Empleo de patrones de imagen en la identificación de metástasis cervical mediante tomografía computarizada en tumores de cabeza y cuello
Objetivo Evaluar la seguridad diagnostica que proporcionan las imagenes de tomografia computarizada (TC) para identificar la extension regional de tumores de cabeza y cuello (CC). Pacientes y metodo Se efectuo TC a 86 pacientes diagnosticados de neoplasia de faringe y/o laringe que despues fueron intervenidos, con un total de 142 vaciamientos ganglionares. En el estudio de imagen se consideraron los siguientes parametros radiologicos para sospechar afeccion ganglionar: tamano de la adenopatia > 10-11 mm, margenes mal definidos, necrosis central, forma esferica, realce capsular y agrupacion de tres o mas adenopatias. Resultados El 48,5 % de los vaciamientos resultaron N+. La sensibilidad y l…
[Use of imaging criteria to identify cervical metastases using CT scans in head and neck tumours].
Abstract Objective To assess the diagnostic certainty of CT images to identify regional spread of head and neck tumours. Patients and method A CT study was performed on 86 patients with neoplasms in the larynx and/or pharynx. After this, surgical dissection was performed for 142 neck sides. In the imaging study the following parameters were considered for all patients before suspecting malignant nodes: size of adenopathy bigger than 10–11 mm, irregular borders, central necrosis, spherical shape, capsular enhancement, and presence of groups with 3 or more lymphadenopathies. Results 48.5% of dissections were N+. Sensitivity and specificity for physical examination were 59% and 82%, respective…
