✓ The authors present the case of a 60-year-old woman with a neck lipoma that developed dumb-bell extradural extension, causing radiculopathy. To the best of the authors' knowledge, this is the first report of a lipoma originating in the neck with dumb-bell extradural extension through the intervertebral foramen and into the spinal canal. The lipoma was first excised from the foramen via a posterior approach to allow decompression of the nerve roots. The remaining lipomatous tissue was then resected via an anterior approach to avoid the region around the vertebral artery.

✓ Five patients with typical cervical myeloradiculopathy caused by focal cervical spinal stenosis are presented. Dorsal intrusions into the spinal canal by hypertrophied apophyseal joints and thickened laminae resulted in cord and nerve root compression. Minor spondylotic changes were present in the floor of the spinal canal. Laminar decompression with foraminotomy and facetectomy relieved the patients of their symptoms. An anterior approach should not be considered in the management of this disorder. Our findings of severe apophyseal arthrosis with lesser degrees of associated spondylosis are similar to those described in anatomical studies by other authors. While uncommon, myelopathy caused by dorsal compression of the spinal cord and nerve roots deserves specific mention so that therapy can be directed to the proper quadrants of the spinal canal wherein the significant pathology is located.

Object. Von Hippel—Lindau (VHL) disease is an autosomal-dominant neoplastic syndrome with manifestations in multiple organs, which is evoked by the deletion or mutation of a tumor suppressor gene on chromosome 3p25. Spinal hemangioblastomas (40% of VHL disease—associated lesions of the central nervous system) arise predominantly in the posterior aspect of the spinal cord and are often associated with an intraspinal cyst. Rarely, the tumor develops in the anterior aspect of the spinal cord. Ventral spinal hemangioblastomas are a surgical challenge because of difficult access and because vessels feeding the tumor originate from the anterior spinal artery. The goal of this study was to clarify whether an anterior or posterior surgical approach is better for management of hemangioblastomas of the ventral spinal cord. Methods. The authors performed a retrospective analysis of clinical outcomes and findings on magnetic resonance (MR) imaging studies in eight patients (two women and six men with a mean age of 34 ± 15 years) who underwent resection of ventral spinal hemangioblastomas (nine tumors: five cervical and four thoracic). Two surgical approaches were used to resect these tumors. A posterior approach was selected to treat five patients (laminectomy and posterior myelotomy in four patients and the posterolateral approach in one patient); an anterior approach (corpectomy and arthrodesis) was selected to treat the remaining three patients. Immediately after surgery, the ability to ambulate remained unchanged in patients in whom an anterior approach had been performed, but deteriorated significantly in patients in whom a posterior approach had been used, because of motor weakness (four of five patients) and/or proprioceptive sensory loss (three of five patients). This difference in ambulation, despite significant improvements over time among patients in the posterior access group, remained significant 6 months after surgery. In all cases, MR images revealed complete resection of the tumor and in five patients significant or complete resolution of the intramedullary cyst was demonstrated (present in six of eight patients). Conclusions. The outcomes of these eight patients with hemangioblastomas of the ventral spinal cord indicate that both immediate and long-term results are better when an anterior approach is selected for resection.

✓ The authors report two cases of patients with lumbar ossification of the posterior longitudinal ligament (OPLL). One patient underwent surgery via the single posterior approach, and the other patient underwent combined anterior—posterior surgery. The authors consider the anterior approach for excision of the ossified lesion to be the most reasonable for treatment of lumbar OPLL. It is extremely important, however, to select the surgical procedure according to the individual patient's condition.

✓ The treatment of spinal intramedullary arteriovenous malformations (AVMs) with a diffuse-type nidus that contains a neural element poses different challenges compared with a glomus-type nidus. The surgical elimination of such lesions involves the risk of spinal cord ischemia that results from coagulation of the feeding artery that, at the same time, supplies cord parenchyma. However, based on evaluation of the risks involved in performing embolization, together with the frequent occurrence of reperfusion, which necessitates frequent reembolization, the authors consider surgery to be a one-stage solution to a disease that otherwise has a very poor prognosis. Magnetic resonance (MR) imaging revealed diffuse-type intramedullary AVMs in the cervical spinal cords of three patients who subsequently underwent surgery via the posterior approach. The AVM was supplied by the anterior spinal artery in one case and by both the anterior and posterior spinal arteries in the other two cases. In all three cases, a posterior median myelotomy was performed up to the vicinity of the anterior median fissure that divided the spinal cord together with the nidus, and the feeding artery was coagulated and severed at its origin from the anterior spinal artery. In the two cases in which the posterior spinal artery fed the AVM, the feeding artery was coagulated on the dorsal surface of the spinal cord. Neurological outcome improved in one patient and deteriorated slightly to mildly in the other two patients. Postoperative angiography demonstrated complete disappearance of the AVM in all cases. Because of the extremely poor prognosis of patients with spinal intramedullary AVMs, this surgical technique for the treatment of diffuse-type AVMs provides acceptable operative outcome. Surgical intervention should be considered when managing a patient with a diffuse-type intramedullary AVM in the cervical spinal cord.

