Joint Pain Undergoes a Transition in Accordance with Signal Changes of Bones Detected by MRI in Hip Osteoarthritis
A 74-year-old woman, 152.0 cm tall and weighing 57.5 kg with no history of OA visited our hospital. At her first visit, she complained of right hip joint pain (P4). Plain radiographs showed OA at KL grading IV (Fig. ). Since then, joint pain has shown repeated remission and deterioration. Recent plain radiographs also showed OA at KL grading IV. MRI was performed at the time of right hip joint pain (P4). MRI showed high signal change in the entire femoral head and acetabulum in T2-STIR (Fig. ).
