Objective
To illustrate that Acremonium and Penicillium species are being increasingly recognised in periprosthetic joint infections (PJIs).
Case Report
A 47-year-old male with liver cirrhosis and bilateral hip hemiarthroplasties complained of persistent right hip pain. Bone scan was suspicious for right hip septic arthritis. Laboratory studies revealed an elevated erythrocyte sedimentation rate (ESR; 127 mm/h) and C-reactive protein (CRP; 16.171 mg/L). At surgery caseous necrosis with a yellowish appearance around the hip was noted. Intraoperative cultures were positive for Acremonium and Penicillium species 2 weeks after inoculation. After 4 months of fluconazole monotherapy a successful revision right total hip arthroplasty was performed, the patient is walking without assistance at 1 year after surgery.
Conclusions
We reported a prosthetic hip infection due to Acremonium and Penicillium species. Removal of the prosthesis, antifungal therapy, and re-implantation after 4 months were successful.
