Hemangioma is the most common benign congenital neoplasm. It is classified as superficial (formerly known as capillary) or deep (formerly known as cavernous). Deep hemangiomas are located in the subcutaneous tissue and can occur in the brain. Brain hemangioma may lead to cognitive impairment including poor planning and cognitive inflexibility (e.g., Peru et al. 2004). The formation of platelet clots is due to blood vessel tortuosity and hemorrhage. Magnetic resonance signal of T1 hyperintense perilesional signal abnormality has been shown to help differentiate deep hemangiomas from hemorrhagic tumors and intracerebral hemorrhages. Etiology is unknown. Treatment options vary, and the decision to intervene or not remains controversial (Lam and Williams 2002). A promising nonsurgical therapy might be propranolol (e.g., Moodley et al. 2015).
