Neuroendocrine neoplasm (NEN) and metastasis from renal cell carcinoma are the most common differentials and intrapancreatic accessory spleen (IPAS) is the rarest of its differential diagnosis. We present, here, a case of a 56-year-old man with a space-occupying lesion in body\/tail of pancreas that was preoperatively diagnosed as a NEN based on elevated chromogranin levels and hyperenhancing lesion on contrast-enhanced CT scan. He underwent a spleen-preserving distal pancreatectomy.
