Statistics

Organizing pneumonia is an uncommon lung disease with a wide variety of radiologic findings, few of which have been discussed in the literature. We performed high resolution computed tomography on 34 patients with a histological diagnosis of organizing pneumonia and studied the images they presented. Twenty-five of the cases were idiopathic and 9 secondary. The findings observed were parenchymal consolidation (76%), ground glass opacity (59%), bronchial dilatation (53%), centrilobular nodules (35%), septal thickening (23%), halo sign (15%), and reversed halo sign (12%). Secondary cases presented more findings of septal thickening and fewer complete remissions.

Key words:
High resolution computed tomography
Organizing pneumonia
Bronchiolitis obliterans organizing pneumonia
Reversed halo sign

Laneumonía organizada es una enfermedad pulmonar poco frecuente, con gran variabilidad en los hallazgos radiológicos, de la que hasta el momento existe un escaso nümero de casos en la mayoría de los estudios publicados en la bibliografia.

Hemos estudiado mediante tomografía computarizada de alta resolución 34 casos con diagnóstico histológico establecido de neumonía organizada valorando los diferentes patrones de presentación. De estos casos, 25 fueron idiopáticos y 9 secundarios. Los hallazgos observados fueron: consolidaciones parenquimatosas (76%), vidrio deslustrado (59%), dilataciones bronquiales (53%), nódulos centrolobulillares (35%), engrosamientos septales (23%), signo del halo (15%) y signo del halo invertido (12%). Se observó una mayor presencia de engrosamientos septales y un menor número de remisiones completas en los casos secundarios.

Palabras clave:
Tomografía axial computarizada de alta resolución
