Case report demonstrates rapid clearance of hepatic portal venous gas within 18 hours in an adult female, indicating that conservative management and serial computed tomography can suffice.
Hepatic portal venous gas (HPVG) was detected by CT in a 64-year-old woman who suddenly complained of lower abdominal pain. However, the abdominal symptoms disappeared rapidly, and lower gastrointestinal endoscopy indicated only terminal ileitis. Conservative treatment alone was performed, and HPVG completely disappeared approximately 18 hours later. The use of CT proved to be useful for following the course of HPVG.