✓ Transluminal angioplasty for hemodynamically significant stenosis (> 70%) involving the posterior cerebral circulation is now being performed by the authors in selected cases. A total of 42 lesions affecting the vertebral or basilar artery have been successfully treated by percutaneous transluminal angioplasty techniques in 41 patients. The lesions involved the proximal vertebral artery in 34 cases, the distal vertebral artery in five, and the basilar artery in three. Patients were examined clinically at 1 to 3 and 6 to 12 months after angioplasty. Three (7.1%) permanent complications occurred, consisting of stroke in two cases and vessel rupture in one. There were four (9.5%) transient complications (< 30 minutes): two cases of vessel spasm and two of cerebral ischemia. Clinical follow-up examination demonstrated improvement of symptoms in 39 cases (92.9%). Radiographic follow-up studies demonstrated three cases (7.1 %) of restenosis involving the proximal vertebral artery; two were treated by repeat angioplasty without complication, and the third is being followed clinically while the patient remains asymptomatic. In patients with significant atherosclerotic stenosis involving the vertebral or basilar artery territories, transluminal angioplasty may be of significant benefit in alleviating symptoms and improving blood flow to the posterior cerebral circulation.

✓ Hemangiopericytoma is a vascular neoplasm consisting of capillaries outlined by an intact basement membrane that separates the endothelial cells of the capillaries from the spindle-shaped tumor cells in the extravascular area. These neoplasms are found in soft tissues but have rarely been shown to involve the spinal canal. This is a report of three such cases. Surgical removal of the tumor from the spinal canal was technically difficult. A high risk of recurrence has been reported but in these three cases adjunctive radiotherapy appeared to be of benefit in controlling the progression of the disease. These cases, added to the six cases in the literature, confirm the existence of hemangiopericytoma involving the vertebral column with extension into the spinal canal. This entity should be included in the differential diagnosis of lesions of the spinal canal. The risk of intraoperative hemorrhage should be anticipated.

✓ Deliberate occlusion of the basilar or vertebral arteries was performed in 201 patients with intracranial aneurysms, where the aneurysmal neck could not be clipped directly. The aneurysms arose from the basilar apex in 83 cases, the basilar trunk in 46, the vertebrobasilar junction in 35, and the vertebral artery in 37; 87% of the aneurysms were classified as giant lesions (> 2.5 cm). There were 85 upper basilar occlusions, 41 lower basilar occlusions, 29 bilateral vertebral occlusions, and 48 unilateral vertebral artery occlusions. The clinical follow-up period varied from 1 to 23 years, with a mean of 9.5 years. Overall long-term results were excellent in 68% of the patients, good in 5%, and poor in 3%; 24% died. Clinical outcome varied according to aneurysm site; excellent or good results were achieved in 64% of the patients with basilar apex, 76% with basilar trunk, 74% with vertebrobasilar junction, and 87% with vertebral artery aneurysms. Clinical outcome also varied depending on preoperative grade: 86% of the patients with an excellent presenting grade achieved excellent results. The size of the posterior communicating arteries was a good predictor of tolerance to basilar artery occlusion (p < 0.05). Successful aneurysm thrombosis was achieved in 78% of the patients. The neurological status in 26 patients (13%) deteriorated due to vertebrobasilar ischemia occurring within the 1st postoperative week, and thrombosis or embolism was implicated much more frequently than hemodynamic insufficiency. Subarachnoid hemorrhage (SAH) in 14 patients, vasospasm in five patients, and surgical trauma in seven patients accounted for additional morbidity in the 1st month following operation; however, many of these patients ultimately made an excellent recovery. Late vertebrobasilar ischemic complications or neurological deterioration from persistent mass effect occurred in 4% of patients with successful aneurysm thrombosis 6 weeks to 18 months after arterial ligation. Among the 43 patients with incompletely thrombosed aneurysms, 67% developed early or late neurological deterioration from SAH, progressive brain-stem compression, or brain-stem stroke, with 86% of the complications proving fatal.
