Giant omental cyst in children presenting as pseudoascites.

An unusual case of omental cyst is described. During a period of 3 years, a child was hospitalized seven times in five different hospitals for evaluation of ascites of unknown origin. Extensive and repetitive diagnostic workup did not reveal the cause of his problem, and recurrent paracentesis improved his condition partially, but for very short periods. A diagnostic laparoscopy, followed by explorative laparotomy, led to the correct diagnosis and appropriate surgical treatment, with complete relief of his complaints.
