1/43. osteochondroma with compression of the spinal cord. A report of two cases.We report two cases of vertebral osteochondroma. In one patient a solitary cervical lesion presented as entrapment neuropathy of the ulnar nerve and in the other as a thoracic tumour associated with hereditary multiple exostoses producing paraplegia. We highlight the importance of an adequate preoperative evaluation in such patients.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
2/43. Treatment of cervical cord compression, caused by hereditary multiple exostosis, with laminoplasty: a case report.STUDY DESIGN: Case report. OBJECTIVES: Successful excision of the exostosis within the spinal canal. SUMMARY OF BACKGROUND DATA: Myelopathy caused by exostosis within the spinal canal developed in a 13-year-old boy with hereditary multiple exostosis. methods: Spinous process-splitting laminoplasty with an ultrasonic knife was performed to remove the mass and minimize the possibility of postlaminectomy kyphosis. RESULTS: The spinal canal exostosis with cervical cord compression was excised successfully with laminoplasty. After surgery there has been no recurrence of tumor, and the stability of the cervical spine has been preserved. CONCLUSION: This is the first report of laminoplasty as a useful surgical approach for intraspinal exostosis to prevent postoperative cervical instability.- - - - - - - - - - ranking = 1.25keywords = compression (Clic here for more details about this article) |
3/43. osteochondroma of the C5 lamina with cord compression: case report and review of the literature.STUDY DESIGN: Case report of a solitary osteochondroma of the cervical spine causing myelopathy in a 66-year-old woman. OBJECTIVES: To review the relevant literature and describe a highly unusual clinical manifestation of solitary osteochondroma. SUMMARY OF BACKGROUND DATA: Osteochondromas are common benign bony lesions that seldom occur in the axial skeleton. These lesions are more commonly reported with neural compression in cases of hereditary multiple exostoses (Bessel-Hagel syndrome, diaphyseal aclasis). methods: Chart review, review of relevant radiographic examinations and histopathologic specimens, clinical follow-up with examination, and literature review. RESULTS: Manifestation with new neurologic deficit in a 66-year-old patient was singular. CONCLUSIONS: Osteochondromas are unusual in the axial skeleton, and are rarely signaled by neural compression. Occurrence is generally in young adults in the second and third decades. Initial manifestation with a new neurologic deficit in a 66-year-old patient was highly unusual.- - - - - - - - - - ranking = 1.5keywords = compression (Clic here for more details about this article) |
4/43. osteochondroma of the tibia and popliteal artery stenosis.In our department, an osteochondroma of the tibia in a young girl with intermittent claudication of the right leg was treated. Many instrumental examinations were performed in order to exclude an arterial disorder. As the patient shows signs of arterial compression, an operative procedure to remove the exostosis was performed.- - - - - - - - - - ranking = 0.25keywords = compression (Clic here for more details about this article) |
5/43. The natural history of disappearing bone tumours and tumour-like conditions.We describe 27 cases of bone tumours or tumour-like lesions where there was spontaneous regression. The follow-up period was 2.8-16.7 years (average, 7.0 years). Fourteen of these cases were no longer visible on plain radiographs. Histological diagnosis included exostosis, eosinophilic granuloma, fibrous dysplasia, fibrous cortical defect, non-ossifying fibroma, osteoid osteoma and bone island. Most cases began to reduce in adolescence or earlier, although sclerotic type lesions showed their regression in older patients. All lesions thought to be eosinophilic granuloma began to regress after periods of less than 3 months, while the duration of the other lesions showed wide variation (1-74 months). As resolution of the lesions took between 2 and 79 months (mean, 25.0 /- 20.3 months) we consider that the most likely mechanism was recovery of normal skeletal growth control. In exostosis with fracture, alteration of vascular supply may contribute to growth arrest, but not to subsequent remodelling stage. In inflammatory-related lesions such as eosinophilic granuloma, cessation of inflammation may be the mechanism of growth arrest, whilst temporary inflammation may stimulate osteogenic cells engaged in remodeling. In the sclerotic type, growth arrest is a less probable mechanism. necrosis within the tumour and/or local changes in hormonal control, plus remodelling of the sclerotic area takes longer. knowledge of the potential for spontaneous resolution may help in management of these tumour and tumour-like lesions of bone.- - - - - - - - - - ranking = 0.0091381261962304keywords = fracture (Clic here for more details about this article) |
