Communicating branches between the tibial and common fibular divisions of the sciatic nerve have not been previously described. The aim of our study was to examine such neural connections. ⋯ To our knowledge, neural interconnections between the divisions of the sciatic nerve in the posterior thigh have not been described in the extant literature. Such data might help explain unusual neurologic examinations and alert the surgeon as to the potential for encountering such connections at operation.

Randomized allocation of treatment options is not well accepted within the clinical community. Some methods of implementation may be received more favorably than others. Prerandomization may be an acceptable means to facilitate recruitment in some clinical trials. ⋯ Until the ethical functions of randomized allocation of selected treatment options in the care of patients are recognized by the neurovascular community, Zelen's prerandomization may help recruitment into difficult trials and contribute a means to provide best possible care in the presence of uncertainty.

The primary auditory cortex, which was previously considered to be unisensory, has been shown to be multisensory. However, the temporal details of processing nonauditory stimuli in the human auditory cortex remain unclear, owing to the low temporal and spatial resolution of the adopted imaging techniques. ⋯ These findings provide novel evidence for multisensory interplay within human auditory cortex at an early stage of cortical processing, which extends the understanding of multisensory mechanisms of human brain functions.

Among the rare intraventricular cavernomas, purely intra-aqueductal cavernomas are exceptionally rare. ⋯ We discuss the rationale that led us to treat hydrocephalus with neuroendoscopy, which offered the possibility to directly inspect the intra-aqueductal lesion, make the diagnosis of cavernoma, and treat symptoms resulting from hydrocephalus without increasing the risk of bleeding.

Pseudoaneurysms of scalp arteries have been reported in rare cases after iatrogenic injury; however, they are far more commonly seen after traumatic injuries. They are usually associated with the superficial temporal artery; however, there have been a few reports of psuedoaneurysms of the occipital artery (OA). ⋯ The patient recovered fully after endovascular embolization. Other treatment options for pseudoaneurysms of facial, temporal, and scalp arteries include surgical clipping/trapping with excision, Hunterian ligation, or direct compression. Pseudoaneurysms of extracranial scalp arteries are rare and most often caused by traumatic compression of the artery against a bony ridge. Despite their rarity, pseudoaneurysms secondary to iatrogenic injury to extracranial arteries should be considered in the differential diagnosis in patients presenting with delayed incisional pain, redness, and swelling.
