lifestyle
2

Regular MRI surveillance

Periodic magnetic resonance imaging monitoring to track lesion size, location, and any changes in hemorrhage or edema. Typically involves annual or biennial imaging for stable lesions.

monitoring
3

Surgical resection

Microsurgical removal of accessible cavernous malformations causing symptomatic hemorrhage, seizures, or progressive neurological deficits. Goal is complete excision while minimizing trauma to surrounding tissue.

surgical

Additional treatment options

Stereotactic radiosurgery

Focused radiation therapy targeting the malformation to reduce re-hemorrhage risk in deep or surgically inaccessible lesions. Radiation induces endothelial proliferation leading to eventual obliteration.

procedure

Anticonvulsant therapy

Seizure control medications prescribed when cerebral cavernous malformations cause epileptic activity. Selection depends on seizure type and patient comorbidities.

medication

Activity modification

Avoiding activities that increase intracranial pressure or trauma risk, including contact sports and activities requiring Valsalva maneuver. Patient education on warning signs of hemorrhage.
