Cerebral cavernous hemangioma 1.4mm needs to be treated with surgery if there is a high risk of rupture or if there are symptoms, but on the contrary, it can be treated conservatively in order to avoid any impact on your health. Cerebral cavernous hemangioma, usually refers to spongy abnormal blood vessel clusters composed of numerous weak blood vessels, usually occurs in the skull, but may also appear in extracranial areas, such as the liver or the orbit. The exact etiology of formation is unknown, but it is characterized by familial inheritance. Cerebral cavernous hemangiomas can be asymptomatic if they do not rupture and bleed, but there is a tendency for them to spontaneously rupture and bleed. When a cavernous hemangioma is detected in a patient with a high risk of rupture or symptoms such as headaches or seizures, surgical resection is the primary treatment, regardless of size, with the main goal of eliminating the risk of bleeding from the lesion, reducing or preventing seizures, and restoring neurological function. If the risk of rupture is assessed by the doctor to be low, and the patient has no obvious symptoms or physical difficulty in tolerating surgery, the patient may be treated conservatively at first, with close monitoring of the condition. Patients are advised to cooperate with the doctor for surgery as soon as possible after the discovery of a cavernous hemangioma of the brain of 1.4mm, making sure that the surgery is required to be thorough, or else there will be a risk of recurrence.
