[Three cases of semi-invasive pulmonary aspergillosis occurring in healthy or diabetic individuals].
We encountered three cases of suspected semi-invasive pulmonary aspergillosis, occurring in healthy or diabetic patients. Radiographic findings disclosed cavity formation in 2 of the patients, but only nodular lesions in 1. The beta-D glucan level was elevated in 1 patient, but was within the normal range in the other 2. Morphological findings indicated that all 3 patients had pulmonary aspergillosis. Following the oral administration of FLCZ to 1 patient and ITCZ to the other 2 for about 2 months, the radiographic lesions resolved and hematologic inflammatory reactions cleared up. Gefter et al and Sider et al have defined 2 types of aspergillosis that occur in mildly immuno-compromised or healthy individuals: the semi-invasive type, which destroys pulmonary tissue without vascular invasion and leads to cavity formation; and the locally invasive type, which is characterized by nodular or massive radiographic lesions without cavity formation. Semi-invasive aspergillosis was diagnosed in all 3 of the cases we reported.
