“…Although previous studies have indicated that imaging data is an essential basis for diagnosing IPAS [7,36,37], in our case, CT, MRI, PET-CT, and EUS were not good for the differential diagnosis of IPAS. The previous studies found that IPAS should be considered when a smooth, round, solid hypervascular mass appears in the tail of the pancreas on abdominal CT [11,38].…”

Objective:Rare disease Background:Intrapancreatic accessory spleen, or splenunculus, is a congenital condition that occurs in up to 2% of the population, with the tail of the pancreas being the second most common site. Imaging alone may not confirm the diagnosis as this can mimic a hypervascular tumor on contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI). This report presents a challenging case of intrapancreatic accessory spleen in the tail of the pancreas in a 64-year-old man. Case Report:A 64-year-old man was admitted for a space-occupying lesion in the tail of the pancreas. CT, MRI, and positron emission tomography-CT could not confirm the diagnosis. Endoscopic ultrasound-guided fine-needle aspiration biopsy was not performed given the potential for greater risk. The mass in the patient's pancreatic tail was considered benign or low-grade malignant. The patient then underwent a robotic pancreatectomy to remove the tumor in the tail of the pancreas. We performed intraoperative ultrasound scanning and detected a hypoechoic nodule in the body of the pancreas. This nodule had a clear boundary, and color Doppler flow imaging showed that there was no definite blood flow signal in it. The pathology diagnosis after surgery was intrapancreatic accessory spleen. The patient recovered without other complications and was discharged 5 days later. Conclusions:This report highlights the importance of considering the diagnosis of intrapancreatic accessory spleen in hypervascular lesions seen on imaging alone and of confirming the diagnosis with definitive cytopathology or histopathology.

“…Ultrasound examination, combined with CEUS, MRI and PET/CT revealed to be highly accurate methods in the diagnosis and differentiation of IPAS and small solid pancreatic tumors. [16][17][18][19][20] IPAS is an asymptomatic lesion and surgical treatment and histopathological confirmation may not be needed if diagnostic imaging highly suggests IPAS in children. There is significant importance in differentiating IPAS from pancreatic malignant tumors.…”

Background. Intrapancreatic accessory spleen is a congenital abnormality with duplicated splenic tissue located in ectopic sites. Case. We report a case of 10-year-old male patient with an infrequent finding of intrapancreatic mass. The examination of complete blood count, biochemistry, tumor markers were within the normal reference ranges. Imaging series found an intrapancreatic mass without wash-out effect on contrast-enhanced ultrasound, MRIintensity equal to splenic one and no increased glucose metabolism on PET/CT. Follow-up of the patient did not demonstrate progression of the size or change of ultrasound characteristics of the lesion. Conclusions. Intrapancreatic accessory spleen is an asymptomatic lesion and without the need of surgical therapy. It is important to differentiate it from pancreatic malignant tumors.
