Gastric Pneumatosis from Isolated Gastric Calciphylaxis.

A 58-year-old man with end-stage renal disease presented with hypotension and emesis, pale conjunctivae, and a distended abdomen. Labs revealed hypercalcemia and leukocytosis. Abdominal imaging showed gastric pneumatosis. Endoscopy demonstrated significant hemorrhage and necrosis in the gastric cardia and fundus. Biopsies revealed acute ulcerative gastritis and focal intravascular calcium phosphate crystals. The patient remained nil per os and was placed on omeprazole and sucralfate. Repeat endoscopy demonstrated mucosal healing. Gastric calciphylaxis in the setting of gastric pneumatosis is an uncommon finding, especially in patients without cutaneous findings.
