Within the fibrinous exudates, a number of diagnostic clusters of pneumocystis organisms are identified on silver staining. In addition, rare cells show a dark burgundy-red inter-nuclear inclusion, consistent with cytomegalovirus. This is also confirmed by CMV immunohistochemistry. The immunohistochemistry for herpes simplex virus is negative . Characteristic radiographic findings include perihilar distribution of pulmonary infiltrates and frequent sparing of the peripheral lung fields in the early stages. Unusual findings include initial lobar distribution, pleural effusion, and relative sparing of previously irradiated areas of. Radiological features of Pneumocystis jirovecii Pneumonia in immunocompromised patients with and without AIDS. The aim of this study was to compare chest computerized tomography (CT) findings of Pneumocystis jirovecii pneumonia (PCP) in immunocompromised patients with and without acquired immune deficiency syndrome (AIDS) Pneumocystis jirovecii pneumonia is an atypical pulmonary infection, the most common opportunistic infection in patients with acquired immunodeficiency syndrome (AIDS). Classically, PCP was the acronym for pneumocystis carinii pneumonia, but was reclassified as pneumocystis jirovecii
Pneumocystis Pneumonia. There is diffuse, mostly reticular, interstitial lung disease greater at the bases. This is a similar picture to that of congestive heart failure under other clinical circumstances. For these same photos without the arrows, click her Computed tomographic (CT) scans of the chest in 39 patients with Pneumocystis carinii pneumonia (PCP) were reviewed to determine the spectrum and frequency of CT manifestations of PCP. Parenchymal disease was categorized as either bilateral or unilateral, symmetric or asymmetric, and diffuse or patchy Background: Pneumocystis jirovecii pneumonia (PJP) can be challenging to diagnose, often requiring bronchoscopy. 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 The radiographic distribution of Pneumocystis carinii pneumonia was studied in 64 consecutive patients with acquired immunodeficiency syndrome to determine the demographic and clinical factors that might be associated with predominance of the disease in the upper zones of the lungs Radiation pneumonitis Inflammatory and fibrotic changes associated with radiotherapy can cause peripheral ground-glass and consolidations in the area of the radiation therapy field. However, bilateral organizing pneumonia outside the radiation field can also occur, mimicking one of the confirmatory feature of COVID-19
Pneumocystis cariniipneumonia is apparently still rare in the United States, since only seven deaths from this cause have been unequivocally proved. The seventh of these cases, from the John Sealy Hospital, Galveston, Texas, brought to our attention this interesting and serious interstitial plasma-cell pneumonia which we had not heretofore.

Background: Although radiological features of pneumocystis pneumonia (PCP) in non-Acquired Immune Deficiency Syndrome (AIDS) immunocompromised patients have been reported by other authors, there were no studies on the radiological stages of PCP previously. This study aimed to elucidate the radiological stages and prognoses of PCP in non-AIDS immunocompromised patients Pneumocystis Jiroveci Pneumonia Sam A.

Pneumocystis jirovecii pneumonia (PCP) typically presents as an interstitial and alveolar process with ground glass opacities on chest computed tomography (CT). The absence of ground glass opacities on chest CT is thought to have a high negative predictive value for PCP in individuals with AIDS. Here, we report a case of PCP in a man with AIDS who presented to our hospital with subacute. Pneumocystis jirovecii pneumonia (PJP) may present with a very variable pattern of clinical and radiological manifestations, depending on the immunological status of the patient

(2005) Thoracic Imaging. Pulmonary and cardiovascular Radiology. Lippincott Williams & Wilkins 391-993 Discussion Background. Pneumocystis pneumonia (PCP) is caused by the yeast-like fungus Pneumocystis jiroveci (yee-row-vet-zee), named after the Czech parasitologist Otto Jirovec. The organism was previously misclassified as a protozoan and called Pneumocystis carinii.However, use of that nomenclature is now considered incorrect, as Pneumocystis carinii infection only occurs in animals, not humans Pneumocystis carinii pneumonia (PCP) or pneumocystis jiroveci as it is currently named, is an opportumistic infection in immunocompromised patients. PCP used to affect most HIV-infected patients at some point during the course of their disease, but with the new anti-viral drugs it has become less common Single Nodular Opacity of Granulomatous Pneumocystis Jirovecii Pneumonia in an Asymptomatic Lymphoma Patient : Hyun Soo Kim, MD, 1 Kyung Eun Shin, MD, 1 and Ju-Hie Lee, MD 2 1 Department of Diagnostic Radiology, Kyung Hee University Hospital, Seoul 130-702, Korea.: 2 Department of Pathology, Kyung Hee University Hospital, Seoul 130-702, Korea
