Angioinvasive gastrointestinal mucormycosis with duodenal necrosis and perforation in a patient with visceral myopathy.

A 55-year-old woman with a past medical history of visceral myopathy with multiple resultant abdominal surgeries, colectomy caused by severe pseudo-obstruction, and end-stage renal disease on hemodialysis presented with complaints of nausea, abdominal distention, vomiting, and diarrhea for five days. Small-bowel obstruction was identified on CT. She subsequently developed acute gastrointestinal bleeding, anemia, and hemodynamic instability.
