A 3-yr-old boy with known chronic granulomatous disease presented with a left-sided chest wall mass. Extensive intrathoracic and extrathoracic aspergillosis was confirmed by CT scan-guided percutaneous biopsy. Initially, he was treated intravenously with liposomal amphotericin and subcutaneous gamma-interferon, but his clinical condition deteriorated over 7 wk of treatment. The amphotericin was therefore discontinued, and itraconazole in an oral suspension was begun. There was progressive clinical improvement after 3 months of this regime, and marked radiologic clearing was apparent after 8 months of treatment. A multicenter trial of this mode of therapy in patients with invasive aspergillosis is indicated.
