Nursing home dweller with dementia and end-stage renal failure. Brought to the ER due to weakness and feculent vomiting. Diffuse abdominal tenderness, and feculent material in the NGT.

CT abdomen showed small bowel obstruction due to an incarcerated right femoral hernia. The contents of the hernia were thought to be a focal wall of the ileum but at surgery, turned out to be a partly ischemic Meckel diverticulum. A Meckel diverticulum incarcerated in a femoral hernia is termed a Littre hernia.
