Hip pain drainage Note that the examination is limited by inability to optimally position the patient, and the patient's body habitus, and by motion artifact.Within the posterior lateral subcutaneous tissues of the left hip is an ill-defined rim-enhancing mixed air and fluid collection measuring approximately 14 x 7.8 x 13 cm in the greatest transaxial and craniocaudal dimensions. This collection extends to the posterior skin surface and abuts the lesser trochanter which demonstrates marrow signal intensity consistent with osteomyelitis. Additional areas of abnormal marrow signal intensity are identified within the left posterior superior acetabulum and left inferior pubic ramus representing additional areas of acute/chronic osteomyelitis.There is a moderate-sized joint effusion. Marked edema of the left pelvic musculature is also present particularly the obturator internus and gluteus medius.
Septic arthritis of the left hip with associated subcutaneous abscess and chronic osteomyelitis.
