Case in brief
A long-term glioblastoma survivor developed multiple late complications after cranial radiation therapy, including a radiation-induced intracranial aneurysm. Serial imaging showed proximal large-artery stenosis or occlusion and hemodynamic stress associated with aneurysm formation. The report emphasizes that vascular risk in this setting may not be explained by radiation dose distribution alone. The abstract does not specify the aneurysm’s treatment or clinical resolution.
What made this case unusual
Serial imaging linked proximal arterial stenosis or occlusion and resulting hemodynamic stress with aneurysm formation, highlighting a potential contributor beyond radiation exposure itself.
Diagnostic / clinical pearl
In a long-term survivor after cranial irradiation, assess cerebrovascular risk in light of both radiation dose distribution and evolving hemodynamic changes, including arterial stenosis or occlusion.
Why it matters
Late radiation-related complications can accumulate in one survivor and affect outcome; longitudinal vascular assessment may help identify preventable morbidity.
