A Case Report of Bacteremia Due to a Symptomatic and Rare Lactobacillus Rhamnosus Infected Splenic Hematoma and the Ultimate Treatment Model.

We present the case of a 76-year-old male who presented to our hospital with a rare infection of Lactobacillus rhamnosus. The patient had a suspected urinary tract infection (UTI) secondary to a chronic indwelling catheter; however, when symptoms did not improve on standard therapy, blood cultures revealed the growth of L. rhamnosus. The patient was found via imaging to have a concurrent infectious splenic hematoma, and aspiration confirmed the presence of L. rhamnosus. The patient resided in an area nursing home and was a poor historian; however, it is conceivable that this infection was acquired via diet or from normal gut flora as the patient did not present on probiotic supplementation. In this case report, we present both pharmaceutical and interventional treatment strategies as well as a timeline of treatment for this rarely-seen infection.
