A 30-year-old male presented with sudden loss of consciousness and subarachnoid hemorrhage and was transferred to our hospital. On admission, his level of consciousness was assessed as Japan Coma Scale 100 and Glasgow Coma Scale 8 (E1V2M5), with severe paralysis of the right upper and lower limbs. Computed tomography and magnetic resonance imaging demonstrated a partially thrombosed middle cerebral artery aneurysm with a maximum diameter of 31 mm at the M2 non-branching segment of the left middle cerebral artery mid-trunk. Cerebral angiography indicated potential collateral circulation, no retrograde opacification of the aneurysm, and absence of perforating branches near the lesion, so we selected endovascular parent artery occlusion that targeted only the proximal portion of the aneurysm. Postoperative care focused on managing intracranial pressure and overall systemic management. The patient recovered without significant infarction and was discharged home with a modified Rankin Scale score of 1 4 months after the onset. In general, peripheral aneurysms are less likely to cause perforator infarcts, and larger aneurysms are more tolerant of parent artery occlusion.

Although comprehensive genetic analysis has recently uncovered the molecular characteristics of radiation-induced glioma, the full picture remains unclear due to its rarity. A 45-year-old man presented with generalized seizures caused by multiple brain tumors involving the right frontal lobe, thalamus, and brainstem. The patient had a history of whole-brain radiotherapy for recurrent Burkitt's lymphoma at the age of 12. He underwent craniotomy, and the histological diagnosis revealed a high-grade glioma with isocitrate dehydrogenase-wildtype, which was presumed to be a radiation-induced glioma that developed 33 years after whole-brain irradiation. Next-generation sequencing identified a <i>CDKN2A/B</i> deletion, as well as coamplification of several receptor tyrosine kinases-encoding genes, including <i>PDGFRA</i>, <i>KIT</i>, and <i>KDR</i>, all of which are located at 4q12. Amplification of this region is broadly observed across cancers and is associated with poor prognosis in sporadic glioblastoma. Nevertheless, the patient received chemoradiotherapy with temozolomide, followed by temozolomide maintenance therapy, resulting in a complete response of all lesions. Although radiation-induced gliomas are generally difficult to treat, our patient unexpectedly responded well to conventional chemoradiotherapy despite the coamplification of multiple receptor tyrosine kinases-encoding genes, which is typically suggestive of an aggressive phenotype.
