This case report focuses on hydatidosis, one of the most important parasitic zoonoses in Romania. We describe an interesting paediatric case of an eight-year old boy from a rural region presenting with a both giant and life-threatening pulmonary cyst (that was successfully managed) and a hepatic cyst. Noteworthy are the negative consequences of this disorder on children's health and development as a result of prolonged hospitalizations, surgical interventions and chemotherapy.
