“…EUS was recently reported to be among the effective modalities to differentiate AE from other cystic neoplasms [ 7 , 14 ]. These images can help in the diagnosis of AE and its differentiation from other malignant lesions, and it has been reported that surgery remains the only definitive diagnostic and therapeutic tool [ 3 , 7 ]. However, EUS-FNA for AE has the risk of seeding and anaphylaxis from spillage or leak of cystic fluid [ 7 , 8 ].…”

“…However, in nonendemic area, it is not always easy to differentiate AE from other neoplasms by these images and serological test [ 4 , 5 ]. EUS fine-needle aspiration (EUS-FNA) to diagnose AE is contraindicated because it may cause seeding and because of the risk of anaphylaxis from spillage or leak of cystic fluid during FNA [ 7 , 8 ]. There are, therefore, few reports of patients who had no other alternative but to be diagnosed as having AE with EUS-FNA [ 9 , 10 , 11 ].…”

A 37-year-old man had an asymptomatic 17-mm mass in the liver by health check with ultrasonography. Five years later, he was referred to our hospital because the mass was slightly enlarged with a peripancreatic lymph node. We performed endoscopic ultrasonography fine-needle aspiration (EUS-FNA) to evaluate a lymph node, but it showed amorphous eosinophilic material and eosinophilic infiltrate in necrotic tissue of toothpaste-like white specimen. However, we diagnosed as potentially malignant liver mass with lymph node metastasis because of 2-deoxy-2-(fluorine-18) fluorodeoxyglucose uptake. We then performed hepatectomy and enucleation of the pancreas. DNA polymerase chain reaction analysis revealed Echinococcus multilocularis infection. Retrospectively, we could find a part of Echinococcus in the specimens of EUS-FNA.
