Treatment strategy for the tumor cyst of the medulla in an eloquent area: a case report and review of the literature

Abstract

Surgical treatment of intramedullary cystic neoplasms is a challenging problem. This is a clinical case of a 24-year-old woman with the unrescetable cystic tumor of the medulla because of eloquent area involved and severe neurological symptoms caused by the recurrent cystic component. The patient underwent emptying the cyst twice previously by means of safe entry zone myelotomy. Later there was a recurrence of the cyst with a significant neurological and oweral deterioration which is typical for such neoplasms. Recurrent cystic mass-effect was resolved with the help of newly designed device implanted. It provided simultaneous stable cisternal drainage and an opportunity for active aspiration via Ommaya reservoir.
