Click 60-year-old woman with pylephlebitis of the inferior mesenteric vein due to sigmoid diverticulitis.
Axial images of the initial abdominal CT show pylephlebitis with a central hypodense filling defect, gas in the thrombosed inferior mesenteric vein with surrounding edema and peripheral hyperdensity, lymphadenopathy and inflammatory changes, in the setting of diverticulitis with wall thickening of the sigmoid colon. The inferior mesenteric vein shows, in this case, a variant drainage into the superior mesenteric vein.
Images obtained by a multidetector scanner; Protocol: 120 kV, with a max. of 230 miliamperes; slice thickness, 2.5 mm; intravenous contrast medium iomeprol 400 mg/mL; total contrast dose, 80 ml; oral and rectal contrast medium megluminioxitalamat 300 mg iodine/mL; total contrast dose, 30 mL.

Coronal images of the initial abdominal CT show pylephlebitis with a central hypodense filling defect, gas in the thrombosed inferior mesenteric vein with surrounding edema and peripheral hyperdensity, lymphadenopathy and inflammatory changes, in the setting of diverticulitis with wall thickening of the sigmoid colon. The inferior mesenteric vein shows, in this case, a variant drainage into the superior mesenteric vein.
