[THE COMPUTED TOMOGRAPHIC PATTERNOF EARLY MANIFESTATIONS OF PULMONARY ASPERGILELSIS IN IMMUNOCOMPROMISED PATIENTS].

Twelve (20%) of 61 patients were found to have centrolobularly located Y-shaped structures or tree-in-bud or toy man patterns in a few lung lobes. In their orthogonal sections, they were presented as centrolobularly located nodular shadows, which is a direct X-ray sign of bronchiolitis. Our studies allow us to consider circumscribed bronchiolitis to be a valid sign of the early manifestations of pulmonary aspergillosis in hematological cancer patients in the presence of recurrent deep myelotoxic agranulocytoses.
