PG - 75-77 LID - S1201-9712(18)30034-1 [pii] LID - 10.1016/j.ijid.2018.01.033 [doi] AB - A 67-year-old man presented to the hospital with complaints of fever and cough. He had a past medical history of renal cell carcinoma and had just started treatment with temsirolimus, a mammalian target of rapamycin (mTOR) inhibitor. A 1-week course of antibiotics did not have any effect on his symptoms. A chest computed tomography (CT) scan showed the reversed halo sign (RHS). Organizing pneumonia induced by mTOR inhibitor treatment was initially considered. However, transbronchial biopsy revealed clusters of fungal organisms, suggesting infection with Aspergillus spp. Within just 2 weeks, a CT scan showed drastic enlargement of the cavitary lesion, with multiple newly formed consolidations. The patient was diagnosed with invasive pulmonary aspergillosis. Concomitant treatment with voriconazole and micafungin was started. Two weeks after the initiation of treatment, he became afebrile with gradual regression of the cavitary lesion and consolidations. CI - Copyright (c) 2018 The Authors. Published by Elsevier Ltd..
