  • Title: [Radiographic and pathological findings in 4 patients with pulmonary cryptococcosis].
    Author: Hidaka T, Ichinose I, Tamura K.
    Journal: Nihon Kyobu Shikkan Gakkai Zasshi; 1997 Jan; 35(1):129-35. PubMed ID: 9071170.
    Abstract:
    We reviewed the records of 4 patients with pathologically diagnosed pulmonary cryptococcosis to determine whether there was any relationship between radiographic and pathological findings. The underlying disease were diabetes mellitus (patient 1), rheumatoid arthritis treated with glucocorticoids (patient 2), and adultonset T cell leukemia (patients 3 and 4). All radiographs showed multiple nodules, and patchy and localized infiltrates, which progressed to diffuse interstitial infiltration. According to Mark's classification, the pathological findings in patients 1 and 2 showed granulomatous pneumonia, those in patient 3 showed histiocytic pneumonia, and patient 4 had intercapillary cryptococci with no inflammatory response. The granuloma appeared larger in patient 1 than in patient 2. This concurred with the clinical findings, i.e. large granulomas formed in immunocompetent patients, and diffuse pulmonary infiltrates developed in those whose immune systems had been compromised. When a granuloma formed, roentgenograms showed a well defined nodular shadow, with some nodules developing in the cavity. When granuloma formation became unclear, roentgenograms tended to show localized-to-diffuse infiltration, or interstitial shadows.
