Splenic masses present a diagnostic challenge to radiologists and clinicians alike, with a relative paucity of data correlating radiologic findings to pathological diagnosis in the pediatric population. To illustrate splenic mass imaging findings and approximate lesion prevalence, we retrospectively reviewed all splenectomies and splenic biopsies for splenic masses at a single academic pediatric hospital over a 10-year period in patients 18 years and younger. A total of 31 splenic masses were analyzed. Lesion prevalence, pathology and imaging features associated with sampled splenic masses are described. The lesions encountered include benign splenic cysts (9), vascular anomalies (7), hamartoma (3), leukemia/lymphoma (3), granulomata (3) and metastasis (2). We also identified single cases of angiosarcoma, splenic cord capillary hemangioma, congestive hemorrhage, and benign smooth muscle neoplasm.
脾脏肿块对放射科医生和临床医生来说都是一个诊断难题，因为在儿科人群中，相对缺乏将放射学发现与病理诊断相关联的数据。为了说明脾脏肿块的影像学表现和大致的病变发生率，我们回顾性分析了一家学术性儿科医院在过去 10 年中 18 岁及以下患者因脾脏肿块进行的所有脾切除术和脾活检。共分析了 31 个脾脏肿块。描述了与取样的脾脏肿块相关的病变发生率、病理学和影像学特征。所遇到的病变包括良性脾囊肿（9 个）、血管异常（7 个）、错构瘤（3 个）、白血病/淋巴瘤（3 个）、肉芽肿（3 个）和转移瘤（2 个）。我们还发现了单个血管肉瘤、脾索毛细血管血管瘤、充血性出血和良性平滑肌肿瘤的病例。
