Abstract

Although various treatment modalities have been introduced, the management of large cystic metastatic brain tumors is not clearly established. In some cases, stereotactic cyst aspiration followed by radiotherapy or radiosurgery improve patient quality of life. Ommaya reservoir placement is one useful treatment option for large or recurrent cyst-forming metastases that allows for reduction of tumor volume prior to radiosurgery. Although Ommaya reservoir placement is a relatively low risk procedure, some morbidity occurs rarely. In particular, metastasis along the Ommaya reservoir cannula in patients with metastatic brain tumors is extremely rare. We report a patient with a large, cystic, metastatic brain tumor that spread along the Ommaya reservoir cannula.

Key Words: Ommaya reservoir, Brain metastasis, Gamma Knife surgery.
