[Primary choroid plexus papilloma presenting as a cerebellopontine angle mass lesion]. 1986

O Hirai, and J Yamashita, and J Takahashi, and H Handa

A rare case of primary choroid plexus papilloma of the cerebellopontine angle, which might have been originated from the lateral choroid plexus of the fourth ventricle and proliferated into the extraventricular space, is reported. The patient had no neurological abnormalities except for recurrent episodes of headache. Although radiological examinations did not offer a definitive diagnosis, he was successfully treated by operation without any neurological deficit. So far reported in the literature, the number of such cases is less than twenty, and the prognosis has been reported not so good despite benign biological nature. The size of the tumor and preoperative symptoms appear to determine the prognosis. It should be emphasized that an early diagnosis and early surgical treatment are extremely important for this kind of lesions.

D002528	Cerebellar Neoplasms	Primary or metastatic neoplasms of the CEREBELLUM. Tumors in this location frequently present with ATAXIA or signs of INTRACRANIAL HYPERTENSION due to obstruction of the fourth ventricle. Common primary cerebellar tumors include fibrillary ASTROCYTOMA and cerebellar HEMANGIOBLASTOMA. The cerebellum is a relatively common site for tumor metastases from the lung, breast, and other distant organs.

D002551	Cerebral Ventricle Neoplasms	Neoplasms located in the brain ventricles, including the two lateral, the third, and the fourth ventricle. Ventricular tumors may be primary (e.g., CHOROID PLEXUS NEOPLASMS and GLIOMA, SUBEPENDYMAL), metastasize from distant organs, or occur as extensions of locally invasive tumors from adjacent brain structures.

D004806	Ependymoma	Glioma derived from EPENDYMOGLIAL CELLS that tend to present as malignant intracranial tumors in children and as benign intraspinal neoplasms in adults. It may arise from any level of the ventricular system or central canal of the spinal cord. Intracranial ependymomas most frequently originate in the FOURTH VENTRICLE and histologically are densely cellular tumors which may contain ependymal tubules and perivascular pseudorosettes. Spinal ependymomas are usually benign papillary or myxopapillary tumors.
