Angiomas are most commonly localized lesions.

May occur internally, with one third of such lesions in the liver.
Cases of infantile liver cavernomas are extremely rare.
Cavernous hemangioma of the eye is more prevalent in women than men and between the ages of 20–40.
Malignant transformation rare, if ever.
Loss of heterozygosity is common in tissue where hemangioma develops.
Hemangiomas result from rapid proliferation of endothelial cells and pericytic hyperplasia, or the enlargement of tissue as a result of abnormal cell division pericytes.
MRI is most sensitive method for diagnosing cavernous hemangiomas.
MRI associated with an increased diagnosis of cavernous hemangiomas.
Asymptomatic lesions may not require treatment but may need to be monitored for any change in the size.
A change in size of lesions in the nose, lips, or eyelids can be treated with steroid drugs to slow its progress.
Steroids can be taken orally or injected directly into the tumor.
