Learning objectives Infantile hemangiomas (IHs) are the most common benign tumors of infancy, typically occurring <6 months of age [1]. They have a distinct natural history which consists in early proliferative, quiescent plateau and involution phases. Medical imaging plays an important role in avoiding misdiagnosis (such as fibrous and lipomatous tumors for examples of benign tumors that can mimic IHs or rhabdomyosarcoma, infantile fibrosarcoma, neuroblastoma and lymphoproliferative disorders for examples of malignant neoplasms) and unnecessary procedures [2]. The aim of this paper...
Read more Background Most infantile hemangiomas are present in the skin, but they can occur in the viscera such as liver or gastrointestinal system [3].The natural history of infantile hepatic hemangiomas consists in a rapid, proliferative growth phase for the first six months of life, followed by regression and involution [1].Screening for liver IHs by ultrasonography is recommended when 5 or more cutaneous IHs are noted. However, the majority of IHHs are discovered as incidental findings during routine imaging [3].Imaging characteristics that were...
Read more Findings and procedure details The diagnosis is firstly made with USG and then supported with contrast enhaced CT.The hemangiomas were well-defined hypoechoic lesions on sonography. In one case of diffuse hemangiomatous involvement of the liver, sonography showed the liver to be enlarged and heterogeneous in echo textures. Calcifications and widening of blood vessels were also seen on sonography. Common hepatic artery, celiac trunk, intermediate hepatic vein and aorta in retrocrural space were dilatated.Characteristic CT features for the diagnosis of IHH consist in: peripheral contrast...
Read more Conclusion Infantile hepatic hemangioma (IHH) can be diagnosed on a single phased portal venous CT when they demonstrate all of the typical enhancement features (peripheral, nodular, and discontinuous enhancement).They require close monitoring with serial ultrasounds and generally do not require specific intervention and only needing supportive treatment focussing on the complications.In asymptomatic patients treatment is not required and follow up is usually reserved for HH of more than 5 cm in diameter at 6-12 months to asses for rapid growth with the same imaging test...
