"T1: intermediate signal, between that of muscle and fat"
"T2: hyperintense, although small areas of hypointensity may be present (flow-voids, fibrous tissue, or calcification)"
"T1 C+ (Gd): homogeneous enhancement"
"Cutaneous haemangiomas can present as blanching skin lesions that develop fine telangiectasias, or as a red macule with a blanching halo before they involute. Deep or subcutaneous haemangiomas may appear as bluish nodules or plaques. Extra-cutaneous haemangiomas present as lumps."
"These tumours proliferate through both the growth of existing vessels and de novo blood vessel formation. Haemangioma progenitor cells, endothelial cells, and pericytes are the histologically identified cell types that comprise these lesions. Unlike other vascular tumours, they are GLUT-1 positive."

"These lesions are often initially observed. If treatment is to be enacted, options include anti-angiogenesis medications such as propranolol, embolisation, sclerotherapy, radiotherapy, cryotherapy, laser therapy, and surgical excision 5."
