivus chondroma was presented in detail with a review of twenty-four cases reported in Japan. A twenty-eight-year-old house wife was admitted to hospital with complaints of muscle weakness and numbness on the right side of the body. Neurological examination revealed the right hemiparesis and hemihypesthesia. Cranial nerve palsies were also disclosed on the right Vth and the left IXth, Xth and XIth nerves. Craniograms showed a ring-like calcified shadow localized in the clival region without definite bone destruction. Roentgenograms disclosed many well-demarcated radioluscent areas in the phalanges of both hands and feet. The marked separation between the basilar artery and the clivus was demonstrated on vertebal angiograms and pneumoventriculograms. CT scan showed an irregularly shaped low density area localized on the clivus, which turned out to be enhanced following contrast infusion. The tumor was partially removed by the subtemporal approach, and was histologically chondroma. The patient was discharged, gaining adequate muscle strength after operations.
