Development of anaphylaxis during biopsy of cardiac, hepatic, and subcutaneous hydatid cysts.

Abstract

This case report presents a rare occurrence of both subcutaneous and cardiac hydatid cysts in a pediatric patient. A 10-year-old girl admitted with a rapidly enlarging, painful mass in the right dorsal scapular region. During a biopsy procedure under sedation, the patient developed an anaphylactic reaction and subsequent cardiopulmonary arrest. After successful resuscitation, cardiac echocardiography revealed a large hydatid cyst in the interventricular septum. In conclusion, potential complications should always be considered during invasive procedures. In addition, in patients with musculoskeletal masses, a whole-body magnetic resonance imaging may detect and prevent potential complications at an early stage.
