The findings of single-level dynamic CT were reviewed in 83 lesions of cavernous haemangioma, 90 lesions of hepatocellular carcinoma, 29 lesions of metastatic tumour and 10 lesions of other hepatic masses in order to see the validity of characteristic findings of hepatic cavernous haemangioma. Well-defined, dense and continuously spreading enhancement (WDCSE) being defined as follows: 1. well-defined contour of enhanced area, 2. the density of maximally enhanced area almost same as that of enhanced vessel and 3. continuously spreading enhancement continuing over 20 seconds, WDCSE was noted definitely in 47 lesions of cavernous haemangioma alone (57%; 77% over 3 cm, 64% between 2 and 3 cm, and 19% under 2 cm in diameter) and, suggestively in 16 lesions of cavernous haemangioma and 4 lesions of hepatocellular carcinoma, but in no lesions of other tumours. WDCSE did not show a high sensitivity for cavernous haemangioma but it had a 100% positive predictive value for the disease. If WDCSE is noticed even in oncology patients with hepatic mass, no further examination may be necessary.
回顾了83例海绵状血管瘤、90例肝细胞癌、29例转移瘤及10例其他肝脏肿块的单层面动态CT表现，以观察肝海绵状血管瘤特征性表现的有效性。明确、浓密且持续扩展强化（WDCSE）定义如下：1.强化区域轮廓清晰；2.最大强化区域的密度与强化血管的密度几乎相同；3.持续扩展强化持续超过20秒。仅在47例海绵状血管瘤（57%；直径超过3 cm者占77%，直径在2至3 cm者占64%，直径小于2 cm者占19%）中明确观察到WDCSE，在16例海绵状血管瘤和4例肝细胞癌中疑似观察到WDCSE，但在其他肿瘤中均未观察到。WDCSE对海绵状血管瘤的敏感性不高，但对该病的阳性预测值为100%。即使在有肝脏肿块的肿瘤患者中观察到WDCSE，也可能无需进一步检查。
