Varicella zoster virus remains dormant in the dorsal root ganglia after childhood exposure to chickenpox. Its reactivation results in herpes zoster, otherwise known as shingles, which is a painful vesicular rash in a dermatomal distribution. We present a case of foraminal disk extrusion that resulted in radicular pain in a dermatomal distribution. The resultant inflammatory response around the dorsal root ganglion triggered an episode of shingles, which elegantly highlights the pathophysiology of this condition at a gross anatomic level.

Venous outflow obstructions are rare anatomic findings that can appear with symptoms of elevated intracranial pressure, including headache and vision loss, and can be mistaken for more common diagnoses, such as idiopathic intracranial hypertension (IIH) or cerebral venous sinus thrombosis (CVST). Although venous outflow obstructions have been reported in rare bone dysplasias and congenital abnormalities, to date they have not been reported in renal osteodystrophy (ROD), a relatively common disorder seen in patients with chronic kidney disease. ⋯ This report reviews the presentation, pathology, and neurosurgical treatment of patients with ROD and venous outflow obstructions, and explores the differential diagnoses of outflow obstructions, IIH, and CVST. To our knowledge, this is the first report of intracranial hypertension from jugular foramen stenosis secondary to renal osteodystrophy.

To investigate effect of July admission on short-term outcome after endovascular coiling of patients with subarachnoid hemorrhage (SAH) owing to ruptured aneurysms. ⋯ Based on findings of this national investigation, patients with SAH owing to ruptured aneurysms who undergo endovascular therapy during the beginning of the academic year in July may not have worse short-term outcome compared with patients with admissions during other months.

Stereotactic radiosurgery (SRS) is generally considered a minimally invasive treatment modality. However, definitive evidence of the efficacy of SRS in the elderly population is still not available. ⋯ Therapeutic effects and outcomes of SRS are similar in elderly and nonelderly patients. Treatment-related neurologic deficits are rare, and longer EFS can be expected.

A case of asymptomatic occipital condyle fracture with incomplete occipito-cervical dislocation: how did it happen?
Atlanto-occipital dislocation (AOD) is a lesion rarely observed in a trauma center, because of high mortality in the preclinical phase. The number of AOD survivors is increasing thanks to the improvement in prehospital resuscitation. ⋯ We recommend a rapid immobilization with spine table and cervical collar, the consensual stabilization of hemodynamic and respiratory parameters, and a successive prompt occipitocervical stabilization. C2 should be included in the stabilization because of the ligamentous conformation of craniocervical joint.
