Unusual Presentation of Brucellosis in Baker’s Cyst

A 55-year-old diabetic male came with history of left knee pain and swelling for 7 days, fever for 3 days, and no history of trauma. He was complaining of tenderness on the left popliteal fossa, and the surrounding area was red and soft to firm swelling; he was limping, and could not bear weight on the left leg. The ultrasound showed that there was a well-defined heterogeneous hypoechoic cystic lesion. Under aseptic technique, continuous US guidance and local anesthesia, we aspirated almost all the fluid of the left calf collection, which was reported as complicated baker cyst. The patient was put on ciprofloxacin, gentamycin, and doxycycline. The patient was cleared from infectious diseases’ team and discharged after 7 days.
