Rapidly Progressive Dementia due to Carcinoma- tous Meningitis Associated with Gastric Cancer

Abstract

Gastric cancer rarely presents with carcinomatous meningitis (CM) and rapidly progressive dementia. The authors report two cases of carcinomatous meningitis due to gastric cancer presenting with rapidly progres- sive dementia. The MRI of the brain was different between the two cases. The diagnosis of CM was confirmed by positive cerebrospinal fluid cytology.
