BackgroundVarious types of magnetic resonance imaging (MRI) and computed tomography (CT) findings are used to differentiate malignant vertebral fractures (MVFs) from osteoporotic vertebral fractures (OVFs). The distinguishing ability of any single finding is limited. This study developed a novel scoring system that integrates multiple MRI and CT signs for improved accuracy of differential diagnosis between MVFs and OVFs.MethodsA total of 150 MVFs and 150 OVFs in thoracolumbar vertebrae were analyzed. MRI and CT images were obtained within 2 months of the probable time of fracture. The sensitivity and specificity of 15 MRI and CT image findings were evaluated. A stepwise discriminant analysis using these signs as variables was used to create a scoring system to differentiate MVFs from OVFs.ResultsAll 15 image findings had strong specificity and moderate sensitivity. Seven MRI and three CT image findings were selected and assigned integral values in the final scoring system. A total score of 4 or greater points indicated MVF, whereas a total score of 3 or fewer points indicated OVF. The classification accuracy was 98.3% in the test set.ConclusionsThis novel scoring system using MRI and CT radiologic findings to differentiate MVFs from OVFs in Chinese patients was efficient with high accuracy and good applicability.

Objective Spinal osteochondromas are rare, and approximately less than 5% occur as spinal lesions. We report the case of a solitary osteochondroma of the spine and review and update the literature on spinal osteochondroma, including surgical treatment and subsequent results. Case Description A 73-year-old female patient complained of a 10-year history of back pain and a 4-year history of right-side lower extremity radiating pain with paresthesia. Computed tomography and magnetic resonance imaging (MRI) revealed a bony mass arising from the inferior articular process (IAP) of L3, presenting with features of compressive spinal stenosis at the L3–L4 level. The treatment strategy included the complete marginal excision of the lesion through the posterior approach, as well as complete decompression of the spinal canal and nerve roots. The patient’s symptoms resolved after surgery, and histopathological examination identified the lesion as an osteochondroma. Review Results This review study included 168 solitary osteochondroma cases. The most commonly involved spinal level was cervical (51.8%), and the most frequent spinal anatomic column involved was the posterior column (70.8%). Radiculopathy accounted for 30.3% of all cases, myelopathy accounted for 31.0%, and 7.7% exhibited both symptoms simultaneously. The recurrence rate was 6.0%. Conclusion Computed tomography and MRI can effectively diagnose spinal osteochondroma, and surgical treatment can effectively improve clinical outcomes. In almost all symptomatic cases, the best treatment is marginal excision of the tumor. Complete resection of the cartilaginous cap of the tumor is especially important to prevent recurrence.

“…The most concerning complication of osteochondromas is malignant transformation, fortunately a rare complication. Chondrosarcoma of the spine represents 4–10% of all chondrosarcomas and 12% of all malignant tumors of the spine [ 15 ]; the frequency of degeneration is estimated at about 1% in solitary spinal osteochondromas [ 16 ]. Altay et al [ 12 ] in a retrospective analysis of 627 cartilage-forming tumors revealed a rate of malignant transformation for solitary osteochondromas of 4,2% and a higher rate for multiple osteochondromas, namely, 9,2%.…”

We present a case of a 5th Lumbar Vertebra (L5) spinous process osteochondroma as a rare cause of lumbar pain in an old patient. A 70-year-old male presented with progressive and disabling lower lumbar pain. Tenderness over the central and left paraspinal area of the lower lumbar region and a palpable mass were evident. CT scan showed a mass arising from the spinous process of L5. Marginal resection of the tumor was performed through a posterior approach. The histological study revealed an osteochondroma. After surgery, pain was completely relieved. After one year there was no evidence of local recurrence or symptoms. Osteochondromas rarely involve the spine, but when they do symptoms like pain, radiculopathy/myelopathy, or cosmetic deformity may occur. The imagiologic exam of election for diagnosis is CT scan. When symptomatic the treatment of choice is surgical resection. The most concerning complication of osteochondromas is malignant transformation, a rare event.
