Budd-Chiari syndrome in Behçet's disease.

A 36-year-old man was admitted to the emergency department due to a 30-day history of abdominal distention and epigastralgia. He had described a non-intentional 10kg weight loss, dry cough, and fever 6 months before his admission. He had a history of tobacco and cocaine abuse and reported recurrent oral and genital ulcers. Physical examination showed an extensive area of venous collateral circulation on the abdominal wall, hepatomegaly, signs of a moderate ascites, and lower limb edema. Liver and renal function tests were normal. The ascitic fluid analysis did not show an inflammatory or infectious pattern. Upper flexible endoscopy revealed esophageal fine-caliber varices and colonoscopy showed an isolated terminal ileal ulcer. Abdominal imaging revealed hepatomegaly, voluminous ascites, and thrombosis of hepatic veins, inferior and superior vena cava (Figure 1). Infections and coagulation or lymphoproliferative disorders were excluded. Thereafter, the diagnosis of Budd-Chiari Syndrome in Behçet disease was established and immunosuppression treatment was started with good initial clinical evolution.

Intestinal pneumatosis as a manifestation of systemic sclerosis.

A 60-year-old female patient was admitted to the emergency room for a 7-day history of abdominal bloating, nausea, vomiting, constipation, and lack of flatus. She had been diagnosed with systemic sclerosis (SSc) 10 years ago and had been using methotrexate, sildenafil, and prednisone. She did not present any signs of instability, but physical examination showed malnourishment status and abdominal tenderness and distention. Plain abdominal radiography was suggestive of sigmoid volvulus, confirmed and successfully resolved after endoscopic decompression therapy. Eight months later, the patient developed a new episode of abdominal obstruction. Computed Tomography (CT) scan identified a distended sigmoid colon due to its torsion with gas areas within the bowel wall. This time, endoscopic decompression had failed to treat, so exploratory laparotomy was performed. Colonic distention and sigmoid volvulus were identified during the procedure, after which sigmoidectomy followed by primary anastomosis was performed. Neither perforation nor masses were found. Furthermore, the anatomopathological study was inconsistent with vascular, inflammatory, or neoplastic diseases.
