✓ The authors report on the management of occipital neuralgia secondary to an abnormality of the atlas in which the posterior arch was separated by a fibrous band from the lateral masses, resulting in C-2 nerve root compression. The causes and treatments of occipital neuralgia as well as the development of the atlas are reviewed.

✓ The authors report their experience with 12 cases in which the roots of the sciatic nerve were compressed at the intervertebral foramina by degenerative arthritis (arthrosis) of the posterior facets, and in which foraminotomy and facetectomy brought relief of pain. Patients with disc narrowing, spondylolisthesis, and transitional vertebrae place unusual stress on the posterior facets. This may lead to hypertrophy and the development of marginal osteophytes that project downward with eventual constriction of the intervertebral foramen and entrapment of the nerve root. Such alterations are common in patients over 40, and when found in the presence of unremitting sciatic pain without evidence of a herniated disc or other etiology, a causal relationship must be considered.

✓ The authors report a symptomatic congenitally anomalous ectatic vertebral artery not passing through the transverse foramen of the atlas (C-1), but instead piercing the dura mater below the posterior arch of the C-1 in the atlantoaxial (C1–2) interlaminar space. This occurrence is exceptionally rare, but in this case it was uniquely associated with occipital neuralgia due to vascular compression of the C-2 root. Microvascular decompression was curative. Neuroradiological and surgical findings are presented and their implications discussed.

✓ Two patients presenting with signs and symptoms suggestive of nerve root compression secondary to extradural masses were found to have ligamentum flavum hematomas. Both patients had neurological deficits preoperatively and regained normal function postoperatively. There was no significant antecedent injury in either case. The symptom course was longer than that for spontaneous epidural hematoma. In one case, there was remodeling of bone, initially suggesting either infection or tumor.

✓ Patients with symptomatic L-5 nerve root compression and associated lytic spondylolisthesis are commonly treated by bilateral wide posterior decompression and concomitant fusion, often accompanied by transpedicular instrumentation. More limited surgery aimed solely at the relief of nerve root compression offers the potential for significant relief of radicular pain while avoiding iatrogenic instability, thereby alleviating the need for arthrodesis with its increased surgical morbidity. Nine patients with unilateral radicular symptoms referable to the L-5 nerve root, minimal back pain, and a lytic pars lesion with mild spondylolisthesis underwent unilateral microdecompression on their symptomatic side without associated fusion. All patients obtained relief of radicular pain at both short- and long-term follow-up examination. One patient demonstrated increased back pain and, accordingly, the procedure is now recommended only for patients with no greater than a 25% spondylolisthesis. Unilateral microdecompression without stabilization is an effective and safe method for relieving radicular pain in patients with a lytic pars defect, a mild spondylolisthesis, and minimal back pain. This therapeutic option should be considered in select cases as an alternative to bilateral wide decompression with fusion and instrumentation.

✓ A patient is described who developed an acute, occult, lumbosacral nerve root meningocele following a partial traumatic avulsion of the L-4 and L-5 nerve roots accompanied by fracture of the pelvis and fibula. Almost total functional recovery ensued. The differences between acute and chronic nerve root meningoceles are discussed, as well as the possibility of surgical intervention.

✓ Patients with hemifacial spasm were treated by three different surgical procedures: 1) partial sectioning of the facial nerve just distal to the stylomastoid foramen; 2) selective neurectomy of facial nerve branches; and 3) microvascular decompression. A retromastoid craniectomy with microvascular decompression was most effective in relieving hemifacial spasm and synkinesis. In a postmorten examination on one patient, microscopic examination of the facial nerve, which was compressed by an arterial loop of the posterior inferior cerebellar artery at the cerebellopontine angle, revealed fascicular demyelination in the nerve root. On the basis of surgical treatment, electromyography, and neuropathological findings, the authors conclude that compression of the facial nerve root exit zone by vascular structures is the main cause of hemifacial spasm and synkinesis.

✓ A case of a neurocytoma involving a nerve root of the cauda equina in a 46-year-old woman is reported. The patient presented with a 2-month history of progressive left lower-extremity weakness and pain and decreased ability to walk, as well as complaints of incomplete voiding. A magnetic resonance image revealed a 7-mm oval mass that was located intrathecally and extended from T-12 to L-1 and was adjacent to a nerve root. No lesions were identified at higher vertebral levels. The mass was excised. On histological examination it was found to have classical features of a neurocytoma. To the best of the authors' knowledge, this is the first report of a neurocytoma occurring in that region. A detailed histological description of this case and review of the pertinent literature are provided.
