Infantile hemangioma is a benign neoplasm of endothelial cells. They commonly develop in neonates within first few months of life. At unenhanced CT, infantile hemangioendothelioma usually manifests as a well-defined mass that is hypoattenuating relative to the normal liver parenchyma (, 8).

Infantile hemangiomas (IHs) are the most common tumors of childhood. Unlike other tumors, they have the unique ability to involute after proliferation, often leading primary care providers to assume they will resolve without intervention or consequence. The fourth radiologist was a senior radiology resident with extensive experience in the imaging characteristics of infantile hepatic hemangiomas. Imaging characteristics that were recorded included distribution of lesions (focal vs multifocal), vascularity of lesions (high flow vs low flow), echogenicity, presence of calcifications, signal The duplex Doppler ultrasound (US) characteristics of 13 infantile hepatic hemangiomas were reviewed to assess the utility of these characteristics in diagnosis and follow-up.

Congenital hemangiomas and infantile hemangioma: Missing links John B. Mulliken, MD,a and Odile Enjolras, MDb Boston, Massachusetts, and Paris, France Rapid postnatal growth and slow involution in childhood characterize the common infantile hemangioma. There are other rare vascular tumors that present fully grown at birth and behave quite Infantile hemangiomas (IHs) occur in as many as 5% of infants, making them the most common benign tumor of infancy.
lium in infantile hemangioma immunostains for glu-cose transporter-1 protein (GLUT1) throughout the tumor’s life cycle. However, other vascular tumors are immunonegative, and these authors have sug-gested that GLUT1 is a specific marker for infantile hemangioma.5 However, neither RICH (with rare exceptions) nor NICH stains with GLUT1 antibod-
We recommend against using the term "hemangioendothelioma" for infantile or congenital hemangioma. The following 2 sections dedicated to infantile hepatic hemangioma and to congenital hepatic hemangioma individually describe these subtypes in further detail, including complications to be considered during monitoring and respectively recommended screening evaluations.

Current Residents 2020 – BIDMC Neurology fotografera. Infantile hemangiomas are predominantly superficial soft-tissue lesions and thus can be easily assessed by ultrasound. They present as an echogenic well-defined mass that may exhibit prominent internal vascularity on color Doppler 1.
Since its unforeseen discovery in 2008, propranolol has become the first-line treatment for infantile hemangiomas, eclipsing systemic corticosteroids and radiologic intervention. There are still, however, uncommon indications for more aggressive interventional management. Infantile hemangiomas are the most common vascular tumors of infancy. A multidisciplinary approach including dermatologists, otolaryngologists, plastic surgeons, hematologists/oncologists and interventional/diagnostic radiologists is crucial for appropriate management of children with complicated infantile hemangiomas.

They commonly develop in neonates within first few months of life. At unenhanced CT, infantile hemangioendothelioma usually manifests as a well-defined mass that is hypoattenuating relative to the normal liver parenchyma (, 8). In about 16%–40% of cases, the lesion is heterogeneous with central high-attenuation areas due to hemorrhage or calcifications ( , 1 , , 7 , , 8 ). Infantile hemangiomas, which are vascular tumors with a specific evolution pattern, constitute a large majority of these lesions. On the other hand, there are vascular malformations, which are anomalies of the vascular system, consisting of a range of vascular tissues associated with various flow patterns. Congenital hemangiomas are benign vascular tumors of childhood that are present at birth.
