Rapidly involuting congenital hemangioma RICH and non-involuting congenital hemangioma NICH. A frequent type of atypical hepatic hemangioma is a lesion with an echoic border at ultrasonography. There are three main types of hemangioma.
Less frequent types are large heterogeneous hemangiomas. Most hemangiomas occur on the surface of the skin or just beneath it. There are different kinds of hemangiomas and the most common types are called capillary cavernous and lobular capillary.
Before the year 2000 these lesions were grouped in with infantile hemangiomas. Congenital hemangiomas are usually divided into two groups. Cavernous and capillary Cavernous more common.
Capillarycavernous lobular capillary cellular and epithelioid. The most common hemangioma of the lumbar spine and a hemangioma of the thoracic.
