Abstract:
The choroid plexus papilloma is a rare tumor. Its incidence is 0.4-0.6% of all intracranial tumors. Most cases of this tumor are found in the young subject, especially infant and childhood but its congenital form is very rare. The clinical and pathologic findings of congenital choroid plexus papilloma are similar to that of any age. But the cilia on the cell surface are common in the former and very rare in the latter. We present a case of congenital choroid plexus papilloma of the lateral ventricle in a 2 month-old male baby. He had suffered from a sudden onset of convulsions and a drowsy mental state for 2 days. The CT scan revealed a large intraventricular tumor in the left lateral ventricle with hydrocephalus. After ventriculo-peritoneal shunt(V-P shunt), his symptoms were improved. But the hydrocephalus was aggravated due to malfunction of V-P shunt, and he recieved the operation after 4 months. The gross examination revealed a large ovoid papillary tumor(4x3x3cm). On light microscopic examination, the tumor showed papillary structure lined by columnar eosinophilic cells. Some cells had cilia. The electron microscopic finding showed intercellular junction, microvilli and cilia. The tumor cells were positive for cytokeratin, vimentin and S-100 protein.
