Rare Presentation: A Report Of Two Identical Cases With Thoracic Compressive Myelopathy In Down Syndrome.
Atlantoaxial instability, a common finding in patients with Down syndrome (DS), is attributed to laxity of ligamentous structures. Cervical spondylosis identified in these patients has a pathogenesis of ligament laxity and early degeneration compared with the normal population. No cases have been reported showing affection of thoracic or lower levels. ⋯ Degenerative changes of the spine occur earlier in DS, probably due to increased movements across the vertebrae owing to laxity in the ligaments. Routine workup of patients with DS presenting in their adult lives should keep in mind the affection of lower spinal levels. Early identification of thoracic myelopathy and lumbar canal stenosis gives a chance of cure.

We describe the clinical outcomes in patients with aggressive vertebral hemangiomas (AVHs) after total tumor excision and discuss the treatment options for AVHs. ⋯ Low signal intensity on T1-weighted magnetic resonance imaging was observed in all the patients with AVHs. The long-term clinical results of the preoperative transarterial embolization and total tumor excision were satisfactory. The effect of decompressive incomplete tumor excision is temporary for AVHs, and repeated tumor excision may be necessary because of tumor recurrence in the long term. Reliable total tumor excision during the initial surgery is desirable.

Simultaneous ipsilateral complete ophthalmoplegia and multiple cerebral infarctions are very rare, especially secondary to a very rapidly growing, spontaneous dissecting aneurysm in the cavernous segment of the internal carotid artery (ICA). ⋯ This is the first reported case of simultaneous cerebral infarction and complete ophthalmoplegia attributed to a rapidly growing dissecting aneurysm of the cavernous ICA; such aneurysms readily cause thromboembolism. Physicians who treat patients with dissecting aneurysms should carefully monitor aneurysm growth.

Surgery for lumbar disk herniation (LDH) presents an option for patients when conservative measures fail. The objective of this clinical study is to investigate a novel, objective outcome measure in patients undergoing lumbar microdiscectomy. ⋯ The GPi score is a new, objective descriptor of mobility in spinal surgery which can be used to augment traditional subjective outcome scoring surveys such as the ODI. Significant changes are seen in the GPi and its constituent metrics in patients undergoing surgery for LDH.

Paragangliomas are uncommon neuroendocrine tumors, rarely occurring in the lumbar spine. Primary lumbar paragangliomas are prominently vascularized, can present variably, and pose both diagnostic and surgical challenges. We report on a large case series with long-term follow-up and intraoperative footage to characterize the natural history, diagnostic approach, and operative approach to this rare surgical disease. ⋯ Primary lumbar paragangliomas are rare neoplasms of the cauda equina that typically progress slowly but may also present acutely. They are often related to the filum terminale, which should be resected prior to other attachments intraoperatively to prevent displacement of the tumor out of view. Total resection can be curative, and long-term follow-up in this series found no recurrence.
