Abstract

Leptomeninges are a rare region for metastasis in solid tumors. The most common causes of leptomeningeal metastasis are breast cancer, lung cancer, melanoma and leukemia-lymphomas. Leptomeningeal metastasis associated with gastric cancer is an exceedingly rare condition but it is rapidly progressive and poor prognosis. The diagnosis is confirmed by examination of the cerebrospinal fluid and imaging methods. There are several treatment options for patients with LMC, including intrathecal chemotherapy with or without radiotherapy. In this report, we present a women patient with metastatic gastric cancer leading to spinal leptomeningeal metastasis. While magnetic resonance imaging of the brain showed no pathology, magnetic resonance imaging of the thoracal spinal vertebrae showed leptomeningeal enhancement of Th1-6 level. Cytological examination of the cerebrospinal fluid revealed the tumor cells like signet ring cell. These findings were consistent with leptomeningeal metastasis.
