Appendix, Arteriovenous malformation, Acute abdomen, Rare

Introduction Arterio-venous malformations (AVM) are architectural abnormalities of blood vessels. Appendicular AVMs are rare and we present one presenting as acute abdomen. Case study 44-year healthy male presented with lower abdominal pain and vomiting. He was ill, but the vitals were stable. His abdomen was distended with a mass palpable on the central and left lower quadrant with localized peritonitis. Inflammatory markers were high. USS showed a large heterogeneous mass within the peritoneal cavity with focal hemorrhagic areas and free fluid mimicking a bleeding GIST. CECT showed 10*12*8 cm size enhancing lesion occupying the pelvis with significant peri-lesion stranding, compressing the bladder and bowel with few mesenteric lymph nodes. Liver was normal. CECT Differential diagnoses were desmoids and GIST. On laparotomy, pelvic mass was identified attached to the bladder and rectum covered with small bowel loops. On careful dissection there was clotted blood with appendicular tip inside which is unhealthy and ulcerated, and rest of it was normal. Other abdominal organs were normal. Appendectomy was done and sent for histology. Clot removed. Peritoneal lavage done. Patient fully recovered. Histology showed a benign lesion in appendix favoring an AVM with hemorrhagic necrosis. Discussion AVM are congenital architectural disorganizations in blood vessels. About 12% of AVM become symptomatic and present as acute appendicitis or acute abdomen due to bleeding. Almost all the cases of AVM were diagnosed post operatively. Intra-abdominal AVM might be treated pre operatively if found to prevent compilations. Laparoscopy was an option but decided on laparotomy as the mass is large and uncertainty of the diagnosis
