Spinal Osteoid Osteoma Revealed by Radiculopathy: Case Report and Literature Review

(A) Axial gadolinium-enhanced fat-suppressed T1-weighted magnetic resonance imaging showing the low-signal intensity lesion (white arrow), centered by a high-intensity round lesion which has strong enhancement, and edema in the surrounding bone marrow (*). (B) Axial T2-weighted magnetic resonance imaging of L5 vertebrae showing a low-signal intensity lesion of the right transverse process, with high-signal intensity peripherally (*) and heterogeneous signal intensity centrally (white arrow). (C) Computed tomography scan showing the lesion arising from right transverse process of L5 vertebrae, revealing the nidus (white arrow) surrounded by dense sclerotic bone in its periphery.
