Cerebral venous malformations are often misdiagnosed as the cause of symptoms. Further investigation is recommended to identify and treat underlying pathologies independently.

Area of Science:

  • Neurology
  • Neurosurgery
  • Vascular Malformations

Background:

  • Cerebral venous malformations (CVMs) have debated clinical significance despite associations with epilepsy, neurological deficits, and hemorrhage.
  • Distinguishing CVMs as the primary cause of symptoms from coexisting conditions is challenging.

Purpose of the Study:

  • To clarify the natural history of cerebral venous malformations.
  • To propose an appropriate management strategy for patients with CVMs.

Main Methods:

  • Retrospective review of 30 patients with cerebral venous malformations.
  • Pathological confirmation of coexisting cavernous malformations in surgically treated patients.
  • Clinical follow-up ranging from 18 to 104 months.

Main Results:

  • Four patients with cerebellar venous angiomas presented with ataxia.
  • Two patients had confirmed coexisting cavernous malformations.
  • Two patients experienced infarction, and two had tumors.
  • Only five patients remained symptomatic at follow-up; no rebleeding or new neurological events occurred.

Conclusions:

  • Cerebral venous malformations are frequently associated with other symptomatic conditions and may be misattributed as the primary cause.
  • High-field MRI is recommended for "symptomatic" CVMs to detect underlying pathologies.
  • Treatment should target identified underlying pathologies separately from the venous malformation.
