Fig. 3From: Osteoid osteoma of the acetabulum successfully treated with computed tomography-guided resection and ablation using a standard electrosurgical generator: a case reportPatient magnetic resonance images. Coronal T1 (left) and T2 magnetic resonance images (right) showing that the mass was characterized by low intensity on T1 images and high intensity on T2 images (arrows). Magnetic resonance imaging also showed joint effusion (long arrow). Together with clinical findings and computed tomography images, the small lesion was diagnosed as osteoid osteoma of the acetabulumBack to article page
