Sporadic Meningioangiomatosis: Bystander or Curious Culprit.

In this report, we describe two cases of sporadic meningioangiomatosis (MA) - a rare condition of the central nervous system known to cause headaches, seizures and other focal neurologic deficits. Both patients presented with headache and vision change, somewhat suggestive of migraine. The combination of magnetic resonance imaging (MRI) and computerized tomography (CT) can establish the diagnosis of MA.

Treatment of colloid cyst of the third ventricle by stereotactic aspiration followed by radiosurgery: Report of four cases.

BACKGROUND: Colloid cysts are rare benign lesions with potentially devastating results. Complications intra and posttreatment can result in high rates of recurrence. Stereotactic radiosurgery may present an attractive option for decreasing the rate of recurrence in conjunction with stereotactic aspiration. CASE DESCRIPTION: Here, we report four cases of colloid cyst of the third ventricle managed by stereotactic aspiration with the use of the Leksell frame followed by stereotactic radiosurgery with the BrainLab/Novalis linear accelerator. Follow-up ranged from 7 to 10 years. There were no complications related to the treatment and no recurrence of the cysts, to date. All four patients remain asymptomatic. CONCLUSIONS: The combination of stereotactic aspiration and radiosurgery may have a role in the management of colloid cysts of the third ventricle.

The Asfora Bullet Cage System Shows Comparable Fusion Rate Success Versus Control Cage in Posterior Lumbar Interbody Fusion in a Randomized Clinical Trial.

BACKGROUND: Low back pain and degeneration of the intervertebral disc are an integrated malady that affects millions of Americans. Cage devices used in association with posterior lumbar interbody fusion (PLIF) have been shown to be an effective approach in the treatment of a number of lower spine disorders attributed to degenerative disc disease (DDD). OBJECTIVE: This study was undertaken as part of a U.S. Food and Drug Administration (FDA) Investigational Device Exemption (IDE) study and compares the effectiveness of the Asfora Bullet Cage System (ABCS) to successfully fuse vertebra at one or two levels between L2 and S1 in patients with DDD to an FDA approved comparison device, the Medtronic-Sofamor Danek Inter Fix Threaded Fusion Device (MSDIFD). METHODS: A total of 257 randomized participants were implanted with either the ABCS device (n = 132) or the MSDIFD device (n = 125) through an open posterior approach using autogenous local bone graft without the use of pedicle screws. Patients were evaluated prior to surgery and at the 24 month (24-M) visit for fusion status, deep tendon reflex status, sensory function, motor function, straight leg raise status, pain, disability, and device safety. Radiological evaluation and statistical analysis were performed by independent professionals. RESULTS: Evaluation of device success was performed at 24-M visit. From the original group of 257 patients, 59 were lost to follow-up. Primary measures of success at the 24-M visit involved pain and function, fusion, neurological status, and device-related adverse events measures. Pain and function improved in both (MSDIFD: 75.7 percent; ABCS: 82.6 percent). Fusion success with all radiographic points at 24-M visits was 79.4 percent MSDIFD and 88.2 percent ABCS. Neurological improvement was seen in both (MSDIFD: 77.0 percent; ABCS: 87.8 percent). One device-related grade 1 adverse event was reported in the MSDIFD group. Disc height preservation was equivalent for single level fusions (MSDIFD: 16.1 percent; ABCS: 20.0 percent) and second level fusions (MSDIFD: 10.7 percent; ABCS: 14.3 percent). General health and well-being improvement was the same (MSDIFD: 37.0 percent; ABCS: 40.0 percent). Subsequent fusion, up to 10 years, was equivalent (MSDIFD: 83.8 percent; ABCS: 91.2). Results for both devices were considered to be satisfactory, with a slight non-significant superiority for the ABCS. CONCLUSION: From the ABCS device FDA IDE sanctioned study and the review of the literature, we concluded that the Asfora Bullet Cage System is safe, effective and comparable to other interbody fusion devices which are used stand-alone or in conjunction with pedicle screws, rhBMP-2, or autogenous bone harvested from the iliac crest inserted through anterior, lateral or posterior approaches.

8-year-old patient with multiple large cerebral abscesses successfully treated with stereotactic aspiration: case report and literature review.

