Abstract

Meningeal carcinomatosis is an important neurologic complication. It is increasingly being recog- nized as a cause of neurologic disability in life. But stomach cancer has rarely been reported to be a cause of meningeal carcinomatosis. We reported two cases of 46-year-old male and 56-year-oldfemale who were diagnosed gastric cancer by biopsy under fiberoptic gastroscopy. These two cases of stomach cancer with meningeal invasion revealed malignant cells in their cerebrospinal fluid by repeated lumbar puncture. After diagnosis, they were treated radiation therapy in whole brain field. And, now, we have the plan of intrathecal chemotherapy.
