Case in brief
A Japanese man in his 50s, with a history of living in high-altitude rural areas, presented with abdominal distension. Imaging revealed a 15-cm cystic lesion in the left hepatic lobe, consistent with cystic echinococcosis (CE) stage CE3a. Diagnosis was confirmed through serological testing and molecular analysis, leading to laparoscopic left hepatectomy after starting albendazole therapy.
What made this case unusual
The case involved Echinococcus granulosus sensu stricto genotype G3, which is noteworthy for its identification in a nonendemic region like Japan.
Diagnostic / clinical pearl
Clinicians should consider a detailed travel history and utilize imaging, serological, and molecular methods when diagnosing imported cystic echinococcosis in nonendemic areas.
Why it matters
This case underscores the need for awareness of imported infectious diseases in regions where they are not typically encountered, enhancing diagnostic accuracy.
