(A) Abdominal CT scan shows a well-defined, low-attenuation lesion in the left hepatic lobe.
(B) Abdominal ultrasound demonstrates an unilocular space with internal echoes consistent with bleeding into the cyst cavity.
(C) T2-weighted magnetic resonance imaging, demonstrating a typical high-intensity signal.
(D) Surgical view showing wide unroofing of the cyst.
