This study will attempt to determine how common liver hemangiomas are in children with infantile hemangiomas by comparing liver ultrasound results in patients with 1-4 cutaneous hemangiomas, 5 or more cutaneous hemangiomas, or at least 1 large hemangioma versus ultrasound results in children without hemangiomas. Other objectives of the study include identifying specific risk factors in patients who have liver hemangiomas and identifying risk factors in children with symptomatic liver hemangiomas.
Hemangioma of infancy is the most common tumor of childhood occurring in 4% to 10% of infants. While most hemangiomas are benign in behavior and involute spontaneously, some can cause significant morbidity due to their location and size. In addition, some hemangiomas may be associated with extracutaneous hemangiomas that result in significant morbidity. Certain "high risk" hemangiomas of infancy, specifically multiple cutaneous hemangiomas or a solitary large hemangioma, have been associated with hepatic hemangiomatosis; however, the exact number or size of the cutaneous lesions at which the risk increases and the protocol for evaluating these patients remain controversial. The true prevalence of hepatic hemangiomatosis is unknown since there have been no large scale prospective studies evaluating clinically asymptomatic patients with cutaneous hemangiomas for the presence of hepatic hemangiomatosis.
One of the primary objectives of this study is to determine the incidence of hepatic hemangiomatosis in patients with hemangiomas of infancy by comparing hepatic ultrasound imaging results of patients with 1-4 cutaneous hemangiomas, 5 or more cutaneous hemangiomas, or at least 1 large hemangioma >30 cm2 versus imaging results in patients without cutaneous hemangiomas. The study will also attempt to identify specific risk factors associated with the development of hepatic hemangiomatosis and to identify associated risk factors in patients with clinically symptomatic hepatic hemangiomatosis.

The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.
A protrusion of abdominal structures through the retaining ABDOMINAL WALL. It involves two parts: an opening in the abdominal wall, and a hernia sac consisting of PERITONEUM and abdominal contents. Abdominal hernias include groin hernia (HERNIA, FEMORAL; HERNIA, INGUINAL) and VENTRAL HERNIA.
A benign neoplasm of pneumocytes, cells of the PULMONARY ALVEOLI. Originally considered to be vascular in origin, it is now classified as an epithelial tumor with several elements, including solid cellular areas, papillary structure, sclerotic regions, and dilated blood-filled spaces resembling HEMANGIOMA.
Surgical removal of excess abdominal skin and fat and tightening of the ABDOMINAL WALL. Abdominoplasty may include LIPECTOMY of INTRA-ABDOMINAL FAT, tightening of the ABDOMINAL MUSCLES, and re-creation of the UMBILICUS.
A dull red, firm, dome-shaped hemangioma, sharply demarcated from surrounding skin, usually located on the head and neck, which grows rapidly and generally undergoes regression and involution without scarring. It is caused by proliferation of immature capillary vessels in active stroma, and is usually present at birth or occurs within the first two or three months of life. (Dorland, 27th ed)
