[Primary Carcinoma of the Choroid Plexus. 2 Case Reports and Review of the Literature]

Primary Carcinomas of Choroid Plexus are seen rarely. In previous literature there were 37 cases which were reported according to Lewis and Russel-Rubinstein malignancy criterias. In this article, we describe 5 years old boy and 1.5 year old girl who suffered from cerebellar ataxia and intracranial pressure increase syndrome. In case 1, the tumor of the fourth ventricle was diagnosed by brachial angiography and ventriculography. In case 2, the diagnosis was established by CT scan. In case 1, the patient died during the postoperative course. In case 2, the postoperative time was unremarkable. A radiotherapy of 3 000 rads was applied to the posterior fossa. One year later, the patient had only mild ataxia.
