Apendicitis aguda por hidatidosis apendicular: reporte de caso y revisión de la literatura / Acute appendicitis caused by echinococcus granulosus: report of a case and literature review

RESUMEN

RESUMEN La apendicitis aguda es considerada la causa más común de emergencia quirúrgica en adultos jóvenes; y su asociación con infecciones parasitarias es rara. De éstas, la localización apendicular del quiste hidatídico, es extremadamente rara; y hasta la fecha solo existen reportes en Irán, India, Túnez, Chile y Perú. Se presenta el caso de un paciente varón de 52 años, natural de Puno, sin antecedentes patológicos, que ingresa con un cuadro clínico típico de apendicitis aguda, y que, al ser intervenido quirúrgicamente, se aprecia al apéndice con una tumoración quística, compatible con un quiste hidatídico complicado de Echinococcus granulosus. Posteriormente, se constatan otros tres quistes hidatídicos intrabdominales. No existió antecedente quirúrgicoo traumático, por lo que se considera una localización primaria intraabdominal diseminada, que incluía al apéndice, hígado y peritoneo.

ABSTRACT

ABSTRACT Acute appendicitis is the most frequent surgical emergency instance in young adults; and its association with parasitic infections is rare. Of these particular cases, appendix location of hydatid cyst is extremely rare; and there have been published reports of such cases only in Iran, India, Tunisia, and Peru. We present the case of a 52-year old male subject born in Puno, with no relevant past medical history, who was admitted with a clinical condition typically consistent with acute appendicitis. When this patient underwent surgery, the appendix was found showing a cystic mass, compatible with complicated Echinococcus granulosus hydatid cyst. Later on, three additional intraabdominal hydatid cysts were identified. There was no surgical or trauma past history, so it was concluded this condition corresponded to disseminated primary intraabdominal location of hydatid disease, including the appendix, liver, and peritoneum.
