Abstract:
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.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
