“…Secondary MVT is a condition where an underlying disorder induces a state of thrombophilia, venous stasis, and vascular injury within the bowel which all contribute to the formation of a thrombus. 4 Although the pathophysiological association between PVT and MVT are not clear, increased venous pressures within the sigmoid vein, a branch of the mesenteric venous system, can cause profound bowel wall edema. Due to the extensive presence of collateral veins surrounding the sigmoid colon, chronic MVT should be suspected.…”

This case report presents a rare complication of hepatic cystic echinococcosis in a 12‐year‐old Latino male, residing in a nonendemic region, who developed long‐term sequelae of portal vein thrombosis accompanied by the emergence of a hyper‐vascular sigmoid colon mass. Portal vein involvement in hepatic cystic echinococcosis is exceedingly uncommon, with limited documented cases. The presentation of the patient included intermittent hematochezia, abdominal pain, and fatigue. Imaging revealed liver cysts and chronic portal vein thrombosis with cavernous transformation, resulting in portal hypertension. Notably, the patient also exhibited mesenteric venous thrombosis, further complicating the clinical picture. The diagnosis was confirmed through echinococcus serology testing. Treatment involved a six month course of Albendazole, puncture‐aspiration‐injection‐reaspiration procedure, splenectomy, and splenorenal shunt to alleviate portal hypertension. This case underscores the significance of considering portal hypertension secondary to hepatic cystic echinococcosis, even in nonendemic regions, particularly in pediatric patients with unique clinical presentations.
