Intracerebral cavernous angiomas, vascular malformations in the brain, can cause seizures and hemorrhage. Surgical treatment provides an excellent prognosis for seizure control in affected patients.

Area of Science:

  • Neurology
  • Neurosurgery
  • Neuroradiology

Background:

  • Intracerebral cavernous angiomas are vascular malformations that can lead to significant neurological symptoms.
  • Understanding their presentation and diagnostic characteristics is crucial for effective management.

Purpose of the Study:

  • To evaluate the clinical presentation, diagnostic imaging findings, and treatment outcomes of intracerebral cavernous angiomas.
  • To assess the efficacy of surgical intervention for seizure control.

Main Methods:

  • Retrospective study of 31 patients with histologically confirmed intracerebral cavernous angiomas.
  • Analysis of clinical symptoms, neuroimaging (CT, MRI, angiography), and surgical outcomes.

Main Results:

  • Twenty-two patients were symptomatic, primarily with seizures (100%), intracranial hemorrhage (13.6%), or space-occupying lesion signs (4.5%).
  • Lesions were predominantly in the neocortex (27/31). CT identified lesions in 16/27 cases, with contrast enhancement in 6/7 and calcification in 10/27.
  • MRI showed characteristic T2-weighted signal abnormalities and was diagnostic in 5 cases. Angiography was normal in 8/17 cases.

Conclusions:

  • Intracerebral cavernous angiomas present with diverse neurological symptoms, most commonly seizures.
  • Surgical treatment is highly effective in achieving seizure control for patients with these lesions.
