Accessory spleen (AS) is a benign condition, where ectopic spleen tissue can be found elsewhere in the abdomen and pelvis, with approximately 20% of cases located at or in the tail of the pancreas. When discovered on imaging, it can be mistaken for conditions that do require surgical removal, including neuroendocrine tumor, and so accurate diagnosis of AS can prevent unnecessary surgery. Endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) is a commonly performed diagnostic modality that can lead to a confirmatory diagnosis of AS. We present a case of AS diagnosed at our institution by EUS-FNA and review the literature for all reported cases of AS that have been confirmed by EUS-FNA.
副脾（AS）是一种良性疾病，异位脾组织可在腹部和骨盆的其他部位发现，约 20%的病例位于胰腺或胰腺尾部。在影像学检查中，它可能被误诊为需要手术切除的疾病，包括神经内分泌肿瘤，因此准确诊断 AS 可以防止不必要的手术。超声内镜（EUS）引导下细针抽吸（FNA）是一种常用的诊断方法，可以明确诊断 AS。我们报告了我院通过 EUS-FNA 诊断的 1 例 AS 病例，并对所有经 EUS-FNA 证实的 AS 病例进行了文献复习。
