Granulomatosis with polyangiitis (GPA), previously called Wegener's granulomatosis, is a systemic necrotizing vasculitis affecting small and medium-sized vessels and is associated with antineutrophil cytoplasmic antibodies (ANCA). GPA is a systemic disease but can present in a limited form, where the respiratory system is the most commonly involved. Here, we report a case of a 54-year-old African American female who presented with chronic cough and got diagnosed with recurrent right-sided empyema without pneumonia. She underwent a right thoracotomy, and the biopsy showed necrotizing granulomatous inflammation with vasculitis and rare non-necrotizing granuloma, suggesting GPA. Diagnosis of GPA was confirmed by strongly positive anti-proteinase 3 ANCA antibodies. Interestingly, her GPA is a limited form, and she had an excellent recovery after initiation of immunosuppression. Early diagnosis and treatment are critical for better outcomes and survival in GPA.

Cryptococcosis (cryptococcal infection) is a severe life-threatening fungal infection. It is seen worldwide, specifically in immunocompromised, mainly in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS)-infected individuals. Cryptococcal infection can present with meningitis, pneumonia, peritonitis, disseminated cryptococcosis, and cryptococcal fungemia. Here, we report the case of an HIVnegative Caucasian male in his early 50s with liver cirrhosis and asplenia who presented to our hospital with bilateral foot cellulitis and pneumonia. He was eventually diagnosed with disseminated cryptococcosis. Even with appropriate treatment, he developed multiorgan failure and finally expired. The disseminated cryptococcal infection has a very high mortality rate in patients with liver cirrhosis and asplenia. Liver cirrhosis is an independent risk factor, and asplenia is a comorbid condition for cryptococcal infection in HIV-negative patients. Healthcare providers should have a high suspicion of cryptococcosis in these patients. Early testing with cryptococcal antigen assay and initiation of an appropriate antimicrobial regimen can help minimize bad outcomes.

Bilateral adrenal hemorrhage is a very unusual cause of severe adrenal insufficiency and hyponatremia. It can result from trauma, infections, or antiphospholipid antibody syndrome and can be fatal if not diagnosed and treated early. Here, we present a 58-year-old Caucasian man with fatigue, altered sensorium, bradycardia, and hypotension. He denied any abdominal pain, recent trauma, or anti-platelet or anticoagulation agents. His laboratory workup showed hyponatremia with low serum cortisol levels. He was further worked up and underwent computerized tomography (CT) of the abdomen, which showed bilateral adrenal hemorrhage. He was treated with intravenous (IV) steroids followed by oral hydrocortisone and fludrocortisone. His symptoms resolved, and he was safely discharged home. Asymptomatic bilateral adrenal hemorrhage is a sporadic disease, and it should be in the differential diagnosis for disproportionately sick people with other adrenal insufficiency features.

Emphysematous pyelonephritis (EPN) is an acute severe necrotizing form of UTI, with air collection in the renal parenchyma, collecting system, and surrounding tissues. Most common causative organisms are Escherichia coli and Klebsiella. Here we present a 71-year-old Caucasian male with multiple medical problems who was transferred to our ER from a long-term acute care hospital (LTACH) for hematuria, UTI, and septic shock. He is a recipient of a deceased donor renal transplant and was receiving IV amphotericin B for recent cryptococcal meningitis. CT abdomen showed bilateral EPN, including the transplanted kidney. He received aggressive fluid resuscitation, vasopressors, and IV antibiotics and got admitted to the ICU. Unfortunately, his clinical course worsened and required ventilatory support, and his family opted for comfort care because of the high mortality rate. The emphasis of this case report is to investigate immunocompromised patients presenting with UTIs for EPN.
