摘　　要：目的 探讨肾上腺海绵状血管瘤(ACH)的CT表现。方法 回顾性分析7例ACH患者的CT资料,分析指标包括病灶数目、部位、形态、大小、边缘、密度及强化方式。结果 7例ACH中,6例为单发病灶,1例可见2个病灶。所有病灶均位于左侧,呈类圆形,边缘清楚,最大径0.9~4.8 cm[(2.47±1.21)cm]。CT平扫呈等或稍低密度,其中4例(57.1%)病灶内可见钙化,3例表现为弥漫分布于瘤体内的多发点状、颗粒状钙化,1例表现为少许点状、颗粒状钙化。3例(42.9%)增强CT表现为动脉期边缘强化,静脉期强化范围向中央填充;2例病灶表现为动脉期和静脉期实性部分轻度强化;1例病灶因全瘤钙化无法评估强化;1例仅行CT平扫。结论 CT对诊断ACH具有一定价值,其中弥漫分布的点状、颗粒状钙化及早期边缘强化并逐渐向周围填充为其特征表现。Objective To explore the CT imaging findings of adrenal cavernous hemangiomas(ACH).Methods A retrospective analysis was conducted on the CT data of 7 cases with ACH.The analysis imaging findings included the number,location,shape,size,margin,attenuation and enhancement pattern.Results Among the 7 cases of ACH,six had single lesions(6/7)and one(1/7)had two lesions.All of the lesions were located in the left adrenal gland,presenting as round or oval with clear margin,ranging in maximum diameter from 0.9 to 4.8 cm[(2.47±1.21)cm].On unenhanced CT scans,the lesions showed iso-or slightly hypoattenuation features,with 4 cases(57.1%)showing calcification within lesions.Three cases exhibited diffusely distributed multiple punctate or granular calcifications within the lesion,and 1 case showed a few punctate and granular calcifications.On the contrast-enhanced CT,3(42.9%)showed early peripheral enhancement during the arterial phase with filling toward the center during the venous phase;2 cases showed mild enhancement of the solid parts during both arterial and venous phases;one case could not be evaluated for enhancement pattern due to complete tumor calcification.One patient only underwent an unenhanced CT scan.Conclusion CT has certain value in the diagnosis of ACH,with diffusely distributed punctate or granular calcifications and early peripheral enhancement followed by gradual filling-in being characteristic manifestations.
