We report a 64 year old man who developed Candida albicans infection following total knee arthroplasty. A two-stage exchange arthroplasty was performed after an initial swab culture grew Acinobacter sp. A scanty growth of yeast was also found from the tissue culture. Intravenous cefuroxime was instituted for six weeks followed by reimplantation four months after the removal. Three weeks after that revision, the prosthesis became infected and a culture of knee aspirate established the diagnosis of Candida albicans infection. Treatment consisted of thorough debridement of the involved joint and oral fluconazole for a year. Infection was never totally resolved and a secondary infection with methicillin resistant staphylococcus aureus then developed. Excision arthroplasty was done at two and a half years after the initial infection. At five years follow-up the infection was quiescent and he had a range of movement of 30 degrees to 70 degrees. Knee brace was used to control the valgus-varus stability.
Paraspinal abscess and spondylodiscitis due to Citrobacter koseri is a very rare condition. We report a remarkable case of Citrobacter koseri bacteraemia complicated by paraspinal abscess and spondylodiscitis in a patient who has successfully been treated in our hospital. Our patient demonstrates one of the common challenges in the practice of infectious disease medicine, wherein an innocuous presentation may and often underlie a serious infection. This case report elucidates to us that the diagnosis of a paraspinal abscess and spondylodiscitis requires a high index of suspicion in at risk patient presenting with compatible signs and symptoms.
