We present here the radiological findings of a rare case of multiple focal nodular hyperplasia that was associated with portal vein atresia and portopulmonary hypertension in a young woman. This case illustrates and supports the pathophysiological hypotheses that were previously proposed for the coexistence of these three abnormalities.

Gas in the portal veins is rare and in most cases is associated with serious diseases and poor clinical outcome. A case of gas in the hepatic-portal veins with gastric dilatation, as shown by CT-scanning for abdominal trauma, is reported. The condition was clinically benign and resolved spontaneously. An abdominal CT scan documented the findings.

PURPOSE: Classically air in the portal vein has been detected on plain radiography, but computed tomography and ultrasonography have been shown to be more sensitive. We report a case of air in the PV in a 10-day-old infant with pneumatosis intestinalis with its ultrasonographic and Doppler findings. MATERIAL AND METHODS: The patient was a 10-day-old infant born by cesarean section at 41 weeks. Simple abdomen film revealed branching pattern of radiolucent air shadows within the contour of liver, gas distention of bowel loops and thickenod bowel walls with lincar intraluminal air shadows in abdomcn, suggesting neerotizing enterocolitis. So we performed Doppler ultrasonography. RESULTS: Ultrasonography showed branching pattern of hyperechogenic dots along the lumen of left portal vein. The color Doppler study revcaled an aliasing duo to increased velocity and whirling pattern of blood flow, and the Duplex Doppler spectral display showed sharp, vertical bidirectional spikes by air in portal vein. CONCLUSION: Air in the portal voin can be easily diagnosed by the followign signs:hyperechogenic dots in the portal vein on ultrasonography and vertical, sharp bidirectional spikes superimposod on the usual Doppler tracing of the portal vein on Duplex ultrasonography.

Hepatic portal venous gas (HPVG) is an uncommon disease entity that usually has grave prognosis. It is generally associated with bowel necrosis, and has been reported in a wide variety of conditions such as ulcerative colitis, Crohn's disease, diverticulitis, intestinal ischemia, or infarction. We experienced two cases of HPVG associated with acute pancreatitis. HPVG was found in patients with severe necrotizing pancreatitis and concurrent bowel ischemia. Despite aggressive resuscitation with fluids and broad spectrum antibiotics, each patient developed multiorgan failure, and died within few days. Acute pancreatitis is a potential cause of severe intraabdominal systemic catastrophe. Moreover, HPVG is associated with bowel ischemia in the setting of acute pancreatitis which could lead to rapid aggravation of symptom and complicated clinical course. Therefore, vigilant and aggressive management should be warranted in such condition.

We present a case of portal and superior mesenteric venous gas in a 31-year-old diabetic woman with a left-sided retroperitoneal abscess. Five years prior to admission, patient was diagnosed with diabetes mellitus and developed emphysematous pyelonephritis, requiring nephrectomy on the left side. A CT examination showed air distributed throughout the portal venous system and superior mesenteric vein.
