Classification | Tumour | Clinical context | Imaging features | Associated lesions |
---|---|---|---|---|
Vascular tumour Benign | Pyogenic granuloma (lobular capillary haemangioma) | Occurs at the site of trauma; occur in up to 5% of pregnancies | Small, exophytic, and hypervascular tumour; increased blood flow | Â |
Vascular tumour Benign | Intramuscular haemangioma | Young adults | Lobulated intramuscular hypervascular mass with non-vascular tissue (fat) | Â |
Vascular tumour Benign; can evolve to an angiosarcoma | Spindle cell haemangiomas in Maffucci syndrome | Non-hereditary mesodermal dysplasia | Cavernous vascular spaces that sometimes contain phleboliths | Enchondromatosis |
Vascular tumour Benign | Intravascular papillary endothelial hyperplasia (Masson’s tumour) |  | Mimics the imaging characteristics of the associated vascular lesions |  |
Vascular tumour Benign | Epithelioid haemangioma | Affects peripheral medium-sized muscular arteries | Hypervascularised tumour developed in the arterial wall | Â |
Vascular tumour Borderline | Kaposi's sarcoma | HIV infection | Hypervascularised tumour of the skin | Bone lesions in 85% of the cases |
Vascular tumour Malignant | Angiosarcoma | Chronic lymphoedema; Maffucci syndrome | Highly aggressive tumour | Chronic lymphoedema; Maffucci syndrome |
Perivascular tumour Menign (malignant tumours are uncommon) | Glomus tumour | Mostly affects women Painful lesion In the nail bed (up to 90%) | Hypervascularised tumour; less than 1Â cm wide; affecting the fingers, usually in the nail bed | Â |
Perivascular tumour Benign | Angioleiomyoma | Painful in 50% of the cases | Homogeneous, hypervascularised tumour; less than 3Â cm large; in the subcutaneous tissue; may be connected to a vessel | Â |
Perivascular tumour Benign | Myopericytoma | Â | Homogeneous and hypervascularised tumour, less than 2Â cm large, in the subcutaneous tissue; may be connected to a vessel | Â |
