A 67-year-old man with a past history of pulmonary tuberculosis had been referred to our department complaining of bloody sputum. The chest radiograph on admission showed a cavity in the left upper lung field. Chest CT showed a mass-like fungus ball in the cavity. Pulmonary aspergillosis was diagnosed from the sputum mycology, serum Aspergillus antigen and antibody. Even though 150 mg per day Funguard (micafungin sodium) was given intravenously for 4 weeks, the pulmonary aspergillosis did not improve. Dynamic MRI obtained 20 seconds after intravenous injection of contrast material revealed penetrating vessels in the wall of the cavity, and dilated and proliferative vessels surrounding the cavitary lesion. On the basis of the MRI findings which suggested the risk of massive hemoptysis, we performed left upper lobectomy. The histological specimen revealed dilated pulmonary arteries in the wall of the cavity, corresponding to the penetrating vessels on MRI. This is the first report of radiologic-pathologic correlation using dynamic MRI for pulmonary aspergillosis, to the best of our knowledge.

We studied the clinical features of 59 chronic pulmonary aspergillosis cases (aspergilloma, chronic necrotizing pulmonary aspergillosis) which we experienced in our hospital. To diagnose this disease, X-rays, sputum culture and serologic tests were mainly examined, X-ray findings were a fungus ball type in 47% of cases and thickened wall of a cavity type in 32%. Positive sputum culture found was A. fumigatus 78%, A. niger 13% and A. flavus 2%. Positive rates of serologic tests showed precipitating antibody 81% and antigen 11%; 39% of beta-D glucan exceeded the reference value. As clinical symptoms, bloody sputum and hemoptysis were found at high frequency. Antifungal agents were administered intravenously or topically for treatment, primarily AMPH-B, ITCZ and MCFG. As adjuvant therapy, we administered Ulinastatin which is an elastase inhibitor for use against hemoptysis, and we performed steroid combination for cases considered to be associated with allergy. In all of 6 cases of chronic necrotizing pulmonary aspergillosis which were administered MCFG, X-ray findings improved. A pathogenic factor, elastase was isolated from Aspergillus spp., and we also found the elastase inhibitor from this series. Five of 12 strains of A. fumigatus, and one of 2 strains of A. flavus expressed elastase inhibitory activity when we screened for the culture supernatant of various Aspergillus spp. of a clinical isolate. Elastase inhibitory activity from A. niger was very weak. Culture supernatants from 5 strains of A. fumigatus and one strain of A. flavus were stable for a fever, and human leucocyte elastase was inhibited, but these did not inhibit porcine pancreas elastase. We are aiming at clinical application and plan to continue further study.
