case_images: 18-year-old male with a 6-month history of pain in left half of the neck, left shoulder and arm, which was more severe at the night, diagnosed with osteoid osteoma. Anteroposterior cervical X-ray shows radiolucent nodular, well-contoured lesion (arrow) having a mild sclerotic rim located in left neural arch on T1 vertebra.

case_images: In addition, minimal scoliosis whose opening was toward left was noticed on cervical vertebral axis [Figure 1].
case_images: 18-year-old male with a 6-month history of pain in left half of the neck, left shoulder and arm, which was more severe at the night, diagnosed with osteoid osteoma. T2-weighted spinal magnetic resonance imaging in sagittal plane (a) shows signals that belong to heterogeneous hyperintense edema in T1 and T2 vertebrae bodies (black arrow) and paravertebral soft tissues (white arrows) and (b and c) show slightly heterogeneous hypointense osteoid osteoma (black arrows) of a 1.5 cm diameter with hypointensities that belong to millimetric calcific matrix in T1 vertebra left lamina-transverse process junction. Edema is present in paravertebral soft tissues and in pedicules adjacent to the lesion (white arrows).

case_images: There was a rim around the lesion, which was well-contoured and had focus areas void of signal on all MRI series, suggesting millimetric calcification and hypointense sclerosis. There were hypointense signals on T1-weighted series and slightly hypointense signals on T2-weighted series, concordant with intense edema in the paravertebral soft tissues and in the bone marrow of vertebra where the lesion was located and in adjacent vertebrae [Figures 2 and 3].
case_images: 18-year-old male with a 6-month history of pain in left half of the neck, left shoulder and arm, which was more severe at the night, diagnosed with osteoid osteoma. T1- weighted spinal magnetic resonance imaging examination images sagittal plane show (a) signal decreases in T1 and T2 vertebra bodies concordant with edema (black arrows) and cortical sclerosis in C7-T1 spinous processes (white arrows) and (b and c) millimetric hypointense calcific foci within osteoid osteoma in T1 vertebra left lamina-transvers process junction (black arrows) and prominent sclerosis in the bone tissue around it (white arrows).

case_images: 18-year-old male with a 6-month history of pain in left half of the neck, left shoulder and arm, which was more severe at the night, diagnosed with osteoid osteoma. Contrast-enhanced T1-weighted fat suppression spinal magnetic resonance imagingexamination images in sagittal plane show (a) marked contrast enhancement secondary to inflammation-edema in
  paravertebral soft tissues, (b) osteoid osteoma (black arrow) and enhancement in the medullar bone marrow (white arrows) in the vicinity, and c) marked contrast enhancement secondary to inflammation-edema around left brachial plexus roots (white arrows).

case_images: Intense enhancement was observed on the left apical pleural surface and soft tissues around the truncus, on left C7-T2 nerve roots, and paravertebral soft tissues adjacent to the lesion [Figures 4 and 5].
case_images: 18-year-old male with a 6-month history of pain in left half of the neck, left shoulder and arm, which was more severe at the night, diagnosed with osteoid osteoma. Contrast-enhanced T1-weighted fat suppression spinal MRI examination obtained in (a and b) axial plane images show heterogeneous enhancement of osteoid osteoma (black arrows) and marked contrast enhancement (white arrows) around brachial plexus root-truncus on the left, in paravertebral soft tissues and in apex pleural surfaces of lung.

case_images: 18-year-old male with a 6-month history of pain in left half of the neck, left shoulder and arm, which was more severe at the night, diagnosed with osteoid osteoma. Cervicothoracic spinal computed tomography examination after magnetic resonance imaging, (a and b) axial plane images, (c and d) coronal plane reformatted consecutive images show slightly contoured lobule, straight edged osteoid osteoma (black arrows) with calcific foci in T1 vertebra left lamina-transverse process junction.
