    Cerebral angiography reveals intracranial aneurysms can enlarge, correlating with patient deterioration. Irregular or multilocular aneurysm shapes were consistently observed in these cases.

    Area of Science:

    • Neurology
    • Radiology
    • Vascular Imaging

    Background:

    • Cerebral angiography is the gold standard for in vivo demonstration and study of intracranial aneurysms.
    • Understanding aneurysm morphology and behavior is crucial for managing patients with these vascular malformations.

    Observation:

    • In 16 cases, clinical deterioration was observed to parallel a variable degree of aneurysm enlargement.
    • All aneurysms studied exhibited irregular or bilocular/multilocular morphology.

    Findings:

    • Aneurysmal enlargement in the intracranial vasculature is a significant finding.
    • Irregular and multilocular aneurysm shapes are consistently associated with enlargement and clinical decline.

    Implications:

    Related Experiment Videos

  • The findings suggest that changes in aneurysm size and morphology are critical indicators of potential clinical deterioration.
  • Further research into the factors causing aneurysmal enlargement may lead to improved diagnostic and therapeutic strategies for intracranial aneurysms.
