Quiste broncogénico de localización excepcional que simula una tumoración pancreática / Unusual location of a bronchogenic cyst simulating a pancreatic tumor

Se presenta el caso de una paciente de 37 años, con antecedentes de colangitis aguda y a la que se diagnosticó erróneamente un quiste broncogénico como neoplasia pancreática, en virtud de los datos clínicos y radiológicos. La localización infradiafragmática del quiste broncogénico es rara y, en ocasiones, puede simular un carcinoma pancreático (AU)

We report a 37-year woman with a history of acute cholangitis in whom a bronchogenic cyst was misdiagnosed as a pancreatic neoplasm on the basis of the clinical and radiological findings. Infradiaphragmatic bronchogenic cysts are rare and can sometimes mimic a pancreatic carcinoma (AU)

Basal cell adenocarcinoma is a rare tumor first considered to be a separate entity by the WHO in 1991. The mean age of presentation is 48 years and it does not affect one gender more than the other. It normally follows an insidious course with nonspecific signs and symptoms. We present a case of adenocarcinoma of the lacrimal sac diagnosed at histological study. We show the CT, MRI, and histological findings. We discuss the differential diagnosis and treatment for this tumor.

Adenocarcinoma de células basales del saco lacrimal bien diferenciado. A propósito de un caso / Well-differentiated basal cell adenocarcinoma of the lacrimal sac: a case report

El adenocarcinoma de células basales es un tumor raro y descrito por la Organización Mundial de la Salud (OMS) en 1991 como entidad propia1,2. La edad media de presentación es de 48 años y no muestra predominio sexual. El curso es insidioso con signos y síntomas inespecíficos. Presentamos un caso de adenocarcinoma de saco lacrimal, cuyo diagnóstico se realizó por anatomía patológica. Mostramos los hallazgos de tomografía computarizada, resonancia magnética y anatomía patológica. Se comenta el diagnóstico diferencial y el tratamiento

Estudio mediante técnicas de imagen de las fístulas del seno piriforme / Diagnostic imaging of piriform sinus fistulas

Objetivos. Establecer la utilidad de la ecografía, tomografía computarizada (TC), resonancia magnética (RM) y estudios baritados en el diagnóstico de las fístulas del seno piriforme (FSP). Material y métodos. Se han revisado las historias clínicas y los estudios de imagen de cuatro pacientes de edad pediátrica diagnosticados de FSP. La primera técnica de imagen que se realizó en todos los casos fue la ecografía cervical; a tres se les realizó posteriormente TC con contraste intravenoso y a uno RM; a todos ellos, de forma diferida, se les practicó esofagograma con bario. En todos los casos hubo comprobación quirúrgica. Resultados. En los cuatro pacientes la ecografía permitió identificar la localización de las lesiones en el lado izquierdo, así como la existencia de colecciones heterogéneas en tiroides y tejido peritiroideo. Posteriormente, mediante la TC y la RM se delimitaron las lesiones abscesificadas. El esofagograma con bario demostró la existencia de la FSP en los cuatro casos. Conclusiones. La presencia de un proceso inflamatorio de repetición y de tiroiditis supuradas agudas de localización izquierda debe hacernos sospechar la existencia de FSP. Tanto la TC como la RM son útiles en el estudio de la FSP pero, en nuestra experiencia, la ecografía es la técnica de elección en su valoración inicial y seguimiento evolutivo. Tras el proceso agudo, el esofagograma con bario sigue siendo el principal método diagnóstico del trayecto fistuloso

Objectives. To establish the usefulness of ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and barium contrast swallow studies in the diagnosis of piriform sinus fistulas (PSF). Material and methods. We reviewed the clinical histories and imaging studies of four pediatric patients diagnosed with PSF. Cervical ultrasound was the first imaging study performed in all cases. Three patients subsequently underwent intravenous contrast-enhanced CT examination and one underwent MRI. Barium contrast swallow studies were performed in all patients at a later time. All cases were confirmed at surgery. Results. Ultrasound enabled the lesions to be located on the left side and showed the existence of heterogeneous collections in and around the thyroid glands in all four patients. Posterior CT and MRI studies determined the exact size of the abscessed lesions. Barium contrast swallow studies demonstrated the existence of the PSF in all four cases. Conclusions. The presence of a recurrent inflammatory process and acute suppurating thyroiditis located on the left side should raise suspicions of PSF. Both CT and MRI are useful in the study of PSF; however, in our experience, ultrasound examination is the technique of choice for initial evaluation and follow-up. After the acute process, barium swallow studies continue to be the main method for diagnosing the trajectory of the fistulous tract
