  Fig. 1 (A) Abdominal ultrasonography shows a 1.5 cm-sized well-demarcated, anechoic cystic lesion at segment IV in the left lobe of the liver. (B) Six months later, abdominal ultrasonography shows a cystic lesion measuring up to 2.5 cm in size.

• 

  Fig. 2 Abdominal computed tomography shows a 2.5 cm sized, well-demarcated, oval-shaped, low attenuated cystic lesion at segment IV in the left lobe of the liver.

• 

  Fig. 3 Abdominal ultrasonography shows an anechoic cystic lesion measuring up to 4.5 cm in size.

• 

  Fig. 4 Magnetic resonance imaging findings. (A) T1 weighted imaging shows an approximately 4.8×3.0 cm sized low signal intensity lesion with an irregular thickness of the wall. (B) T2 weighted imaging shows a high signal intensity lesion with internal thin septations.

• 

  Fig. 5 Abdominal computed tomography shows the cystic lesion measuring up to 4.8×3.8 cm in size.

• 

  Fig. 6 (A) Resected specimen reveals a unilocular cyst with attached liver tissue. (B) Low magnification view demonstrates a well-demarcated cyst with continuous lining cells and fibrous pseudocapsule (H&E, ×40). (C) The cyst-lining cell layer is comprised of simple, cuboidal to columnar, ciliated cells (H&E, ×400).