6/43. athletes with lower limb ischaemia.The case of a young healthy sportsman and acute exacerbation of chronic infragenicular pain is presented. Further investigation revealed an obstruction of the tibiofibular trunk due to an osteochondroma, arising from the fibula, which was immediately resected. osteochondroma is observed in 1-2% of the population and may present with vascular complications. In young patients and athletes, leg pain may be of vascular origin due to an entrapment or compression and should always be considered.- - - - - - - - - - ranking = 0.25keywords = compression (Clic here for more details about this article) |
7/43. Radiation-induced osteochondroma of the T4 vertebra causing spinal cord compression.A case of a radiation-induced osteochondroma arising from the vertebral body of T4 in an 18-year-old man is reported. The patient presented with a history of progressive left lower extremity weakness. At 7 years of age, he had undergone resection of a cerebellar medulloblastoma and received adjunctive craniospinal irradiation and systemic chemotherapy. Both CT and MR imaging revealed an extradural mass contiguous with the posteroinferior endplate of the T4 vertebral body. This case indicates that radiation-induced osteochondroma should be considered in the differential diagnosis of patients with symptoms of myelopathy or nerve root compression and a history of radiation therapy involving the spine in childhood.- - - - - - - - - - ranking = 1.25keywords = compression (Clic here for more details about this article) |
8/43. Case report: solitary pelvic osteochondroma presenting with L3 nerve root compression.osteochondroma is the most common benign bone tumor, comprising 40% of benign bone tumors. Typically they are found in adolescents growing on long bones such as the femur or radius and are clinically obvious. Very rarely, osteochondromas grow in the pelvis where they can reach a large size and present in more subtle ways. We describe an unusual case of a solitary osteochondroma in an otherwise healthy 29 year-old male presenting with signs and symptoms of an L3 nerve root compression.- - - - - - - - - - ranking = 1.25keywords = compression (Clic here for more details about this article) |
9/43. A rare giant intracranial osteochondroma.osteochondroma is the most common benign bone tumor. However, intracranial osteochondroma is very rare, which usually arises from the skull base. Origination from the dura and falx occurs only in sporadical cases. To our knowledge, only twelve cases have been reported in English literature. We report a case of giant osteochondroma from the falx cerebri causing external compression on the brain. Radiographic findings, computed tomography and magnetic resonance imaging manifestation with histologic correlation are described.- - - - - - - - - - ranking = 0.25keywords = compression (Clic here for more details about this article) |
10/43. Vascular compression caused by solitary osteochondroma: useful diagnostic methods of magnetic resonance angiography and Doppler ultrasonography.osteochondroma is a common benign bone tumor that sometimes causes vascular complications when the lesion is situated near the knee. Venous complications are seen less frequently. We report two cases of solitary osteochondroma that arose in the distal femur. The patients were an 11-year-old boy and a 16-year-old boy, both of whom were suffering from bone protuberance and lower leg swelling due to congestion. In both patients, magnetic resonance imaging (MRI) revealed dilated popliteal veins at a site distal from the tumors or superficial veins. MR angiography (MRA) showed compressed popliteal arteries, and Doppler ultrasonography revealed weaker blood flow in the dorsalis pedis arteries in the lower leg with the tumor than in the other lower leg. The former patient complained of pain due to swelling in the lower leg, and for this reason the patient underwent resection of the tumor. After resection, both the swelling and the pain were decreased, and Doppler ultrasonography also revealed normal blood flow in the artery. The latter patient had swelling, but no pain, in the lower leg, and accordingly this patient has been followed carefully without resection, since there is always the possibility of irreversible vascular damage caused by osteochondroma, such as arterial or venous occlusion. We present two patients with osteochondroma, both of whom suffered from swelling of the lower leg due to venous compression by the tumor. In both cases, MRI and MRA were useful to show the presence of vascular compression. Doppler ultrasonography could also reveal the blood flow disturbance objectively, even in current osteochondroma cases in which there were no arterial symptoms.- - - - - - - - - - ranking = 1.5keywords = compression (Clic here for more details about this article) |
