[Meningeal carcinomatosis in occult gastric cancer].

Two cases of meningeal carcinomatosis accompanying occult gastric cancer are presented. The symptomatology in meningeal carcinomatosis is characterized by rapidly progressive, multifocal CNS dysfunction but is otherwise nonspecific so that several differential diagnoses may be considered. Occurrence of carcinoma cells in the cerebrospinal fluid is diagnostic for meningeal carcinomatosis. Treatment is purely palliative.
