The computed tomographic findings in benign disease of the vertebral column

Aggressive spinal haemangiomas: imaging correlates to clinical presentation with analysis of treatment algorithm and clinical outcomes

“…11 On CT imaging, typical haemangiomas show characteristic thickened trabeculae and interposed fat yielding a "honeycomb" appearance on axial images and a striated appearance on sagittal and coronal reconstructions, akin to their classical appearance on conventional radiography. 11,12 Typical MRI findings of vertebral haemangiomas include T1 and Figure 2. A 24-year-old male with extensive lumbosacral aggressive haemangioma.…”

Primary Tumors of the Spine in Children – Natural History and Management

“…A malignant de generation occurs in 10% of osteochondromas. Plain radiographs may be unrevealing because the cartilaginous cap is radiolucent [59,70], The CT scan shows a smooth, round lesion with Hecks of calcification and no enhance ment. Hereditary multiple exostoses are inherited as au tosomal dominant with full penetrance.…”

“…Hemangioma accounts for 10-12% of tumors found at necropsy, making it one of the most common spinal tumors [59], The majority of lesions are solitary, but in about one-third of cases multiple vertebral involvement is found. They are usually asymptomatic unless secondary cord compression occurs or hemorrhage takes place [30,39], Hemangiomas consist of mature, thin-walled vessels of varying size in cavernous patterns.…”

Lumbar Spinal Osteoblastoma Mimicking a Dumbbell Radicular Schwannoma

“…Atypical features may occur in osteoblastomas with a more malignant course [11] . The differential diagnosis includes osteoid osteoma, osteosarcoma, aneurysmal bone cyst and giant cell tumor [15,16,23] . Histologically there is no difference between osteoblastomas and osteoid osteomas, although an osteoid osteoma has a more densely sclerotic osteoid nidus with rare multinucleated giant cells [4,6,17,22] .…”

“…Osteo sarcoma is characterized by numerous mitotic fi gures, cellular atypia and a thick osteoid, woven bone. Giant cell tumors rarely involve the spine, occurring mostly in the vertebral body rather than in the posterior elements [16] , while aneurysmal bone cyst has a similar anatomical location to osteoblastoma and appears on MRI as a well-defi ned mass with multiple cystic spaces [19] .…”
