Resumen
Objetivo

Presentar un caso de mucocele apendicular confundido con un quiste de uraco infectado. Revisar su diagnóstico diferencial, tratamiento y pronóstico.

Paciente

Presentamos el caso de un varón de 74 años, con dolor abdominal, fiebre y disuria. Imagen compatible con absceso hipogástrico en ecografía y TC. Drenaje percutáneo y tratamiento antibiótico. Enema opaco, colonoscopia y cistoscopia normales.

Resultados

Laparotomía exploradora y exéresis de gran masa adherida a ciego, independiente de vejiga. Resección segmentaria apéndice-cecal. Diagnóstico anátomo-patológico de cistoadenoma mucinoso (mucocele) apendicular.

Conclusiones

Mucocele apendicular y quiste de uraco son patologías poco frecuentes, asintomáticas en la mayoría de los casos. Los mucoceles secundarios a cistoadenoma o cistoadenocarcinoma suelen ser de gran tamaño, llegando hasta la línea media, confundiéndose con quistes de uraco. Diagnóstico mediante ecografía y/o TC. Tratamiento final quirúrgico en ambos, evitando en el caso del mucocele su apertura, debido al riesgo de pseudomixoma peritoneal.

Abstract
Objective

To report one case of appendiceal mucocele misdiagnosed with an infected urachal cyst and to review their differential diagnosis, treatment and prognosis.

Patient

We report the case of a 74 year-old-male with abdominal pain, fever and dysuria. Hypogastric abscess image in ultrasonography and CT. Percutaneous drainage and antibiotic therapy. Opaque enema, colonoscopy and cystoscopy were normal.

Results

Exploratory laparotomy and resection of a large cecum-fixed mass, independent to the bladder. Appendectomy and cecectomy. Pathology showed an appendiceal mucinous cystoadenoma (mucocele).

Conclusions

Appendiceal mucoceles and urachal cysts are uncommon, mostly asymptomatic. Cystoadenoma or cystoadenocarcinoma mucoceles are large and can reach the midline, confounding with urachal cysts. Diagnosis by ultrasonography and/or CT. Surgical treatment in both, keeping the mucocele intact during operation to avoid the risk of pseudomyxoma peritonei.
