    Low-grade vascular neoplasia of the liver (LGVNL) includes hepatic small vessel neoplasms (HSVN) and anastomosing hemangiomas (AH).

  • 2

    Histopathologically, LGVNL is characterized by small vascular channels with minimal atypia and low proliferative activity, distinguished by infiltrative borders in HSVN.

  • 3

    The prognosis of LGVNL remains unclear, with limited follow-up data and no reported cases of recurrence or metastasis, except one unconfirmed case.

  • 4

    Imaging features of LGVNL include thick peripheral lobulated arterial phase enhancement, often leading to misdiagnosis as other liver lesions.

  • 5

    This multicenter study aimed to describe the imaging characteristics of pathologically confirmed LGVNL using dynamic CT and MRI.
