The delineation and characterization of splenic lesions and other abnormalities can be challenging on computed tomography. Many splenic lesions are incidentally found, imaging features tend to overlap, and without the appropriate clinical context, differentials can range from benign to malignant. Radiologists should be familiar with the wide variety of pathologies seen on computed tomography as it is often the first imaging modality a splenic lesion is seen. The purpose of this MDCT-focused review is to understand normal splenic anatomy and its variants, to illustrate and describe typical and atypical imaging patters of inflammatory, infectious, vascular, traumatic, benign, and malignant tumors of the spleen and provide clues in reaching the appropriate differential diagnosis and management.
在计算机断层扫描（CT）上，脾脏病变和其他异常的描绘和特征具有一定挑战性。许多脾脏病变是偶然发现的，影像学特征往往存在重叠，如果没有适当的临床背景，鉴别诊断范围可以从良性到恶性。放射科医生应该熟悉 CT 上所见的各种病理学表现，因为它通常是脾脏病变的首选影像学检查方法。本 MDCT 重点综述的目的是了解正常脾脏解剖结构及其变异，阐明并描述脾脏炎症、感染、血管、创伤、良性和恶性肿瘤的典型和非典型影像学模式，并提供有助于得出适当鉴别诊断和治疗的线索。
