Complications arising in simple and polycystic liver cysts

Figure 1 Computed tomography. A: The liver cyst causing common bile duct compression and dilation of the intrahepatic bile ducts; B: Multiple liver cysts with free fluid around the liver; C: The cyst compressing the portal vein; D: The splenic varices from the resulting portal hypertension.

Figure 2 A cross-sectional magnetic resonance imaging scan confirming the homogenous appearance of the cysts suggestive of a simple liver cyst.

Figure 3 Coronal magnetic resonance image showing the liver lesion with apparent internal membranes extending from segments V and VI of the liver to the right iliac fossa.

Figure 4 The resected liver cyst of patient 3 with attached small bowel.

Figure 5 A transverse section of the abdomen on computed tomography scanning. The left 4 panels represent cranio-caudal sections of the abdomen while the right 4 panels represent magnifications. Panel 4 shows the normal inferior vena cava (CV) and aorta (A), but the CV becomes compressed as can be seen in panel 1-3.

Figure 6 A positron emission tomography-computed tomography scan during the infection (A) and after treatment (B). Picture A shows appearances consistent with multiple infectious cysts, with a medium intense, circular fluorodeoxyglucose-accumulation in the middle of the right liver.
