(A,B) Ultrasound of the abdomen in a 4-month male infant, revealed a gigantic cystic lesion in the sub-hepatic location, which measured 8.2 × 7.2 × 8.1 cm in size (orange arrows, A,B). The cyst showed intense posterior acoustic enhancement. The contents of the cyst were a few echogenic debris (blue arrow, A). Minimal fluid was seen in the hepatic sub-capsular region (black arrow, B). The cyst was gigantic and resulted in superior displacement of the liver and a posterior displacement of the right kidney (green arrow, C). The gall bladder was localized using a high frequency linear probe and was found to be normal (red arrow, D) (Color version of figure is available online)
