Pre-contrast (A), venous (B), arterial (C) and excretory (D) phases of the current computed tomography scan. Note the evolution of the cyst during the acquisition of the multiphase computed tomography images. The excretory phase (D) demonstrates that the cyst is smaller than the other phases (A, B and C), there is contrast inside and free fluid around (white arrow), also not present on the previous aquisitions.
