Cryptococcus neoformans presenting as a large pulmonary cavitary lesion in an immunocompetent female

Abstract

Pulmonary cryptococcus is a rare but fatal fungal infection historically associated with Human Immunodeficiency Virus (HIV) and immunosuppression, yet increasingly also being recognized in immunocompetent patients as a result of antiretroviral therapy and improved HIV control reducing HIV-associated cryptococcus in advanced countries. Appropriate management may be delayed if left unrecognized. We present the case of an immunocompetent middle-aged female with nonspecific respiratory symptoms who was found to have a large cavitary lung mass resulting in external compression of the pulmonary vein, ultimately leading to a diagnosis of pulmonary Cryptococcus neoformans. By presenting this case, we hope to elucidate the challenges in diagnosing and managing this fatal disease in timely fashion.
