RADIOGRAPHIC FINDINGS IN 35 CASES OF PULMONARY INFECTION CAUSED BY RHODOCOCCUS EQUI3
Keywords:
Rhodococcus equi, pulmonary infection, HIVAbstract
Rhodococcus equi(Corynebacterium equi) is able to produce infections not only in animals but also in human being usually in immunosuppressed one. We report 35 cases of pulmonary infection with this organism mainly in patients infected with the human immunodeficiency virus (HIV) and this is the biggest series ever reported.
The most common pulmonary manifestations including area of opacity with cavity 48.72%, area of opacity without cavity 28.21%, other findings were mass with or without cavity, nodule and interstitial infiltration. The lesions involved the lower lobe in 55.26% while the upper lobe involvement was 42.11%. Multiple sites of involvement was noted in 11.43%. Pleural effusion encountered in 22.86%. Pericardial effusion and endo- bronchial lesion were noted in one and two cases respectively.
The course of the disease usually subacute with symptoms of fever, cough, chest pain and hemoptysis of various duration from 1 to 12 weeks.
Rhodococcus equi infection should always be considered in the differential diagnosis of a HIV infected patient with cavitary pneumonia.
