Abstract
The initial and follow-up chest radiographs of 31 patients with the acquired immunodeficiency syndrome (AIDS) were reviewed to assess the spectrum and frequency of opportunistic pulmonary infections. In our series, the most common pulmonary infections seen on chest films were: Pneumocystis carinii pneumonia (PCP) (n = 17), PCP associated with Cytomegalovirus (CMV) (n = 2), PCP associated with Mycobacterium avium-intracellulare (MAI) (n = 1), Mycobacterium tuberculosis (n = 7), CMV (n = 2), MAI (n = 1) and Cryptococcus neoformans (n = 1). Diffuse or focal interstitial infiltrate is the most common finding in PCP; bilateral focal or multilobar interstitial infiltrates are also frequently observed: they are usually caused by PCP or by PCP associated with CMV. Infiltrating cavitating lesions and multiple interstitial well-defined nodules < 10 mm diameter were seen only in Mycobacterium tuberculosis infections. Normal chest findings and/or pleural effusions were uncommon; no case exhibited pulmonary cysts on initial radiographs. In this retrospective study we emphasize the high incidence of Mycobacterium tuberculosis infections; other pulmonary infections are emerging in AIDS. The X-ray patterns of pulmonary infections in AIDS must be known for a prompt and accurate diagnosis and to plan the appropriate treatment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
