[Choroid plexus carcinoma with metastasis to bone (author's transl)].

A very rare case of the choroid plexus carcinoma of the left lateral ventricle with metastasis to bone was reported. A two-month-old baby was suffering from irritability and vomiting. Her vital signs became progressively worse. On admission she showed an increased head circumference and meningeal irritation signs. An emergency tapping of the right lateral ventricle at the anterior fontanel revealed the bloody csf and an opening pressure of over 700 mm of water. All laboratory findings were negative. Cerebral angiograms showed only an internal hydrocephalus. CT scan and conray-ventriculography gave the finding of a tumor at the trigone of the left lateral ventricle. The tumor was removed "en bloc". Histological examination of the tumor revealed a choroid plexus carcinoma, which was considered met the criteria given by Russell and Rubinstein. The postoperative course was very complicated with metastasis to the right tibia, which was verified by needle biopsy. The patient died from a cachexia. This case was the youngest of all reported cases and very unique in the point of which the tumor metastasized to outside of the central neural axis.