The case presented herein is of an 8-year-old female with nine large brain abscesses of unknown etiology. One lesion was excised by craniotomy. Two days later, in view of impending brain herniation, the remaining eight abscesses were treated on an urgent basis by stereotactic aspiration. Immediate postoperative CT showed total disappearance of all lesions. This case demonstrates that some brain abscesses can be successfully treated utilizing a minimally invasive technique and aggressive antibiotic therapy, without necessitating surgical removal of abscess capsule, multiple aspirations, or implantation of an irrigation system.

Case report: treatment of subdural hematoma in the emergency department utilizing the subdural evacuating port system.

Patients with acute or chronic subdural hematomas may present with rapidly deteriorating neurological function and are at risk for irreversible brainstem injury. In such cases, rapid surgical intervention is required to evacuate the hematoma and reverse critically elevated intracranial pressure. A variety of surgical drainage methods are in existence, none of which are clearly superior to the others. This report presents the case of a 74-year-old woman who suffered an acute-on-chronic subdural hematoma which was evacuated in the emergency department utilizing the subdural evacuating port system (SEPS). The SEPS provides for a minimally invasive technique to drain subdural hematomas and is advantageous in that it can be performed at the bedside. The SEPS is relatively simple to use and may be especially useful to emergency department staff in outlying areas where there is a shortage of neurosurgical coverage.

Extreme multi-level anterior cervical discectomy and fusion.

The use of anterior cervical discectomy and fusion (ACDF) is a common procedure used to treat those who suffer from degenerative disc disease (DDD) of the cervical spine which may result in spondylolisthesis, spinal stenosis, disc herniation, nerve root and/or cord compression. ACDF is regularly used for the fusion of one to four cervical spine levels; however, the literature documenting the fusion of 5 or 6 levels is surprisingly lacking. In this retrospective review of our case series, we document two 5-level and two 6-level ACDF in elderly patients using custom made titanium fusion plates and patellar allograft bone for interbody placement without posterior fixation. The documentation of these long anterior constructs without supplemental posterior fixation or the use of a halo vest apparatus, but a simple neck collar for three months, is an important contribution to the literature illustrating that with utilization of appropriate technique, a high number of levels can be safely fused in the elderly patients necessitating this particular procedure.

Successful fusion of remote type II odontoid fracture using anterior screw fixation of the odontoid and rhBMP-2: report of two cases.

Anterior screw fixation of the odontoid is contraindicated in remote type II fractures. The alternative surgical treatment consists of a posterior C1 to C2 or an occiput to C3 fusion, which is met with much resistance by patients as this option limits head motion, especially rotational movement. Furthermore, elderly patients may not be medically fit to undergo surgery of this magnitude. This report presents two remote type II odontoid fractures in elderly patients (67 and 73 years of age) who were successfully treated by means of anterior screw fixation of the odontoid along with an injection of recombinant human bone morphogenic protein (rhBMP-2) (Medtronic Inc.) into the fracture line with infiltration of the fibrous union tissue and adjacent anterior longitudinal ligament. To our knowledge, this is the first documented report of solid fusion of remote type II odontoid fracture treated with rhBMP-2 and anterior screw fixation. The authors believe that this technique may be a viable alternative for the treatment of failed odontoid fractures older than six months.

A modified technique to treat chronic and subacute subdural hematoma: technical note.

BACKGROUND: We present a patient on warfarin in whom a drainage port system was attached to the skull, successfully draining a subacute subdural hematoma. CASE DESCRIPTION: An elderly male presented to our institution with right hemiparesis a week following a motor vehicle accident. He was on warfarin for recurrent pulmonary emboli and suffered from severe coronary artery disease. Physical examination demonstrated a grade 3/5 hemiparesis and a computerized tomography (CT) scan confirmed the diagnosis of subacute subdural hematoma. He underwent twist drill craniostomy and attachment of the subdural evacuating port system. Recovery in this patient was dramatic. CONCLUSION: The subdural evacuating port system (SEPS) permits the neurosurgeon to drain subacute or chronic hematomas by a method that is minimally invasive, simple, and safe. The SEPS appears to promote brain expansion without the potential biohazards of other standard techniques.
