BACKGROUND
More than 10% of healthy population has one or more accessory spleens. The most common location is the hilum of the spleen or area near the tail of the pancreas. The radiological appearance of accessory spleens in oncologic patients who underwent splenectomy can be misinterpreted as a recurrence, especially in the case of compensatory growth of an accessory spleen in successive radiological examinations. CASER REPORTS: We present the cases of three patients who underwent splenectomy for gastric carcinoid, gastric adenocarcinoma and cancer of the left adrenal gland, respectively. CT examination and/or PET-CT scan revealed suspicious findings in the left upper abdomen. In one patient, the dimensional increase of this finding in successive examinations was initially considered suggestive for cancer recurrence. Scintigraphy with (99m)Tc-nanocolloid was able to confirm the presence of an accessory spleen in all these patients.
CONCLUSIONS
Splenic scintigraphy is an economical, accessible and accurate tool in differential diagnosis of accessory spleens in patients after splenectomy.
背景
超过10%的健康人群有一个或多个副脾。最常见的位置是脾门或胰腺尾部附近区域。接受脾切除术的肿瘤患者中副脾的放射学表现可能被误诊为复发，尤其是在连续放射学检查中副脾出现代偿性生长的情况下。病例报告：我们分别介绍了三名因胃类癌、胃腺癌和左肾上腺癌接受脾切除术的患者的病例。CT检查和/或PET-CT扫描显示左上腹有可疑发现。在一名患者中，连续检查中该发现的尺寸增大最初被认为提示癌症复发。用（99m）Tc-纳米胶体进行的闪烁扫描能够在所有这些患者中确认副脾的存在。
结论
脾闪烁扫描是脾切除术后患者副脾鉴别诊断中一种经济、可及且准确的工具。
