Figure 11: A 20-year-old male with an osteoid osteoma within the radial notch of ulna - patient 6 (A-D). (A) Sagittal STIR, (B) sagittal T1, (C) axial STIR and (D) axial T2-weighted MR images of the right elbow show bone marrow edema within proximal ulna (thick arrows in A, B, and C). This is associated with edema within the adjacent soft tissue (thin arrows in A, C, and D). Note a small focal area of reduced signal intensity on T2 and STIR images (broken arrows in A, C, and D) which raised the suspicion of an osteoid osteoma nidus
