Mesenteric arteriovenous dysplasia/vasculopathy (MAVD/V) is an exceedingly rare noninflammatory vascular disorder affecting small-calibre mesenteric arteries and veins. This report details a case of a 51-year-old male diagnosed with MAVD/V following abdominal pain and vomiting. Surgical exploration revealed distinctive smooth muscle collarette around subserosal arteries and veins. The rarity of this condition, with only 13 cases reported globally, underscores the importance of recognizing this rare entity to prevent misdiagnosis. Surgical resection remains the curative approach, ensuring a disease-free state after surgery. Awareness of MAVD/V is crucial for accurate diagnosis and avoiding unnecessary prolonged management.
Keywords: fibromuscular dysplasia; mesenteric arteriovenous dysplasia/vasculopathy; mesenteric ischemia; smooth muscle collarette; vasculopathy.
