Ectopic Paragonimiasis Presented as Omental Cystic Masses

ABSTRACT

Ectopic paragonimiasis has been diagnosed in many organs, such as the mesentery, peritoneum, omentum, diaphragm, pleura, liver, ovary, central nervous system and subcutis. However, simultaneous involvement of the peritoneum, mesentery and omentum is relatively unusual. A 52 years old woman, who visited our hospital because of abdominal pain, is the subject of this report. A CT scan showed an approximate 3.9x9.0 cm sized omphalomesenteric duct cyst in the left paraumbilical area of abdomen. An explorative laparotomy was performed, and the pathologic diagnosis was nonspecific chronic inflammation, with diffuse foreign body granuloma due to parasitic eggs. Postoperatively, the immunoserologic test for paragonimus wetermani was positive. A case of peritoneal, mesenteric and omental paragonimiasis, presenting as omental cystic masses, is presented, with a brief review of the literature.
