Cerebral cavernous hemangiomas, also known as cavernous malformations or cavernomas, are complex vascular abnormalities that can occur within the brain. These abnormal blood vessels are characterized by dilated, thin-walled caverns or sacs that can accumulate blood over time.
Cerebral cavernous hemangiomas are typically congenital, meaning they are present at birth, although they may not become symptomatic until later in life. They can be either sporadic, occurring in isolation, or part of a familial condition known as familial cerebral cavernous malformations.
Symptoms of cerebral cavernous hemangiomas can vary widely depending on the location and size of the malformation, as well as the individual. Common symptoms include seizures, neurological deficits, such as weakness or numbness, headaches, and cognitive impairments. However, some individuals may remain asymptomatic throughout their lives.
Diagnosis of cerebral cavernous hemangiomas often involves magnetic resonance imaging (MRI), which can accurately visualize the blood-filled lesions in the brain. Treatment options for cerebral cavernous hemangiomas primarily focus on managing symptoms or preventing complications. Neurosurgical intervention may be required in cases where the malformation is causing significant neurological deficits or recurrent bleeding.
In summary, cerebral cavernous hemangiomas are vascular abnormalities within the brain characterized by dilated, thin-walled caverns or sacs filled with blood. They may be congenital and can cause a range of symptoms, including seizures, neurological deficits, headaches, and cognitive impairments. Diagnosis is typically done through MRI imaging, and treatment options vary based on the individual's symptoms and risks associated with the malformations.
