“…On ultrasound, they were complex cystic lesion with well-defined walls with multiple septa daughter cysts and internal echogenic matrix. These findings correlate with study done by Lewall et al [25] …”

“…On the other hand, suppurated hepatic cysts and echinococcal cysts do not generally pose diagnostic problems. Sonography can easily differentiate the mobile internal debris typical of abscess formation or the multilayered appearance of the echinococcal cystic wall, and only an unexperienced sonographer can confuse the multiloculated appearance of cystadenoma with multiple daughter cysts of echinococcus [18] . When in doubt, the presence of antiechinococcal antibodies is diagnostic.…”

Biliary cyst tumors (cystadenoma and cystadenocarcinoma) are an indication for liver resection. They account for only 5% of all solitary cystic lesions of the liver, but differential diagnosis with multiloculated or complicated biliary cysts, atypical hemangiomas, hamartomas and lymphangiomas may be difficult. The most frequent challenge is to differentiate biliary cyst tumors from hemorrhagic cysts. Computerized tomography (CT) and magnetic resonance imaging (MRI) are often not diagnostic and in these cases fine needle aspiration (FNA) is used to confirm the presence of atypical biliary cells. FNA, however, lacks adequate sensitivity and specificity and should always be used in conjunction with imaging. Pre-operative differentiation o f c y s t a d e n o m a f r o m c y s t a d e n o c a r c i n o m a i s impossible and surgery must be performed if a biliary cyst tumor is suspected. When multiple cystic lesions are observed throughout the liver parenchyma, it is important to exclude liver metastasis, of which colonic cancer is the most common primary site. Multiple biliary hamartomas (von Meyenburg complex) can appear as a mixture of solid and cystic lesions and can be confused with cystic metastasis. Strong and uniform T2 hyperintensity on MRI is usually diagnostic, but occasionally a percutaneous biopsy may be required.

“…Hydatid disease is a worldwide zoonosis caused by the Echinococcus tapeworm. Ultrasound features are characteristic although they may vary and several classifications based on the cyst appearance have been proposed [2,3]. EUS (as in our patient) can be equally effective in providing high resolution images to demonstrate characteristic cyst features when other imaging modalities are unreliable or unavailable [4].…”
