  • Title: Angiographic and Clinical Features of Noninvoluting Congenital Hemangiomas.
    Author: Patel A, De Leacy R, Berenstein A.
    Journal: AJNR Am J Neuroradiol; 2019 May; 40(5):845-848. PubMed ID: 31023659.
    Abstract:
    While infantile hemangiomas are very common, congenital hemangiomas are rare and less understood. Congenital hemangiomas are present at birth. They fall into 2 major categories: rapidly involuting congenital hemangioma and noninvoluting congenital hemangioma. Noninvoluting congenital hemangioma is the rarer of the 2 entities. If not recognized and treated appropriately, noninvoluting congenital hemangioma can lead to considerable morbidity. There is a paucity of literature regarding noninvoluting congenital hemangiomas. In this article, we will outline our experience with this condition, focusing on clinical and angiographic features. There is a distinct angiographic appearance of noninvoluting congenital hemangiomas involving an arterial-capillary web, a dense tumor blush with identifiable feeding arteries, no arteriovenous shunting, and variably present draining veins. Our experience with endovascular embolization and direct percutaneous treatment is the largest for this entity to date. Endovascular embolization and/or direct percutaneous sclerotherapy of this lesion may obviate subsequent surgical resection.
