Malignant choroid plexus papilloma is a rare disease. The autopsy case of malignant choroid plexus papilloma being suggestive of the youngest in Japan, was reported.

This 8-months-old baby had normal delivery history, and the development and growth were not eventful.

The patient admitted to the University hospital because of projecting vomiting and meningcal irri-tating signs at 7.5 months in age, and septic meningitis was most suspected. He died 2 weeks after the admission.

At autopsy, a large papillary tumor with marked necrosis and hemorrhage was seen in the right lateral ventricle. The right lateral ventricle was almost replaced by the tumor.

The metastasis to the brain base and the sliced-ing to the subarachinoidal space of the cerebellum were noted.
