Invasive pulmonary aspergillosis associated with influenza B

Invasive pulmonary aspergillosis (IPA) usually occurs in immunocompromised patients. However, rarely, this infection can occur in normal hosts. This review of the literature identified 13 cases of IPA associated with influenza, of which 12 had influenza A and the type of influenza was not mentioned in the other case. Reported here is a case of IPA, which was associated with influenza B in a 63-year-old immunocompetent woman. Her lungs showed gross invasion and she was treated with itraconazole and amphotericin B. She required mechanical ventilation for about 5 months but recovered completely. This is the first reported case of IPA associated with influenza B.
