“…Surgical treatments have been indicated for intracanalar osteochondroma, which is associated with myelopathy, [2][3][4][5][6][7]12,13 radiculopathy, 8 insufficiency of the vertebral artery, 25 and neck pain. 2 From various other possible surgical procedures, laminectomy was chosen by a majority of authors.…”

Tetraparesis due to exostotic osteochondroma at upper cervical cord in a patient with multiple exostoses–mental retardation syndrome (Langer–Giedion syndrome)

Study design: Case report of a severe upper cervical cord compression and tetraparesis by a massive cervical exostotic osteochondroma in a patient with multiple exostoses-mental retardation syndrome (Langer-Giedion syndrome; LGS). Objective: To describe this very rare pathological condition and the results of surgical intervention. Setting: Gifu, Japan. Methods: A 23-year-old man was referred to our clinic because of progressing tetraparesis. He had previously been diagnosed with hereditary multiple exostoses and mental retardation. As he had not complained of any symptoms, his family only noticed the tetraparesis after advanced deterioration. His face possessed the pathognomic features of LGS. A postmyelogram CT scan demonstrated an exostotic mass arising from the left-side C2 pedicle with associated severe spinal cord compression. He was diagnosed with LGS. Hemilaminectomy on the left side and resection of the osteochondroma were performed. Results: At 5 years postoperatively, a neurological examination showed the full return of all motor functions. The CT scan revealed no intracanalar recurrence of the tumor. Conclusion: In this case of severe tetraparesis due to cervical osteochondroma, decompression by hemilaminectomy provided excellent results. In patients with LGS and intracanalar osteochondroma, the neurological deficit may be masked by mental retardation. Hence, awareness of this pathological condition will help clinicians diagnose it at an early stage.

“…Therefore, true frequency of spinal localization is probably underestimated [4]. However, some patients with spinal osteochondromas may present with a palpable mass, local pain or symptoms due to neurological or vascular compression [6].…”

Headache due to an osteochondroma of the axis

2004

We reported a case of a 42-year-old man with a 3-year history of headache due to a spinal osteochondroma. Repeated neurological evaluation, including EEG studies and CT of the cerebrum, revealed no pathology. More recently the patient presented with persistent headache and a slight limitation of neck motion. MRI studies of the cerebrum including the cervical spine showed a high cervical extradural tumor. Additional CT angiography showed a bony tumor suspected of being a spinal osteochondroma. An en bloc resection of the tumor was performed; histological evaluation confirmed the diagnosis. Immediately after intervention, all symptoms disappeared. In most patients with a spinal osteochondroma, the lesion causes no symptoms, or symptoms are aspecific. Therefore, there is often a significant delay between initial complaints and the diagnosis, as in the current case.

“…By reviewing over 130 reported cases with osteochondromas, Albrecht et al 1 found that only 1% to 4% of the lesions originate in the spine, and about one half of those spinal osteochondromas are seen at cervical spine. The lesions may stem from any part of a vertebra, including vertebral body, 11,13 pedicle, 6 lamina, 2,12 articular pillar, 7 transverse process, 14 and spinous process, 10 but the most common location is in the posterior elements. Cervical osteochondromas may cause tetraplegia resulting from spinal cord compression, 2,10,11 vertigo, 4 occipital nerve neuralgia, 5 headache, 6 neck and/or shoulder pain, 7,12 hoarseness, 8 cranial nerve palsy, 9 dysphagia, 13 and so forth.…”
