Prostatic Abscess by Morganella morganii

We describe a case of a prostatic abscess (PA) caused by <i>Morganella morganii</i> (<i>M. morganii</i>). The patient was a 71-year-old immunocompetent man who was hospitalized due to lumbar surgery. A urethral catheter was placed perioperatively. On postoperative day (POD) 6, the patient developed a fever of 38.5°C, elevated inflammatory markers including leukocytosis and C-reactive protein, and pyuria. Blood and urine cultures were positive for <i>M. morganii</i>. Contrast-enhanced computed tomography revealed a hypodense area in the prostate, consistent with PA. The patient was treated with levofloxacin, and his symptoms resolved by POD 11. He was discharged on POD 27 with no signs of recurrence. PA can exhibit diverse, nonspecific symptoms, necessitating clinical suspicion and thorough diagnostics. Identifying <i>M. morganii</i> as the causative agent highlights the need to consider atypical pathogens in postoperative or nosocomial cases, especially in patients with urinary catheters. Further research is needed to explore the pathogenic mechanisms and optimal management of PA caused by uncommon organisms like <i>M. morganii</i>, emphasizing that early detection and tailored treatment are vital for improving patient outcomes and reducing complications.
