We report a case of a 72-year-old man who was referred to our tertiary medical center for endoscopic ultrasound (EUS) evaluation for an incidental 2-cm mass in the tail of the pancreas seen on computed tomography (CT). On EUS, a 22 mm by 13 mm, well-defined hypoechoic mass was identified within the pancreatic tail, and a fine-needle biopsy was performed. Histopathology revealed benign pancreatic parenchyma and the presence of lymphocytes. A technetium-99m sulfur colloid scan was performed, which demonstrated uptake in the pancreatic tail lesion consistent with an intra-pancreatic splenule. This case demonstrates that a splenule or accessory splenic tissue should remain in the differential diagnosis of a pancreatic mass. An accurate diagnosis of pancreatic splenule can preclude surgical resection.
我们报告一例72岁男性患者，因计算机断层扫描（CT）偶然发现胰腺尾部有一个2厘米的肿块，被转诊至我们的三级医疗中心进行内镜超声（EUS）评估。在EUS检查中，在胰腺尾部发现一个22毫米×13毫米、边界清晰的低回声肿块，并进行了细针穿刺活检。组织病理学显示为良性胰腺实质且存在淋巴细胞。进行了锝-99m硫胶体扫描，结果显示胰腺尾部病变有摄取，符合胰腺内副脾表现。该病例表明，副脾或副脾组织应保留在胰腺肿块的鉴别诊断中。准确诊断胰腺副脾可避免手术切除。
