title: Mucinous Cystic Neoplasm of the Liver Masquerading as an Echinococcal Cyst: Radiologic-pathologic Differential of Complex Cystic Liver Lesions.
abstract: Although simple liver cysts are common, complex cystic liver lesions are infrequent and represent a diagnostic and therapeutic challenge. The differential diagnosis of complex cystic liver lesions can be grouped into neoplastic, infectious or inflammatory, and miscellaneous pathologic entities. Clinicians should remember to consider mucinous cystic neoplasm and echinococcal cysts in the differential, which are uncommon etiologies for liver lesions but may expose unique challenges. We present a case of a 49-year-old female who was referred for evaluation of a new complex cystic liver lesion. The following brief review describes how radiologic imaging and pathologic testing can help distinguish between the broad spectrum of diseases that may produce cystic liver lesions.
