Distal Duodenal Stricture Secondary to Mesenteric Fibromatosis (Intra-Abdominal Desmoid Tumor) of the Jejunum

Mesenteric fibromatosis (intra-abdominal desmoid tumor) is rare, with only a few cases reported in the literature. Clinical symptoms range from asymptomatic, nausea, early satiety, abdominal pain, and gastrointestinal bleeding. Although histologically benign, such a tumor may become locally invasive, and aggressive forms contribute to significant morbidity and mortality.
