Reveal Findings

US – Pylyoric muscle measures 4 mm and pyloric channel measures 17 mm. The pyloric mucosa is hyperplastic. The stomach is decompressed. Numerous punctate portal hyperechogenicities are present.

Reveal Discussion

Portal venous gas is typically seen with necrotizing entertocolits but can be seen with Hirschprung’s disease, collagen vascular disease, intestinal obstruction and massive bowel dilation. Portal venous gases have been shown to induce rouleaux formation (red blood cell aggregates). The combination of gas bubbles and blood cell aggregates likely account for the echogenic appearance. Distention and forceful vomiting probably allow venolymphatic escape of gastric gas. Association of pyloric stenosis and portal venous gas is benign and should not deter surgery.
