Imaging features of recently identified low-grade vascular neoplasia of the liver: hepatic small vessel neoplasm and anastomosing hemangioma
Question Low-grade vascular neoplasia of the liver, including hepatic small vessel neoplasms and anastomosing hemangioma, is a new entity of vascular tumors with few radiological descriptions. Findings Diagnostic imaging criteria include the "flower petal shape" enhancement pattern on arterial phase, a marked hypersignal on T2-weighted images and high ADC values. Clinical relevance This multicenter study provides clinical, pathological and imaging data on low-grade vascular neoplasia of the liver and highlights specific imaging features for its diagnosis. Knowledge of these imaging features helps eliminate differential diagnoses.
