نظرة عامة

التشوهات الوريدية داخل الجمجمة هي أوردة داخل الدماغ تكون كبيرة بشكل غير عادي. ومن غير المحتمل أن تسبب هذه الأوردة الكبيرة أعراضًا أو تؤثر في طريقة عمل الأوردة.

قد يصاب بعض الأشخاص بتشوه وريدي داخل الجمجمة لا يُشخَّص مطلقًا ولا يسبب أعراضًا أبدًا. وفي بعض الأحيان، يمكن اكتشافها بطريق الصدفة عندما تُجري اختبار تصوير دماغ مطلوبًا لتشخيص مرض آخر.

لا تتطلب التشوهات الوريدية داخل الجمجمة عادة العلاج.

الأعراض

Intracranial venous malformations may never cause symptoms. They are sometimes found by accident during brain imaging tests for another condition. If an intracranial venous malformation does cause symptoms, they may include:

  • Headaches.
  • Seizures.
  • Dizziness.
  • Nausea and vomiting.
  • Muscle weakness or paralysis.
  • Loss of coordination.
  • Vision troubles.
  • Difficulty speaking.
  • Memory problems.

When to see a doctor

Seek medical attention if you have any of the symptoms of an intracranial venous malformation.

الأسباب

Experts don't understand what causes intracranial venous malformations. Certain genetic changes might play a role, and the malformations may happen during fetal development. However, some types may not be inherited and are acquired later in life, possibly after an injury to the central nervous system.

عوامل الخطورة

Having a family history of intracranial venous malformations can increase your risk. But most types aren't inherited.

Certain hereditary conditions can increase your risk of intracranial venous malformations. These include hereditary hemorrhagic telangiectasia, Sturge-Weber syndrome and Klippel-Trenaunay syndrome.
