- Purpose: To describe peritoneal manifestations of fascioliasis
Materials and methods: We reviewed CT images in 31
patients with fascioliasis confirmed by enzyme-linked
immunosorbent assay (ELISA) (n = 24) or surgery
(n = 7). Image analyses were performed to identify
hepatic, biliary, and peritoneal abnormalities.
Results: Hepatic abnormalities were seen in 28 (90.3 %)
of the 31 patients. The most common finding was caves
sign, which was present in 25 (80.1 %) patients. Three
patients (9.7 %) presented with biliary abnormalities
exhibiting dilatation and enhancing wall thickening of
the bile duct, wall thickening of the gallbladder, and
elongated structures in the bile duct or gallbladder.
Peritoneal abnormalities were seen in 14 (45.2 %) of the
31 patients. The most common peritoneal abnormality
was mesenteric or omental infiltration, which was seen in
9 (29.0 %) patients. Other peritoneal findings included
lymph node enlargement (n = 7), ascites (n = 7),
thickening of ligamentum teres (n = 2), and peritoneal
mass (n = 2).
Conclusion: Peritoneal manifestations of fascioliasis are
relatively common, and CT findings include mesenteric
or omental infiltration, lymph node enlargement, ascites,
thickening of the ligamentum teres, and peritoneal
Key words: Fascioliasis—Computed
