장 게실염에 동반된 녹농균 패혈증에 의한 문맥염 및 간 농양 1예

Pylephlebitis, or suppurative thrombophlebitis of the portal venous system, is a rare condition occurring secondary to abdominal infections such as diverticulitis. Pylephlebitis can be diagnosed via ultrasonography or CT scan, and is characterized by the presence of a thrombus in the portal vein and bacteremia. However, the diagnosis may be delayed due to the vague nature of the clinical symptoms, causing morbidity and mortality due to pylephlebitis to remain high. Early diagnosis and immediate antibiotic therapy are important for favorable prognosis. Therefore, pylephlebitis should be considered in the differential diagnosis for cases of nonspecific abdominal pain and fever. We report a case of pylephlebitis secondary to diverticulitis, associated with Pseudomonas aeruginosa sepsis. Such cases have not been widely reported. (Korean J Gastroenterol 2016;67:327-331)
