Rapid Growth of Hydatid Cyst: A Pediatric Case Report.

Hydatid disease is a parasitic infection caused by Echinococcus granulosus with worldwide distribution. The most affected organs are liver and lungs, but it can be detected in any other organs as well. We reported a 5-yr-old boy from Shiraz, southern Iran in 2017 who presented with abdominal discomfort. Imaging revealed multiple liver hydatid cyst and a huge kidney hydatid cyst. This case showed the possible implication of rapid growth of multiple hydatid cyst as well as unusual organ presentation in the pediatric population.
