    Study Notes

    Imaging Modalities for Infantile Hemangioma

    • Ultrasound is the first-line imaging modality due to its non-invasive nature and efficiency in assessing superficial hemangiomas.
    • Magnetic Resonance Imaging (MRI) is utilized for deeper or complex lesions, providing excellent tissue characterization.
    • Computed Tomography (CT) may be used in specific cases, particularly when evaluating vascular involvement or in surgical planning.

    Phases of Growth

    • Proliferative Phase: Rapid growth is observed within the first 3 to 9 months of life.
    • Involuting Phase: The hemangioma gradually decreases in size, often starting around 12 months and may continue until 5-7 years of age.
    • Residual Phase: Some lesions may persist with residual skin changes, pigmentation, or fibrofatty tissue even after involution.

    Clinical Features

    • Presents as a superficial lesion, usually bright red or purplish in color, commonly appearing on the face, scalp, and trunk.
    • Most lesions are asymptomatic but may be accompanied by other cutaneous signs such as surface ulceration, especially in rapidly growing hemangiomas.
    • Hemangiomas can vary in size and may be classified as superficial, deep, or mixed types.

    Complications

    • Potential complications include ulceration, leading to pain and infection.
    • Can cause functional impairments depending on location (e.g., affecting vision if over the eye).
    • Psychological impact on the child due to visible lesions, particularly in socially sensitive areas.

    Management Approach

    • Observation is the primary management for most infantile hemangiomas, particularly those that are asymptomatic and not interfering with function.
    • Pharmacological options might include beta-blockers, such as propranolol, which is effective for larger or problematic hemangiomas.
    • Surgical intervention is reserved for lesions that cause significant complications or cosmetic concerns after involution has occurred.
