question: Emphysematous pyelonephritis (EPN) is a necrotizing gas producing infection of the renal parenchyma that commonly occurs in patients with diabetes. EPN requires early diagnosis and treatment due to the possible life-threatening septic complications. We report a rare case of EPN caused by an unfavorable mixed infection of Candida parapsilosis and Finegoldia magna. To our knowledge, this is the first reported case of EPN caused by Finegoldia magna. A 62-year-old male with diabetes mellitus (DM) presented with abdominal pain, shortness of breath, and nausea in which a diagnosis of septic shock was made due to EPN. Our patient first noticed abdominal pain 3 weeks prior to hospital presentation; however, he avoided getting treatment due to a fear of contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This patient exhibited deterioration and expired after surgical intervention despite uneventful nephrectomy. This case suggests that medical care avoidance behaviors among patients could potentially complicate their clinical course.
