  • [Cerebral deep vascular architectures and subcortical infarcts]. [Journal Article]
    Rinsho Shinkeigaku. 2020 May 19 [Online ahead of print]Yamamoto Y, Nagakane Y, Tomii Y
  • The lenticulostriate arteries (LSA) supply the lateral half of the head of the caudate nucleus, entire putamen, anterior limb, genu and the superior part of the internal capsule (IC) and a part of the corona radiata. The LSA consists with medial, intermediate and lateral branches. The medial branches perfuse the lateral segment of the globus pallidus, the head of the caudate nucleus and the anter…
  • Isolated Infarction of the Splenium: A Rare Presentation of Mild Head Injury. [Case Reports]
    Asian J Neurosurg. 2020 Jan-Mar; 15(1):214-217.Sadashivam S, Natarajan AK
  • Posttraumatic cerebral infarction (PTCI) is a devastating complication of traumatic brain injury. It is usually seen in patients with moderate-to-severe head injury with a reported incidence of 1.9%-10.4%. Brain shift associated with the traumatic intracranial space-occupying lesions with or without severe cerebral edema is the most common mechanism underlying the PTCI. Without associated direct …
  • Preservation of the Lenticulostriate Arteries During Insular Glioma Resection. [Review]
    Asian J Neurosurg. 2020 Jan-Mar; 15(1):16-21.Ghali MGZ
  • Insular gliomas represent 25% and 10% of low- and high-grade gliomas, respectively. Their resection proves challenging due to the intimate involvement of eloquent parenchyma and the lenticulostriate arteries (LSAs), limiting facility of achieving maximal safe resection. The majority of postoperative deficits following insular glioma resection is attributed to compromise of the LSAs. It is contemp…
  • StatPearls: Charcot Bouchard Aneurysm [BOOK]
    . StatPearls Publishing: Treasure Island (FL) Gupta Kashvi K University of Michigan M Das Joe J National Hospital for Neurology and Neurosurgery, Queen Square, London BOOK
  • Charcot-Bouchard aneurysms are minute aneurysms (microaneurysms) in the brain that occur in small penetrating blood vessels with a diameter that is less than 300 micrometers. The most common vessels involved are the lenticulostriate branches (LSA) of the middle cerebral artery (MCA). LSAs originate from the MCA just before its bifurcation, and they can vary between 2 to 12 in number (average 8.1)…
  • Visualization of Lenticulostriate Arteries on CT Angiography Using Ultra-High-Resolution CT Compared with Conventional-Detector CT. [Journal Article]
    AJNR Am J Neuroradiol. 2019 Dec 19 [Online ahead of print]Murayama K, Suzuki S, … Toyama H
  • CONCLUSIONS: Improvements in lenticulostriate artery visualization were the result of the combined package of the ultra-high-resolution CT scanner plus the ultra-high-resolution scanning protocol, which includes higher radiation doses with lower than the national diagnostic reference levels and stronger adaptive iterative dose-reduction processing. This package for ultra-high-resolution CT is a simple, noninvasive, and easily accessible method to evaluate microvasculature such as the lenticulostriate arteries.
  • Lenticulostriate Artery Aneurysm: 2-Dimensional Operative Video. [Journal Article]
    Oper Neurosurg (Hagerstown). 2020 Feb 01; 18(2):E39.Hendricks BK, Spetzler RF
  • Saccular aneurysms that arise from the origin of or along a lenticulostriate artery are rarely observed. In general, occlusion of the lenticulostriate artery is discouraged because of the risk of a capsular infarction. This patient was a woman with moyamoya disease who demonstrated a fusiform aneurysm of a lenticulostriate artery. Image guidance was critical to correctly identify the location of …
  • Unilateral Absence of the Basal Ganglia on 123I-Ioflupane DaTScan. [Case Reports]
    Clin Nucl Med. 2019 Oct; 44(10):842-843.Baghdadi Y, Anh SJ, … Freeman LM
  • This 33-year-old man presented with hemorrhagic stroke manifesting with left hemiparesis and right ptosis. Angiography revealed no patent carotids. The anterior and middle cerebral arteries were filling collaterally through the posterior vertebrobasilar pathway. The presumptive diagnosis was moyamoya disease. The etiology of the bleeding was right basilar tip aneurysm that subsequently had partia…
