Figure 7a. Parahypothalamic osteolipoma of the tuber cinereum in a 43-year-old woman with headache and blurred vision. (a) Sagittal T1-weighted MR image shows a well-defined high-signal-intensity lesion at the tuber cinereum (arrow). (b) On an axial fat-suppressed T2-weighted MR image, the lesion exhibits suppressed signal intensity. Arrow indicates a markedly hypointense linear structure that is consistent with bone tissue, a finding that was confirmed at surgery.
