Reversible pulmonary uptake and hypertrophic pulmonary osteoarthropathic distribution of technetium-99m methylene diphosphonate in a case of Pneumocystis carinii pneumonia.
Diffuse pulmonary deposition of [99mTc]methylene diphosphonate (MDP) as well as abnormalities characteristic of hypertrophic pulmonary osteoarthropathy have been observed in a patient with Pneumocystis carinii pneumonia (PCP). The findings of the bone scan together with those in the corresponding scintigraphy, and roentgenograms of the chest and skeletal structures are presented. Parallel reversal of [67Ga]citrate and [99mTc]MDP pulmonary uptake with specific treatment for and clinical resolution of PCP implies a causal relationship. Topics: Adult; Humans; Lung; Male; Osteoarthropathy, Secondary Hypertrophic; Pneumonia, Pneumocystis; Radionuclide Imaging; Technetium Tc 99m Medronate | 1989 |
[Aerosol pulmonary scintigraphy. A new test in the diagnostic strategy of pneumocystis carinii pneumonia in patients with acquired immunodeficiency syndrome].
In eleven patients with AIDS and suspected Pneumocystis carinii pneumonia we measured the pulmonary clearance and half-life of aerosolized 99m Tc-DTPA (diethylenetriamine pentaacetate). We correlated the half-life with gallium scans and bronchoalveolar lavages. In all nine patients with Pneumocystis, this half-life was shorter than normal value, documenting a significant increase of lung epithelial permeability (p less than 0.001). Six of these 9 patients had abnormal gallium scans. However, in two patients with normal chest X-rays, PaO2 and gallium scans, only the reduced half-life of 99mTc-DTPA evidenced acute lung disease. After treatment, the results of the DTPA half-life correlated with the presence or absence of Pneumocystis. This method is, therefore, a sensitive initial diagnostic test in patients with suspected Pneumocystis pneumonia. A short half-life should prompt bronchoalveolar lavage even when PaO2 and/or chest X-rays and gallium scans are normal.
