Hemangiomas are classified by size. Medium-sized hemangiomas of 5 to 10 cm are more easily detected and are more frequently described by imaging. [MRI presentation] On MRI, medium-sized hemangiomas have typical morphological features. These lesions have sharply lobulated borders. The vessels have more typical features on MRI than on CT. low signal on T1WI, high signal on T2WI, and still high signal on long TE sequences, with typical peripheral nodular enhancement in the arterial phase. Gradual centripetal enhancement to total tumor intensification in the delayed phase. A. T2WI fat suppression:high signal, lobulated; B. T1WI isochronous image: low signal; C. Typical peripheral nodular-like intensification; D. Delayed phase: continuous homogeneous intensification is still seen, showing whole-tumor intensification. Pathological manifestations] The hemangioma is lobulated, sharply demarcated from liver tissue, and large vascular luminal spaces are seen, covered with single layer of endothelial cells, different amounts of fibrous tissue separation and inflammatory cells. Differential diagnosis】 Mucinous metastases and rare angiosarcoma.
