Objective:
To present the computed tomography aspects of Rhodococcus equi pneumonia in seven patients with acquired immunodeficiency syndrome.
Methods:
A retrospective study of the computed tomography scans of seven patients with acquired immunodeficiency syndrome and Rhodococcus equi infection.
Results:
The most common findings were consolidation (n = 7), consolidation with cavitation (n = 6), ground glass opacities (n = 6), peribronchial nodules (n = 4) and centrilobular nodules presenting a "tree-in-bud" pattern (n = 3).
Conclusion:
The most common finding in patients with Rhodococcus equi pulmonary infection and acquired immunodeficiency syndrome was consolidation with cavitation.

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...
