Somatostatin receptor imaging findings of pancreatic neuroendocrine tumor with diffuse involvement of the pancreas are rarely reported. We present somatostatin receptor PET imaging findings in 3 cases of diffuse pancreatic neuroendocrine tumor. One case showed diffuse swelling and diffusely intense activity of the pancreas with multiple metastases in the peripancreatic lymph nodes and liver. The other 2 cases showed diffusely intense activity of the pancreas without metastasis. The pancreatic tumor extended into the duodenum in all the 3 cases. Familiarity with this rare pattern of radiotracer uptake in pancreatic neuroendocrine tumor may be helpful for the diagnosis.
胰腺神经内分泌肿瘤弥漫性累及胰腺的生长抑素受体成像结果鲜有报道。我们展示了3例弥漫性胰腺神经内分泌肿瘤的生长抑素受体PET成像结果。1例显示胰腺弥漫性肿大且弥漫性摄取放射性示踪剂增强，伴有胰周淋巴结和肝脏多发转移。另外2例显示胰腺弥漫性摄取放射性示踪剂增强但无转移。所有3例中胰腺肿瘤均延伸至十二指肠。熟悉胰腺神经内分泌肿瘤这种罕见的放射性示踪剂摄取模式可能有助于诊断。
