Imaging features of recently identified low-grade vascular neoplasia of the liver: hepatic small vessel neoplasm and anastomosing hemangioma
To describe the imaging features of pathologically confirmed low-grade vascular neoplasia of the liver (LGVNL) on dynamic CT and MRI, highlighting its clinical significance.
Key Findings:
LGVNL includes hepatic small vessel neoplasms (HSVN) and anastomosing hemangiomas (AH), characterized by small, closely packed vascular channels.
Imaging features typically include thick peripheral lobulated arterial phase enhancement or a 'flower petal shape', which can lead to misdiagnosis.
Misdiagnosis of LGVNL is common, often confused with hepatic cavernous hemangiomas or liver metastases, potentially resulting in inappropriate management.
Interpretation:
The imaging characteristics of LGVNL are not well-defined due to their rarity, leading to potential mismanagement in clinical practice, emphasizing the need for further research.
Limitations:
Limited follow-up data on the prognosis of LGVNL.
Variability in imaging techniques and protocols across different centers may impact the reliability of findings.
Conclusion:
Further characterization of imaging features is essential to improve diagnosis and management of LGVNL, given its potential for misdiagnosis and the implications for patient care.
