Figure 1. Hepatic CT and MRI findings. (A, B) Imaging findings of plain CT (A) and T2-weighted MRI (B). Calcifications were clearly detected on plain CT (white arrows). The multilocular cyst (ie, cyst-in-cyst) contained mucus (blue arrows). A hematoma was observed inside (red arrows). (C, D) Imaging findings of dynamic CT (C) and T1-weighted MRI (D). The cystic, mucus-producing tumor contained not only mucus (blue arrows), but also muddy-looking fluid (ie, inspissated bile) (green arrows) and hematoma (red arrows). The cyst wall did not show enhancement, and a partial solid component was observed (orange arrows). CT – computed tomography; MRI – magnetic resonance imaging.
