[Gastric necrosis from acute dilatation without underlying psychiatric disorder].

Acute gastric dilatation with necrosis is a rare and severe complication associated with anorexia nervosa, bulimia, and psychogenic polyphagia. The Authors report an unusual case without underlying psychiatric context. Gastric necrosis was suspected based on imaging findings (plain radiograph and computed tomography). The detection of these imaging signs in an appropriate clinical setting, even without underlying psychiatric context, is important to avoid any delay in diagnosis and reduce mortality.
