Abstract
BackgroundAspergillosis is a serious infection particularly affecting the immunodeficient host. Its co-infection with tuberculosis and cytomegalovirus has not been reported before. Embolic events are well recognized with aspergillous endocarditis and aortitis. Splenic abscess is a rare serious complication of disseminated aspergillosis and is difficult to treat. We report the first case of multiple embolic events and splenic abscess in a patient with pulmonary aspergillosis and cytomegaloviral and tuberculous co-infection, without endocarditis or aortitis.Case presentationThirty-year-old male presented with fever and non-productive cough while on glucocorticoids for glomerulonephritis. He was found to have pulmonary aspergillosis and subsequently developed bilateral lower limb and cerebral fungal emboli and fungal abscess in the spleen. He had IgM and B cell deficiency and cytomegalovirus (CMV) and tuberculous co-infections. He recovered after prolonged course of antimicrobials, splenectomy and cessation of glucocorticoid therapy which also lead to the resolution of immune deficiencies.ConclusionThis report illustrates rare combination of B and T cell suppressive effects of glucocorticoids leading to co-infections with CMV, Mycobacterium tuberculosis and Aspergillus and systemic fungal embolization from pulmonary aspergillosis.

Summary
This case highlights several features of interest. Our patient developed multiple fungal emboli from a pulmonary focus of aspergillosis, a phenomenon not described before. The patient had a severe B cell and IgM deficiency, which reversed after discontinuation of glucocorticoids. This effect has not been described before and we highlight the need for further studies on effects of glucocorticoids on human immune system. This case illustrates the importance of judicious use of glucocorticoids being aware of their wide range of effect on human immune system.
