Abstract
PurposeTo analyze the clinical and radiological characteristics of AIDS related pneumocystis jiroveci infection, pneumocystis pneumonia (AIDS-PCP). MethodsA total of 15 patients with AIDS-PCP was recruited, 14 males and 1 female. All clinical and CT data were collected with all CT images retrospectively analyzed by two senior radiologists who are blind to patients' clinical diagnosis. ResultsThe radiological findings were categorized into 4 types: (1) Ground-glass opacities in 14 cases (93%), with diffuse distributed in bilateral lungs; (2) Interstitial infiltrations in 11 cases (73%), which mainly distributed in lower lobes close to pleura; (3) Irregular patchy densities distributed along the bronchus in 3 cases (20%). (4) Irregular patchy densities with cavity in one case of AIDS-PCP coinfected with Aspergillus infection. Other cases also presented with enlarged mediastinal and axillary lymph nodes, pneumothorax, and pericardial effusion. ConclusionThe radiological findings of AIDS-PCP varies from ground-glass opacifications to interstitial changes, and the definitive diagnosis should be made by combination of clinical data.
