Intracranial cavernous angiomas frequently cause cerebral hemorrhage, leading to significant neurological deficits and mortality. Surgical intervention is recommended for symptomatic lesions, while asymptomatic cases require careful monitoring.

Area of Science:

  • Neurology
  • Neurosurgery
  • Radiology

Background:

  • Intracranial cavernous angiomas are vascular malformations with a significant risk of hemorrhage.
  • Understanding their clinical presentation and radiological features is crucial for effective management.

Purpose of the Study:

  • To analyze clinical features, bleeding risk, radiological findings, and treatment strategies for intracranial cavernous angiomas.
  • To evaluate outcomes in patients with symptomatic and asymptomatic lesions.

Main Methods:

  • Retrospective analysis of 14 cases of intracranial cavernous angioma.
  • Review of 153 previously published cases, totaling 167 cases.
  • Categorization of lesions based on symptomatology and surgical risk.

Main Results:

  • Cerebral hemorrhage occurred in 44% of cases, with a 12.2% mortality rate in typical hemorrhagic patterns.
  • Neurological deficits were observed in 42.5% of patients post-hemorrhage, and 16.4% experienced rebleeding.
  • Treatment strategies varied based on lesion classification (symptomatic/asymptomatic, low/high surgical risk).

Conclusions:

  • Intracranial cavernous angiomas pose a substantial risk of hemorrhage and associated morbidity.
  • Surgical treatment is indicated for symptomatic lesions, particularly in low-risk areas.
  • Asymptomatic, high-risk lesions warrant initial conservative management with serial imaging, with surgery considered if symptoms or radiological changes occur.
