title: Undifferentiated embryonal sarcoma of liver in an adult masquerading as complicated hydatid cyst.
abstract: Benign or malignant hepatic lesions may rarely mimic inflammatory lesions on imaging. We describe a case of young adult male presenting with pain abdomen and fever of short duration. Imaging revealed large complex multiseptated lesion in the right lobe of liver. Complicated hydatid cyst was kept as first differential diagnosis depending on clinic-radiologic findings. However, due to few atypical imaging features, FNAC of the lesion was performed which confirmed the lesion as UESL.
