Rapidly enlarging solitary nonparasitic cyst of the liver in a child presenting as acute abdomen

Symptomatic solitary nonparasitic cysts of the liver (SNCL) are rarely encountered in children, especially rapidly enlarging cysts presenting as acute abdomen. Therefore, it is difficult to establish the pre-operative diagnosis and to determine the treatment protocol of SNCL. While imaging techniques such as ultrasonography and computed tomography are modalities for diagnosis of SNCL, making a pre-operative diagnosis in the case of very large cysts remains difficult. We present a child with SNCL who initially presented with a rapidly enlarging cyst presenting as acute abdomen, and also provide a review of the literature. Moreover, we evaluate the surgical procedures and conclude that total excision of the cysts when possible is a suitable treatment procedure in children.
