Acrodysostosis is a rare syndrome characterized by peripheral dysostosis, nasal hypoplasia, and frequently mental retardation. Only two adult cases of acrodysostosis have been reported to have neurological symptoms. ⋯ Special attention should be given to these patients to detect signs of spinal stenosis, as early decompression can lead to neurological recovery.

Review
The circular sinus: an anatomic study with neurosurgical and neurointerventional applications.
Skull base surgery requires knowledge of the intracranial venous sinuses, which overall have been well studied. However, the intercavernous sinuses and their contribution to the so-called circular sinus have received scant attention. ⋯ A true "circular sinus" (type II) is present in only a few cases; both intercavernous sinuses disconnected are found in most specimens. No intercavernous sinus was found within the free edge of the diaphragma sella, which is typically depicted. These data are useful for invasive and minimally invasive procedures of the parasellar region.

Review Case Reports
Occlusion of all aortic arch great vessels: acute revascularization to perform endovascular stroke therapy.
We present a case of a patient with a left-sided stroke and occlusion of all aortic arch great vessels who was treated successfully with endovascular intervention followed by delayed cardiothoracic revascularization. ⋯ We report a rare case of occlusion of all aortic arch great vessels. Combined endovascular intervention and surgical revascularization resulted in an excellent durable outcome.

The occipital artery (OA) is an important donor artery for posterior fossa revascularization. Harvesting the OA is believed to be difficult and time consuming due to its 3-dimensional course through different suboccipital tissue layers. We propose a safe and effective means of dissecting the OA. ⋯ This segmentation provided a safe and effective procedure for harvesting the OA, in which dissection of the transitional segment is a critical step. Although the course of the OA is complex, precise anatomical knowledge of the suboccipital muscles and a stepwise dissection make harvesting the OA relatively simple.

Review Historical Article
Focused ultrasound: relevant history and prospects for the addition of mechanical energy to the neurosurgical armamentarium.
Although the concept of focused ultrasonography emerged more than 70 years ago, the need for a craniectomy obviated its development as a noninvasive technology. Since then advances in phased array transducers and magnetic resonance imaging technology have resurrected the ultrasound as a noninvasive therapeutic for a plethora of neurological conditions ranging from embolic stroke and intracranial hemorrhage to movement disorders and brain neoplasia. ⋯ In addition, focused ultrasound comes without the general complexity or the risks of ionizing radiation that accompany radiosurgery. As the quest for minimally invasive and noninvasive therapeutics continues to define the new neurosurgery, the focused ultrasound evolves to join the neurosurgical armamentarium.
