  2. Vertebral hemangioma - Wikipedia

    en.wikipedia.org/wiki/Vertebral_hemangioma

    The presence of high or moderate signal intensity on both T1 and T2 images is related to the ratio of fat to vessels and edema. For example, a VH with a high concentration of fat and a relatively low make-up of vessels and edema would show a high signal intensity on T1-weighted spin-echo images and intermediate signal intensity on T2-weighted ...

    en.wikipedia.org/wiki/Polka_dot_sign

    The polka dot sign is a radiological finding most commonly observed on axial computed tomography (CT) or magnetic resonance imaging (MRI) scans of the spine. [1] It is a hallmark feature of vertebral hemangiomas, a benign vascular tumor of the vertebral body.

  4. Hemangioma - Wikipedia

    en.wikipedia.org/wiki/Hemangioma

    A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. The most common form, seen in infants, is an infantile hemangioma , known colloquially as a "strawberry mark", most commonly presenting on the skin at birth or in the first weeks of life.

  5. Vascular tumor - Wikipedia

    en.wikipedia.org/wiki/Vascular_tumor

    Congenital hemangiomas can also be distinguished from infantile hemangiomas in that neither variant of congenital hemangioma expresses the glucose transporter GLUT 1. [6] [9] Some cases have been associated with a mild form of thrombocytopenia. Rare cases have been associated with heart failure. [6]

    Cavernous hemangiomas (also called hepatic hemangioma or liver hemangioma) are the most common type of benign liver tumor, found in 3%– 10% of people. [2] They are made up of blood clusters that are surrounded by endothelial cells. [5] These hemangiomas get their blood supply from the hepatic artery and its branches. [5]

    Angiolymphoid hyperplasia with eosinophilia (also known as: [1] "Epithelioid hemangioma," "Histiocytoid hemangioma," "Inflammatory angiomatous nodule," "Intravenous atypical vascular proliferation," "Papular angioplasia," "Inflammatory arteriovenous hemangioma," and "Pseudopyogenic granuloma") usually presents with pink to red-brown, dome-shaped, dermal papules or nodules of the head or neck ...

  8. Cavernous hemangioma - Wikipedia

    en.wikipedia.org/wiki/Cavernous_hemangioma

    Cavernous hemangioma, also called cavernous angioma, venous malformation, or cavernoma, [1] [2] is a type of venous malformation due to endothelial dysmorphogenesis from a lesion which is present at birth. A cavernoma in the brain is called a cerebral cavernous malformation or CCM.

  9. Focal nodular hyperplasia - Wikipedia

    en.wikipedia.org/wiki/Focal_nodular_hyperplasia

    In the arterial phase CT or MRI, there is a strong enhancement not followed by washout. The lesion presents a slight hyperintensity or isodensity on portal venous phase or delayed phase images. There is also a presence of a central scar and absence of a capsule for the focal nodular hyperplasia. [7]
