ABSTRACT
BACKGROUND: The WHO expert group for echinococcosis recommends percutaneous treatment for the treatment of unilocular echinococcal cysts. In the rare case a hyperergic reaction occurs, it occurs as a type I immediate allergic reaction immediately after the cyst wall puncture.
CASE PRESENTATION: A 6-year-old boy with a unilocular echinococcal cyst in the left hepatic lobe, was treated with cyst puncture / drainage via the right hepatic lobe and falciform ligament under coverage with praziquantel and albendazole. No allergic reaction occurred during the procedure, but three hours later an acute severe hyperergic reaction occurred.
CONCLUSION: Patients who have undergone an invasive therapy or suffered an acute leakage of an echinococcal cyst must be closely surveilled with the possibility of intensive care for at least 24 h after intervention.
