Diverticulitis apendicular, reporte de un caso

Objetivo: Presentar un caso de diverticulitis apendicular y compararlo con la literatura actual. Material y M étodo: Registro clínico de un paciente que ingresa a urgencias del Hospital Padre Hurtado, incluyendo cuadro clínico, imagenología, manejo quirúrgico y anatomía patológica. Resultados: Paciente se presenta con cuadro de dolor abdominal atípico, con imagen sugerente de apendicitis diverticular. En pabellón se logra completar apendicectomía laparoscópica con buena evolución posterior. Al estudio patológico se confirman características histológicas de diverticulitis perforada apendicular. Discusión: Se presenta un cuadro clínico que se condice con lo descrito en la literatura actual, aportando imágenes características, tanto de radiología como histopatología. Conclusión: Debido a su mayor riesgo de perforación y mortalidad, la diverticulitis apendicular es una patología que debe considerarse en los diagnósticos diferenciales de dolores abdominales atípicos, en hombres mayores de 30 años, especialmente con los hallazgos imagenológicos característicos.

Objective: To present a clinical case of appendiceal diverticulitis and compare it to contemporary literature. Material and Method: Clinical record of a patient who attends the emergency service of Hospital Padre Hurtado, including clinical presentation, image studies, surgical management and histopathology studies. Results: A patient presents with atypical abdominal pain, image studies suggest appendiceal diverticulitis. Laparoscopic appendectomy was performed with optimal postoperative results. Pathological biopsy studies confirm histological characteristics of a perforated appendiceal diverticulitis. Discussion: A clinical case is presented, which correlates well with contemporary literature of the subject. We provide characteristic image and histopathological studies. Conclusion: Due to its higher perforation rate and mortality, appendiceal diverticulitis is a pathology which must be considered in the differential diagnosis of atypical abdominal pain, in males over 30 years old, especially with characteristic image studies.

Vasculitides are a broad group of diseases that can involve any kind of vessel in any organ. These can be classified according to the size of the affected vessels. The most used classification categorizes them in small, medium, and large vessel vasculitis. Large vessel vasculitis can be further divided in Takayasu arteritis and giant cell arteritis which can sometimes be indistinguishable, even with biopsy. Radiology plays an important role identifying distribution patterns and disease extension18. Fluorine-Fluorodeoxyglucose (FDG) PET-CT shows increased vessel wall FDG uptake in patients with active large vessel vasculitis. Multiple studies show that FDG PET-CT helps to identify the anatomic structures with the disease, as well as evaluate its progression with a high sensibility and specificity in non-treated patients with large vessel vasculitis.
