Left hip pain and cyst There is moderate to severe osteoarthritis affecting the left hip. A collection of rim-enhancing fluid is seen inferior to the femoral head with a tail that extends towards the femoral neck. This collection measures 2.6 x 1.5 cm in the transverse dimension and 1 cm in the craniocaudal dimension and we suspect this reflects inflammation of the obturator externus bursa. There is relatively little fluid and synovitis within the hip joint itself. There is mild osteoarthritis affecting the right hip.The bone marrow signal of the remaining pelvis is otherwise normal. The remaining musculature of the hip is also normal. The large field-of-view images demonstrate the presence of a right inguinal hernia which may contain a loop of bowel although this is better appreciated on the comparison CT. Note is made of a fibroid uterus, the largest measuring approximately 5.5 cm. Multiple flow-voids within the pelvis adjacent to the uterus may reflect pelvic congestion. There is a small amount of free fluid in the pelvis.
