Life-Threatening Complications and Intensive Care of Diffuse Neonatal Hemangiomatosis of the Liver in a One-Month-Old Girl: A Case Report.

Background: An infantile hemangioma (IH) is a benign lesion that develops as a result of pathologically dysregulated proliferation of the endothelial cells of the capillaries, typically appearing within the first three years of life. The disease is found mostly on the skin and-less often-in the internal organs. Although IH generally has a good prognosis and may sometimes undergo spontaneous regression, certain types of IH with a specific form, localization, and size may lead to life-threatening conditions including impairment of vital functions. This determines the need for precise diagnostics and treatment. Case presentation: The paper presents a clinical observation of an infant in the first months of life with IH presenting as diffuse hepatic hemangiomatosis and a hemangioma of the left eyebrow area. The IH was associated with life-threatening conditions. However, effective treatment with the non-selective β-adrenoblocker propranolol led to a positive outcome and the resolution of complications. Conclusions: This case demonstrates the critical importance of timely diagnosis and treatment for lesions that, while benign, can lead to fatal complications if not addressed promptly.
