Seno del segundo arco branquial en un paciente adulto

Abstract

The sinus of the second branchial arch is a secondary alteration of an abnormal development of the branchial arches. The anomalies of the branchial arches include cysts, fistulas, sinuses and ectopic glands. They should be considered in the differential diagnosis of neck masses in adult or pediatric patients. The sinus of the branchial arch accounts for about 30 % of the congenital masses of the neck and is usually diagnosed in the second to third decade of life, with those of the second arch being more common. It presents with nonspecific symptoms. Imaging studies are essential for the diagnosis, classification and surgical management. We present the case of a 67-year-old patient with a clinical history and physical examination of second branchial arch sinus, who required fistulography and computed tomography for adequate characterization. The patient underwent surgery without complications.
