Our study aims to contribute to existing knowledge by evaluating patients with low back pain to provide a more accurate relationship between the diameter of the intervertebral foramen and the clinical, demographic, and lumbar spine anatomic factors such as age, sex, body mass index, the Zurich Claudication Questionnaire, facet joint, intervertebral disc, ligamentum flavum, and spinal canal. ⋯ The results of the present study allow us to quantify the effect of age, DSCSA, and lumbar disc degeneration grade on the FA.

Pure Intrasellar Meningioma Mimicking Pituitary Adenoma: A Novel Neuroradiologic Finding.
Pure intrasellar meningioma is an extremely rare tumor that is difficult to diagnose as it resembles a pituitary adenoma in its clinical, endocrinologic, and radiologic presentation; it can only be distinguished through histopathologic examination. All previously reported cases of this lesion were considered those of pituitary adenoma at the initial diagnosis. ⋯ We report a case of a pure intrasellar meningioma in a 27-year-old man. A boundary between the tumor and pituitary gland may be evident on magnetic resonance imaging, thus enhancing the diagnosis of pure intrasellar meningioma.

To comprehensively analyze malpractice claims relating to arteriovenous malformations. ⋯ While the courts rule in favor of defendants more than plaintiffs, the time and psychological demands of litigation place a high burden on physicians.

Trigeminal neuralgia may be treated via percutaneous access to the foramen ovale (FO). Vascular complications associated with the needle trajectory can result in serious morbidity and mortality. This study aimed to correlate the vascular relationships of the FO at the skull base via cadaveric dissections and computed tomography (CT). ⋯ Cadaveric delineation of vascular structures in the infratemporal fossa correlates with head CT imaging and may be used to accurately plan percutaneous access to the FO. Inadvertent puncture of the extracranial internal carotid artery is nearly impossible with good technique. The most likely source of percutaneous vascular injury is the middle meningeal artery and distal branches of the maxillary artery.

Although neurotropic, the varicella-zoster virus (VZV) is a rare cause of mycotic cerebral aneurysms. As with other mycotic aneurysms, medical management can provide complete resolution. Surgery for refractory aneurysms can be complicated by vessel friability and complex morphologies requiring excision and revascularization. ⋯ Postoperatively, she was at her neurologic baseline and was discharged 2 weeks later. Immediate and 5-month postoperative vascular imaging demonstrated bypass patency and no residual aneurysm. Similar to other mycotic aneurysms, VZV-associated cerebral aneurysms refractory to medical management can be safely treated with definitive excision and revascularization in selected patients.
