Abstract

46 patients with invasive pulmonary aspergillosis (IPA) were investigated by chest radiographs (n = 46), plain film tomograms (n = 16), CT (n = 8) and MRI (n = 13). Radiologic characteristics of early IPA were nodular or patchy infiltrates in the upper lobes of all patients. Enlargement of the infiltrates and/or development of segmental/lobar consolidations were typical for fully developing IPA. Air crescent signs were seen in 40% of patients during or after bone marrow restitution. CT added additional information by visualisation of small pleural based infiltrates, demonstration of air crescents and identification of halo phenomena. MRI revealed the target character of nodular aspergilomas with hypointense centres and rims fo higher signal intensity. A gadolinium-DTPA rim enhancement could be observed in almost all nodular lesions. Hyperintense areas in nodular and segmental infiltrates on T1-weighted images were interpreted as aging haemorrhage (methemoglobin) in aspergillus-induced haemorrhagic infarcts or in focal parenchymal bleeding.
