Cavernous hemangiomas located in the brain or spinal cord are referred to as cerebral cavernomas or more usually as cerebral cavernous malformations (CCMs), [13] [2] and can be found in the white matter, but often abut the cerebral cortex. When they contact the cortex, they can represent a potential seizure focus for the patient.
An infantile hemangioma (IH), sometimes called a strawberry mark due to appearance, is a type of benign vascular tumor or anomaly that affects babies. [1] [2] Other names include capillary hemangioma, [6] "strawberry hemangioma", [7]: 593 strawberry birthmark [8] and strawberry nevus. [6] and formerly known as a cavernous hemangioma.
A cavernous liver hemangioma or hepatic hemangioma is a benign tumour of the liver composed of hepatic endothelial cells. It is the most common liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging. Liver hemangiomas are thought to be congenital in origin. [10]
Cerebral cavernous malformation (CCM) is a cavernous hemangioma that arises in the central nervous system.It can be considered to be a variant of hemangioma, and is characterized by grossly large dilated blood vessels and large vascular channels, less well circumscribed, and more involved with deep structures, with a single layer of endothelium and an absence of neuronal tissue within the lesions.
Infantile hemangioma is the most common vascular tumor. It is a benign tumor, which occurs in 4-5% of Caucasian infants, but rarely in dark skinned infants. [6] It occurs in 20% of low weight premature infants and 2.2 to 4.5 times more frequently in females. [7]
Certain types of headaches may be a sign of a more serious condition, such as a brain tumor or aneurysm, especially if the pain is sudden or severe, according to Cohen. "This highlights the ...
Cavernous lymphangiomas are generally present at birth, but may appear later in the child's life. [6] These bulging masses occur deep under the skin, typically on the neck, tongue and lips, [ 7 ] and vary widely in size, ranging from as small as a centimeter in diameter to several centimeters wide.
Congenital hemangiomas are present and fully formed at birth, [5] and only account for 2% of the hemangiomas. They do not have the postnatal phase of proliferation common to infantile hemangiomas. [6] There are two main variants of congenital hemangioma: non-involuting, and rapidly involuting (beginning in the first year of life). [6]
