The occurrence of benign peripheral nerve sheath tumors (PNSTs) is not uncommon. The surgical excision of symptomatic benign PNSTs along with preservation of the affected nerve and its function is an ideal treatment option. ⋯ Benign PNSTs have excellent clinical outcome, and the goal for surgical treatment is total to gross total excision of the tumor with neural preservation.

Imaging is paramount to the diagnosis and management of ischemic stroke, offering a battery of structural and functional probes of cerebrovascular physiology. The technical underpinnings of stroke imaging continue to evolve, bringing the neuroscience community increasingly closer to high-resolution, tissue-level biomarkers of brain perfusion, metabolism, and viability. The rapid expansion of neuroimaging in this domain has met with controversies, and in many respects, a lack of generalizable conclusions regarding optimized use in cerebrovascular disease. This review aims to provide the reader with the depth and scope of both established and emerging techniques, and an overview of prevailing viewpoints regarding neuroimaging in acute ischemic stroke.
