What are radio manifestations of PCP?

CXR: normal up to 1/4 of pt, most commonly diffuse, bilateral interstitial or alveolar infiltrates, upper lobe infiltrates and pneumothorax may be de novo. less common: lobal infiltrates, cysts, nodules, pleural effusions HRCT: high sensitivity, patchy/nodular ground-glass attenuation (not dx, suggestive of PCP) Gallium-67 nuclear scan: not very used
