1/42. osteosarcoma arising in a solitary osteochondroma of the fibula.We present a case of osteosarcoma arising in an osteochondroma of the right fibula in a 30-year-old woman. The available radiographic studies of the lesion were not suggestive of malignant transformation. The lesion and underlying bone were excised. Histologic examination showed a conventional high-grade osteoblastic osteosarcoma that focally eroded the fibrocartilaginous cap. The patient received postoperative chemotherapy and shows no evidence of disease 27 months following operation. The occurrence of osteosarcoma in an osteochondroma is an extremely rare event, and only a few cases are on record in the literature.- - - - - - - - - - ranking = 1keywords = cord (Clic here for more details about this article) |
2/42. 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 = 71.479927094749keywords = spinal cord, spinal, cord (Clic here for more details about this article) |
3/42. 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 = 23.954543132241keywords = spinal, cord (Clic here for more details about this article) |
4/42. 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 = 25.614599526084keywords = myelopathy, cord (Clic here for more details about this article) |
5/42. Cervical myelopathy due to an osteochondroma in a 73-year-old female. The oldest case in the literature.An osteochondroma is a common developmental tumor of bone characterized by abnormal peri-physeal ectopic enchondral ossification. This results in a cartilage-capped subperiosteal bony projection, which may be either sessile or pedunculated. These lesions are said to grow until skeletal maturity. The cartilage cap is thought to become thinner as the patient ages beyond skeletal maturity. Apparent growth beyond skeletal maturity may be a sign of malignant conversion, usually to a chondroma. Osteochondromas are usually appreciated in the first decades of life, and are most commonly located in the extremities, usually in the knees, ankles, or wrists. Clinical complaints generally relate to the mass effect of the lesion. Solitary osteochondromas of the axial skeleton are less common and may present with a neurological deficit. We report on such a case, in a woman significantly older than other cases described in the literature.- - - - - - - - - - ranking = 86.458398104337keywords = myelopathy (Clic here for more details about this article) |
6/42. osteochondroma of the thoracic spine and scoliosis.STUDY DESIGN: The case of a 16-year-old patient with an osteochondroma in T11 and scoliosis is reported. OBJECTIVE: To describe the treatment of an osteochondroma with scoliotic deformity and the imaging methods used for the diagnosis. SUMMARY OF BACKGROUND DATA: Osteochondromas arising in the vertebral column are rare. However, spinal involvement is found with some regularity because osteochondromas are among the most common benign tumors of bone. methods: The clinical history, plain radiographs, computed tomography, and magnetic resonance imaging, and pathologic findings of the reported patient were reviewed. The medical literature also was reviewed. RESULTS: The patient was treated with surgery in an attempt to remove the tumor and correct the aesthetic deformity. The results were satisfactory, with an improvement of the thoracolumbar scoliosis from 45 degrees to 18 degrees. CONCLUSIONS: Osteochondromas of the vertebral column may cause scoliosis. Computed tomography and magnetic resonance imaging are necessary for evaluating the origin, size, and characteristics of the tumor. In this case, surgical management involved resection of the tumor and correction of the scoliotic deformity.- - - - - - - - - - ranking = 4.7386357830601keywords = spinal (Clic here for more details about this article) |
7/42. 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 = 97.833162403893keywords = myelopathy, spinal cord, spinal, cord (Clic here for more details about this article) |
8/42. osteochondroma of the cervical spine--a surprising finding in a liver transplanted patient with polyneuropathy and polyradiculitis: case report.BACKGROUND: osteochondroma of the spine is a rare condition. We report a case of a patient with a cervical osteochondroma presenting with a polyneuropathy and polyradiculitis simultaneously. CASE DESCRIPTION: In a liver-transplant patient with progressive neurological deficits a polyneuropathy and a polyradiculitis were diagnosed. Eventually the patient became quadraparetic and an osteochondroma compressing the cervical spinal cord was found. The patient's neurological symptoms markedly improved after gross total tumor resection and antibiotic therapy. CONCLUSIONS: review of the literature reveals this case to be an unusual presentation of a cervical osteochondroma, its diagnosis being delayed because of concomitant neurological diseases.- - - - - - - - - - ranking = 17.869981773687keywords = spinal cord, spinal, cord (Clic here for more details about this article) |
9/42. 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 = 1keywords = cord (Clic here for more details about this article) |
10/42. Cervical osteochondroma as a cause of spinal cord compression in a patient with hereditary multiple exostoses: Computed tomography and magnetic resonance imaging findings.spinal cord compression is a rare but extremely serious complication of hereditary multiple exostoses (HME). Imaging of the spine is important for surgical planning and follow up. We present CT and MR findings in a male patient with HME who developed spinal cord compression from a cervical osteochondroma. Complete recovery was achieved following surgery.- - - - - - - - - - ranking = 90.349908868436keywords = spinal cord, spinal, cord (Clic here for more details about this article) |
