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

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.

Managing Kartagener's Syndrome With Type II Respiratory Failure and Left-Sided Pneumothorax During the COVID-19 Pandemic: A Case Report.

Kartagener's syndrome is an autosomal recessive disorder with symptoms varying from chronic sinusitis to bronchiectasis and situs inversus (a congenital condition in which the visceral organs are located in an opposite location). We describe a rare and complicated case of a 40-year-old female patient who presented to the emergency room with significant chest congestion and Kartagener's syndrome. This case demonstrates the value of individualized and proactive care as well as the challenge of managing this illness, particularly when it coexists with type II respiratory failure related to pneumothorax.
