The incidence of radiation-induced moyamoya among pediatric brain tumor patients who received photon radiation versus those who received proton beam therapy: a systematic review
AbstractCranial irradiation is associated with several adverse events such as endocrinopathy, growth retardation, neurocognitive impairment, secondary malignancies, cerebral vasculopathy, and potential stroke. The better side effects profile of proton beam therapy compared with that of photon radiation therapy is due to its physical properties, mainly the sharp dose fall-off after energy deposition in the Bragg peak. Despite the better toxicity profile of proton beam therapy, the risk of   moyamoya syndrome still exists. We conducted a systematic review of the existing literature on moyamoya syndrome after receiving crani...

Combined Endovascular Antegrade and Direct Retrograde Carotid Artery Stenting for Chronic and Long Segment Common Carotid Artery Occlusion: Technical Note and Review of Literature
Neurol Med Chir (Tokyo). 2023 Apr 6. doi: 10.2176/jns-nmc.2022-0397. Online ahead of print.ABSTRACTCommon carotid artery (CCA) occlusion (CCAO) is a rare cause of ischemic stroke and bypass surgery is the common treatment approach. However, safer alternatives should be developed to treat CCAO. A 68-year-old male was diagnosed with left-sided CCAO with decreased left visual acuity due to neck radiation therapy for laryngeal cancer. Recanalization therapy using a pull-through technique was initiated because cerebral blood flow progressively decreased during the follow-up period. First, after a short sheath was inserted into ...

115 SMART: A rare syndrome with potentially devastating consequences
We report three cases with differing neurological presentations and outcomes. A 57 year old female with previous cranial radiotherapy for a frontal astrocytoma treated 9 years earlier presented with a two week history of headache, aphasia and right sided hemiparesis. MRI Brain demon- strated new extensive left hemispheric enhancement with extensive effacement of the ipsilateral cerebral sulci. 40 days following her presentation she started to improve and is now in rehabilitation. A 33 year old female with a background of medulloblastoma treated with cranio-spinal radiotherapy 19 years earlier presented with worsening confu...

SMART Syndrome (Stroke-like migraine attacks after radiation therapy): When to suspect it?
CONCLUSION: The triad of migraine, seizure, and hemiparesis within the context of a prior brain radiotherapy should promptly raise the suspicion of SMART syndrome. Prompt diagnosis is essential to avoid unnecessary invasive investigations.PMID:34877047 | PMC:PMC8645481 | DOI:10.25259/SNI_893_2021
