Retroperitoneal, Psoas, and Scrotal Abscesses Due to an Uncommon Organism - Aggregatibacter aphrophilus: Case Report and Review of Literature.

Aggregatibacter aphrophilus is an uncommon cause of vertebral infections and its complications are infrequently seen. We believe ours is the first reported case of scrotal abscess as a complication of vertebral osteomyelitis. We have also reviewed nine cases with complications similar to this report. Epidural abscess is the most commonly found complication, having been reported in six patients, followed closely by psoas abscess, which was seen in five patients. All except one patient underwent surgical drainage, with all patients showing complete resolution of infection.
