| Summary: | Ascariasis is an intestinal disease caused by Ascaris lumbricoides. Most patients with ascariasis
are asymptomatic; however, the presence of many larvae in the bowel can cause gastrointestinal
complications, such as intestinal obstruction, obstructive jaundice, cholangitis, cholecystitis,
and pancreatitis. Herein, we report a case of ascariasis presenting as hematoma and active
bleeding in the sigmoid mesocolon of a 74-year-old man on computed tomography (CT). Sigmoid
colon perforation was also detected on follow-up CT. Laparoscopic low anterior resection
was performed; there was a large hematoma in the sigmoid mesocolon. Roundworms were
microscopically identified in the mesenteric adipose tissue. The clinical and CT findings of this
unusual presentation of ascariasis revealed serial complications during parasite migration from
the intestinal lumen to the peritoneal cavity. |
