The left hepatic lobe contains an inhomogeneous cyst (CE4). A large splenic cyst (CE1) is just below visible.
A CE2 cyst is evident among bowel loops.
A CE3 collapsed cyst is detected at the left flank.
Uniloculated hepatic cyst and large splenic cyst with irregular border and hyperattenuating septum, consistent for contained rupture.
The hepatic cyst shows hyperattenuating rim on caudal level.
Collapsed cyst with hyperattenuating rim at the left flank.
On more caudal level air bubble within the collapsed cyst is appreciable; fluid collection surrounds the descendent colon. Another cyst with hyperattenuating rim is also shown.
The collapsed cyst appears inhomogeneous on post-contrast image.
The cyst appears medially attached to the descendent colon, displaced and angulated.
Sagittal reformations (left side) shows multiple cyst in different evolutive phases.
