Rhodococcus equi infection in acquired immunodeficiency syndrome. Computed tomography aspects.

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.
