A Case of Meningeal Carcinomatosis in Which Hearing Loss Was Improved by Radiotherapy

Meningeal carcinomatosis develops when a malignant tumor spreads to the arachnoid or subarachnoid space of the brain and spinal cord, causing a variety of neurological symptoms, and in general, is known to carry an extremely poor prognosis. In this report, we present the case of a 48-year-old woman who developed acute sensorineural hearing loss during treatment for breast cancer, and was diagnosed as having meningeal carcinomatosis based on a history of spinal metastasis and head imaging findings. This case report serves to highlight the possibility that chemoradiotherapy might be useful even in patients with advanced breast cancer with meningeal carcinomatosis, not only to obtain improved hearing, but also prolong the life expectancy.
