Passage of intestinal (small bowel) cast--an unusual complication of neutropenic sepsis

Passage of intestinal casts-An unusual presentation of Cytomegalovirus enterocolitis

Cytomegalovirus (CMV) is one of the leading opportunistic pathogens affecting immunocompromised patients. We report a case of histologically-confirmed extensive CMV enterocolitis in a young woman after receiving rituximab and tocilizumab for the treatment of autoimmune encephalitis. During the antiviral treatment, she spontaneously excreted small intestinal casts per oral and colonic casts per anus. Even though intestinal cast is an extremely unusual condition, CMV infection should be included in the differential diagnosis.

A case of small intestinal cast causing SBO in complicated intestinal graft-versus-host disease

We report an unusual case of small bowel obstruction caused by an intestinal cast in an 8-year-old female who developed intestinal graft-versus-host disease (GVHD) following two unrelated bone marrow transplants for aplastic anemia, and highlight the pathophysiology, common presentations, and surgical complications of intestinal GVHD from the surgeons' perspective.
