Incidentally found simple hepatic cyst in an asymptomatic 64-year-old male. a Ultrasonography shows a round homogeneous anechoic cystic hepatic lesion, well-circumscribed and without any mural nodule or vegetation. The arrows show an increased through transmission, confirming the cystic nature of the lesion. b T2-weighted magnetic resonance imaging shows a highly hyperintense round lesion. c and d Computed tomography without and with contrast on portal venous phase shows a round homogeneous non-enhancing hypoattenuating lesion (3 Hounsfield Units)
