Reacción anafiláctica secundaria a quiste hidatídico hepático roto / Anaphylactic reaction secondary to a ruptured liver hydatid cyst: case report

ABSTRACT

We report a four years old girl consulting in the emergency room for severe abdominal pain and vomiting secondary to a blunt abdominal trauma during a bicycling accident. A chest and abdomen CAT scan showed ruptured hydatid cysts in the lung and liver and free intraperitoneal fluid. During evolution, the patient developed respiratory distress, bronchial obstruction, a papular exanthema and edema. Due to lack of response to steroids, she was operated excising the ruptured hepatic cyst and performing a peritoneal lavage. The patient had a good postoperative evolution. In a second surgical procedure, the lung cyst was excised. The patient is currently receiving albendazole and is asymptomatic after nine months of follow up.

RESUMEN

La hidatidosis es una enfermedad parasitaria, zoonótica y endémica de gran importancia en nuestro país. El quiste hidatídico no complicado suele ser asintomático y es más frecuente encontrarlo en población adulta, siendo infrecuente su diagnóstico en la población pediátrica. Presentamos el caso de una paciente de 4 años de edad derivada al Servicio de Urgencia del Hospital de Chillán por cuadro de abdomen agudo posterior a trauma abdominal con manubrio de bicicleta, cuyo estudio tomográfico reveló la presencia de quiste hidatídico hepático y pulmonar rotos, que evoluciona con reacción anafiláctica secundaria.
