[Radiologic aspects of acute invasive pulmonary aspergillosis in 18 immunodepressed patients].
A retrospective study of 18 immunodepressed patients with acute invasive pulmonary aspergillosis enabled the radiologic picture of this increasingly frequent opportunist affection to be described, and different manifestations of the disease as a function of underlying conditions to be determined. Two groups could be distinguished: the first of patients with malignant blood diseases (n = 10) when the "aplasia" factor was dominant; the second of patients without blood diseases (n = 8) when the immunodepression was usually induced by a recent increase in corticoid therapy. Neutropenia was not a finding in any of these patients. The most frequent radiologic finding was single or multiple round excavating foci, these corresponding to zones of bronchopneumonia containing aspergillus filaments with central tissue necrosis forming the "target" lesion. The aplasia was distinguished by the multiplicity of lesions and their excavation following aplasia in the shape of a crescent due to sequestrum formation. Prognosis was related to severity of subjacent lesions. In the 2nd group, lesions could be single and nodular; prognosis was improved by the possibility of reducing immunodepression factors.
