Septic Arthritis in an Immunocompromised Patient on Haemodialysis with History of Splenectomy and Sarcoidosis

A male adult in his mid-40s with end-stage renal disease (ESRD) on haemodialysis, with history of splenectomy and sarcoidosis, developed septic arthritis of the knee. Excision and drainage was performed and empiric antibiotics were initiated. Cultures were initially negative without clinical improvement. Eventually, the aerobic synovial fluid culture grew (formerly ). The patient was treated with liposomal amphotericin B and then switched to fluconazole until the infection resolved. This case highlights the less well-recognised association between cryptococcal arthritis and immunodeficiency states like ESRD, splenectomy and sarcoidosis.
