Concurrent emphysematous pyelonephritis, cystitis, and iliopsoas abscess from discitis in a diabetic woman

Emphysematous cystitis, iliopsoas abscess, and pneumorrhachis in an elderly woman: a case report

BACKGROUND

Emphysematous cystitis is a well-described life threatening complication of urinary tract infection, most commonly seen in patients with diabetes and typically caused by gas forming bacterial or fungal pathogens. Pneumorrhachis is the rare finding of gas within the spinal canal, most commonly reported in the context of cerebrospinal fluid leakage secondary to trauma or spinal instrumentation. To our knowledge there is only one other reported case of pneumorrhachis in the setting of emphysematous cystitis.

CASE PRESENTATION

This is a single case report of pneumorrhachis in the setting of emphysematous cystitis. An 82-year-old Asian female patient originally from East Asia, with no prior medical history besides hypertension, presented to hospital with a chief complaint of acute on chronic neck pain and functional decline. Examination revealed nonspecific neurosensory deficits and suprapubic tenderness. Laboratory investigations demonstrated leukocytosis and extended-spectrum beta-lactamase containing Escherichia coli bacteremia and bacteriuria. Computed tomography showed emphysematous cystitis with widespread gas within the cervical and lumbar spinal canal, as well as multiple gas-containing soft tissue collections in the bilateral psoas muscles and paraspinal soft tissues. Despite prompt antimicrobial therapy the patient passed away within 48 hours from septic shock.

CONCLUSIONS

Our case adds to a growing body of literature showing that the spread of air to distant sites, including the spine, may be a poor prognostic indicator in patients with gangrenous intraabdominal infections. This report highlights the importance of recognizing the causes and presentation of pneumorrhachis to facilitate early diagnosis and treatment of potentially life threatening and treatable causes.

Emphysematous pyelonephritis and cystitis: A case report and literature review

This present case report describes a 64-year-old female patient with type 2 diabetes mellitus who also had emphysematous pyelonephritis (EPN) and emphysematous cystitis (EC). Computed tomography revealed well defined emphysematous pyelonephritis and cystitis. Broad-spectrum antibiotic and percutaneous drainage of the right kidney were used as part of a conservative management regimen. The patient achieved clinical recovery and was discharged 12 days after admission. Furthermore, 13 other cases of EPC and EC that were reported between 1962 and 2017 were reviewed and discussed. The overall mortality was 15.4% (two of 13 patients), compared with 25% for EPN alone or 7.4% for EC alone as reported in the literature. The primary pathogen identified in the 13 patients was Escherichia coli (53.8%). All 13 patients were treated with antibiotics.
