Abstract

The descending duodenum is rarely involved in Schistosoma japonicum (S. japonicum) infection. Here, we report a case of acute Schistosoma infection, which presented with abdominal pain, abdominal distension and irregular fever. Tumor-like lesions were observed in the descending duodenum. Simultaneously, heterogeneity in hepatic perfusion was demonstrated by dynamic computed tomography scanning. Biopsy of the descending duodenum showed the deposition of Schistosoma eggs. Following administration of the antihelminthic drug praziquantel, the patient showed rapid clinical improvement. In conclusion, we report a patient with acute S. japonicum infection presenting as tumor-like lesions in the descending duodenum and heterogeneity of blood perfusion in liver parenchyma.

Core tip:Schistosoma japonicum (S. japonicum) is primarily found in the mesenteric veins and tends to involve the colon, rectum and liver. Here, we report a case of acute S. japonicum infection in a patient presenting with tumor-like lesions in the descending duodenum and heterogeneity of blood perfusion in liver parenchyma.
