Abstract
A 58-year-old male requested a specialist consultation and examination due to hepatobiliary laboratory abnormalities without evidence of leukocytosis or eosinophilia. The patient's life history and medical history were non-contributary. On abdominal ultrasonography, a 13-mm solid tumor was detected in segment 2 of the liver. This tumor was also detected on computed tomography with heterogeneous enhancement. Cholangiocellular carcinoma of the liver was initially suspected. A lateral segmentectomy of the liver was performed. However, the subsequent histopathological findings revealed an epithelioid cell granuloma and the body of a parasite, which led to a diagnosis of visceral larva migrans.
Visceral larva migrans is often difficult to diagnose due to the fact that its symptoms are similar to those of other medical conditions. Nevertheless, there are many clues that can lead to the correct diagnosis, such as the presence of leukocytosis, eosinophilia, and extra-hepatic lesions. In this case, there was no reason to suspect parasitic infectious disease based on the initial investigation. Given the exceedingly rare discovery of the body of a parasite in the resected specimen, this case can be used as a teaching example for diagnosing visceral larva migrans.
