BACKGROUND AND STUDY AIMS:  A great number of unsuccessful intervertebral herniated disk surgeries in the lumbosacral region have highlighted the importance of a comprehensive knowledge of the different types of nerve root anomalies. That knowledge gained by anatomical studies (and intraoperative findings) might contribute to better results. In our study we focused on intraspinal extradural lumbosacral nerve root anomalies and their possible role in radiculopathy. MATERIAL AND METHODS:  The study was performed on 43 cadavers within 24 hours after death (32 men and 11 women)...

BACKGROUND:  Metastasis from one tumor into another is known as tumor-to-tumor metastasis. We report a case of a contiguous occurrence of meningioma and brain cancer metastasis. PATIENT:  A 91-year-old woman presented with a sudden onset of weakness in her right limbs and gait disturbance. Fourteen years previously, she had a tumor that was suspected to be a meningioma in the left frontal convexity with no change for several years. One year earlier to presentation she was diagnosed with lung carcinoma in the left lower lobe...

INTRODUCTION:  A 28-year-old man presented with a history of sensorineural deafness since early childhood treated with bilateral cochlear implants (CIs). He showed signs of debilitating dystonia that had been present since puberty. Dystonic symptoms, especially a protrusion of the tongue and bilateral hand tremor, had not responded to botulinum toxin therapy. We diagnosed Mohr-Tranebjaerg syndrome (MTS). METHODS AND MATERIAL:  Deep brain stimulation (DBS) of the bilateral globus pallidus internus was performed predominantly with stereotaxic computed tomography angiography guidance under general anesthesia...

BACKGROUND AND STUDY AIMS:  Vascular narrowing or obstruction reduces blood flow to the lower limbs during exercise or at rest. Symptoms may range from intermittent claudication to pain at rest. Narrowing of these arteries may produce pain in the buttocks, thighs, or legs. These symptoms may resemble those of lumbar radicular pain. Spine surgeons may overlook obstructive vascular lesions of the lower limbs in patients with lumbar degenerative diseases such as spinal stenosis and spondylolisthesis...

BACKGROUND AND STUDY AIMS:  Computed tomography (CT) and magnetic resonance image (MRI) data have been widely used to for navigation in various neurosurgical operations. However, delicate intracranial structures cannot be displayed using only one imaging method. Navigation with multimodality imaging was developed to better visualize these structures in glioma removal, but whether it is useful in endoscopic transsphenoidal surgery is unknown. We describe our clinical experience using multimodality imaging for navigation in endoscopic transsphenoidal surgeries...

BACKGROUND AND STUDY AIMS:  Spinopelvic sagittal balance is important in managing lumbar diseases. We evaluated the change in spinal sagittal alignment after microendoscopic laminotomy in patients with low-grade degenerative spondylolisthesis (DS). MATERIAL AND METHODS:  We retrospectively reviewed the records of 87 patients who underwent microendoscopic laminotomy. We enrolled 35 patients with DS and 52 patients without DS. Spinopelvic parameters were evaluated, including the sagittal vertical axis (SVA), lumbar lordosis (LL), sacral slope, pelvic tilt, and pelvic incidence (PI)...

BACKGROUND AND IMPORTANCE:  Pituitary apoplexy (PA) occasionally occurs in patients with pituitary adenoma and may cause severe functional deficits. Headache, pituitary insufficiency, visual impairment, and cranial nerve palsies are the most frequent symptoms in patients with PA. Secondary cerebral ischemia develops in only a limited number of PA patients. Two pathogenic mechanisms were previously proposed. One states that ischemia may be due to major vessel encasement or to vessel compression, as a result of extended tumor growth...

OBJECTIVE:  Over the past few years bipolar electrocoagulation techniques in neurosurgery have been continually improving. However, limited access during endoscopic endonasal transsphenoidal surgery (EETS) for central skull base pathologies and the requirement of very precise coagulation in that dedicated anatomical area requires further refinement of bipolar coagulation instruments. We describe our experience (effectiveness of coagulation, intraoperative handling, and the use as a dissecting tool) with a new type of coagulation forceps, the Calvian endo-pen (Sutter Medizintechnik, Freiburg, Germany) during EETS...

Rongjun Qian, Zhixiao Li, Ming Li
Vertebral arteriovenous fistula (AVF), a complication of a vertebral artery injury (VAI), is a rare but serious complication of upper cervical spine fixation surgery. We report a case of a 59-year-old female patient who had a vertebral AVF following transpedicular occipitocervical fixation surgery. Endovascular embolization of the AVF was successfully performed using ethylene vinyl alcohol. From this case we learned that preoperative evaluation of the course of the vertebral artery is necessary, and vertebral artery embolism is an effective and safe method to treat vertebral AVF after proof of a patent second vertebral artery...

BACKGROUND:  Arteriovenous malformations (AVMs) of the scalp are rare and infrequently encountered by the neurosurgeon. CASE DESCRIPTION:  We report a unique case of a 42-year-old patient who presented with a progressive worsening of visual acuity in the right eye (lower quadrantanopia) and palpebral ptosis. Physical examination revealed a right exophthalmos and a right frontoparietal scalp soft swelling when the patient was in the supine position. Neurologic work-up showed a scalp AVM extending into the orbit and connected to an intraorbital cavernous angioma...

BACKGROUND:  Anterior cervical fusion (ACF) with autologous bone was reported > 50 years ago. The continuous development of materials with elastic properties close to that of the cortical bone improves induction of osteogenesis and simplifies the technique of interbody fusion. To determine the safety and efficiency of stand-alone trabecular metal (TM) (or porous tantalum) cages for ACF, we performed a retrospective analysis of 88 consecutive patients with one-level or two-level degenerative disk disease (DDD) causing cervical myelopathy treated by interbody fusion with stand-alone TM cages...

BACKGROUND AND STUDY AIM:  Colloid cysts usually occur in the anterior third ventricle at the level of the foramina of Monro. Colloid cysts may extend from the third toward the lateral ventricle. We present a rare case of multiple intraventricular colloid cysts, two of which were in the third ventricle and one in the lateral ventricle. CLINICAL DESCRIPTION:  A 40-year-old female patient presented with three intraventricular cystic lesions: one cyst in the typical localization in the anterior rostral third ventricle, another cyst behind it in the same (third) ventricle, and a larger bulging cyst in the right lateral ventricle...

BACKGROUND:  Cortical bone trajectory (CBT) is a relatively new technique for pedicle screw insertion in the field of spine surgery. Previous studies have demonstrated the significantly better pullout and toggle characteristics the new method offers, and it appears to have certain advantages over the widely used traditional trajectory. The mechanism of the pullout and toggle characteristics still remains unknown. PURPOSE:  To report the medium- to long-term follow-up findings of patients who underwent posterior lumbar interbody fusion or posterior lumbar fusion (PLIF/PLF) at our institution and to discuss the ideal screw trajectory when using this technique...

BACKGROUND:  Percutaneous endoscopic lumbar diskectomy is a good treatment modality for lumbar disk herniation. However, when a patient complains of bilateral lower limb radicular pain with severe disk protrusion at the L5-S1 level, the transforaminal approach is often unable to resolve both lesions owing to anatomical limitations. It is also very difficult to resolve both lesions in an ipsilateral direction using the percutaneous interlaminar approach. We report our surgical technique and clinical results using a ventral dural approach of percutaneous endoscopic interlaminar lumbar diskectomy for L5-S1 herniated nucleus pulposus (HNP) in patients with bilateral radiculopathy due to a severe disk protrusion...
