Background: hydatidosis is one of the major zoonotic diseases that cause considerable public health problems in iran. the present study was designed to investigate pediatric hydatidosis in patients referred to the children medical center hospital in tehran, iran during 2005-2010. methods: data were collected from the records of 17 patients referred to the center with hydatidosis. data included demographic data; laboratory results, type, and site of cysts, clinical manifestations, and treatment. results: nine patients were boys (52.9 %) and eight (47.1 %) were girls. most patients referred from central areas of iran (58.8%). seven patients had cysts in their lungs (41.2%) and three cases (17.6 %) in liver. six cases (35.3 %) had simultaneous lung and liver cysts, 3 patients (17.6%) had brain cysts (alone or in combination with other organs involvement) and 2 patients (11.7%) showed multi-organ involvement. all patients were treated by albendazole and underwent surgery, recurrence was seen in 4 (23.5 %) of the cases and one patient died due to rupture of the cyst and anaphylactic shock. conclusion: multi-organ involvement seems to be on the rise in children, this has led to the necessity for physicians to be more aware of clinical features, search, and rule out other organs for involvement diagnosis once a cyst is detected in one organ.
