Presumptive case of sparganosis manifesting as a hepatic mass: A case report and literature review

Abstract

A 60-year-old man was admitted due to rectosigmoid colon cancer, and a hepatic mass was incidentally found during the staging work-up. The mass appeared cystic with a thick wall and contained multiple bizarre cord-like structures on ultrasound, computed tomography and magnetic resonance imaging. The differential diagnoses included organizing abscess/hematoma, foreign body granuloma and parasite infestation. Serologic study revealed anti-sparganum antibodies. Over 4-year follow-up, the patient did not complain of symptoms, and no changes in the characteristics of the liver mass were observed. Hepatic sparganosis is rare; only two cases have been clinically reported, and no detailed radiologic description was available until now. This case report presents a detailed radiologic description of a hepatic mass that could most likely represent hepatic sparganosis.

A hepatic sparganosis misdiagnosed as intrahepatic mass-forming cholangiocarcinoma: a case report and literature review

“…Sparganosis, especially HS, is rare and there are no definite diagnostic guidelines worldwide; only case reports have been published. Jo et al (19) reported CT, MRI, and ultrasound imaging findings from one case of HS and discovered that HS manifested as a well-defined, heterogeneous hypoechoic mass on ultrasound examination, with no tumor vessels being observed, whereas CT and MRI findings suggested the presence of a nonenhanced serpentine tubular structure inside the mass, and the diffusion of the DWI sequence was not limited. This patient had no other complaints, and the lesion in the liver was detected during an abdominal CT study performed for the staging of the rectosigmoid colon cancer.…”

“…Thus, these measures are highly useful as effective auxiliary diagnostic tools for sparganosis. Worm species can be identified by sequencing [9][10][11]. Unfortunately, due to the improper preservation method of the parasite in this case, further molecular analysis of the parasite could not be carried out.…”
