Article Figures & Data
Figures
- Fig 1.
Lateral radiograph of the cervical vertebrae. There is a minimally expansile lesion of the spinous process of C4 vertebra (arrow).
- Fig 2.
Axial nonenhanced CT scan with bone window of the fourth cervical vertebra. Note the thinning of the cortical bone.
- Fig 3.
Sagittal T2-weighted and T1-weighted MR images of cervical vertebrae show the spinous process, unilocular, and homogeneous cystic lesion of the fourth cervical vertebra.
- Fig 4.
Axial T2*-weighted MR image of the fourth cervical vertebra shows homogeneous and hyperintense appearance of the lesion. Note the lack of blood degradation products.
- Fig 5.
Axial postcontrast T1-weighted MR image demonstrates similar signal intensity characteristics as those of precontrast T1-weighted images (not shown) that define nonenhancing lesions.
- Fig 6.
Results of histopathologic examination
A, Chondroid metaplastic foci in the connective tissue surrounding the lesion (hematoxylin-eosin stain ×100).
B, Lamellar and spongy bone fragments containing bone marrow elements (hematoxylin-eosin stain ×40).
C, Mesothelium-like flat endothelial cells line the wall of the simple bone cyst (hematoxylin eosin stain ×400).
