Brevundimonas diminuta Bacteremia in a Case of Adrenal Insufficiency: A Case Report and Literature Review

<i>Brevundimonas diminuta</i> is an uncommon Gram-negative bacteria rarely isolated from clinical samples. There are few reports of infections caused by this microorganism, especially in immunocompromised patients. We present a case of a 69-year-old male with a history of adrenal insufficiency who presented with <i>B. diminuta</i> bacteremia. The patient's immunocompromised state, resulting from chronic corticosteroid use, likely predisposed him to this rare infection. The limited number of reported cases highlights the need for awareness of this pathogen, especially in vulnerable populations. To the best of our knowledge, this is the first case report of a <i>B. diminuta</i> infection in a patient with bacteremia in the setting of adrenal insufficiency in the United States.
