CASE 50 Clinical Presentation 26-year-old man with fever, cough productive of purulent sputum, and hemoptysis Radiologic Findings PA ( Fig. Pneumocystis jiroveci pneumonia: high-resolution CT findings in patients with and without HIV infection. Diagnosis is by clinical and laboratory evaluation for sepsis. Signs may be limited to respiratory distress or progress to shock and death. Onset may be within hours of birth and part of a generalized sepsis syndrome or after 7 days and confined to the lungs. Identifying patients at low risk of PJP may enable better use of non-invasive testing to avoid bronchoscopy while higher probability patients could be prioritized.Ĭomputed tomography Diagnosis PCP PJP Pneumocysitis jirovecii Pneumonia.Ĭatherinot E, Lanternier F, Bougnoux ME, Lecuit M, Couderc LJ, Lortholary O. Neonatal pneumonia is lung infection in a neonate. Where there is clinical suspicion of PJP, the use of CT scan can help determine the probability of PJP. However, multivariable analysis of CT scan findings found that 'increased interstitial markings' (OR 4.3 95%CI 2.2-8.2), 'ground glass opacities' (OR 3.3 95%CI 1.2-9.1) and the radiologist's impression of PJP being 'possible' (OR 2.0 95%CI 1.0-4.1) or 'likely' (OR 9.3 95%CI 3.4-25.3) were independently associated with the final diagnosis (c-statistic 0.75). We used multivariable logistic regression to identify radiographic features independently associated with PJP.Ĭhest x-ray findings poorly predicted the diagnosis of PJP. We created a cohort of patients who underwent bronchoscopy specifically to diagnose PJP and conducted a nested case-control study to compare the radiographic features between patients with (n = 72) and without (n = 288) pathologically proven PJP. Since most patients suspected of PJP undergo imaging, we hypothesized that the findings of these studies could help estimate the probability of disease prior to invasive testing.

Pneumocystis jirovecii pneumonia (PJP) can be challenging to diagnose, often requiring bronchoscopy.
