Diagnosis With Brief Discussion

Diagnosis
Pneumocystis jirovecii pneumonia (miliary pattern)
Radiologic Findings
Chest PA shows innumerable miliary nodules diffusely seen in both lung fields.
Chest CT shows randomly distributed fine micronodules in both lungs, combined with ground glass opacities and some patchy consolidations in both upper lobes and right lower lobe.
Some nodules seem to show perilymphatic distribution.
Clustered centrilobular nodular ground glass opacity with bronchiectasis in BUL apex and lateral segment of RML. Multifocal small nodular consolidations are also combined.
The patient underwent bronchoscopy, and the bronchial washing fluid was positive for Pneumocystis jiroveci and negative for CMV and TB PCR.
The patient started receiving Bactrim, and the follow-up chest PA about two months later showed complete resolution of pneumonia.
Brief Review
Pneumocystis jiroveci is an important opportunistic pathogen in immunocompromised hosts and especially in AIDS patients. Extensive ground glass opacities, with predilection for upper lobes, is its main radiographic features, and pulmonary cysts of varying sizes is known to be found more so in patients with AIDS. Granulomatous inflammation is known to occur in approximately 5% of patients, usually when immunodeficiency is more limited, seen as a solitary nodule or multiple nodules on CT.
Miliary pattern of Pneumocystis jiroveci pneumonia is very unusual compared with miliary TB, and only a few such cases have been reported. We thought this is an interesting case showing various CT manifestations of Pneumocystis pneumonia.
