Abstract Background An epithelial cyst in an intrapancreatic accessory spleen (ECIPAS) is rare. We report a case of ECIPAS that was treated with robot-assisted distal pancreatectomy with splenectomy. Case presentation The case was a 59-year-old woman who was referred to our hospital after a pancreatic tail tumor was found on computed tomography prior to surgery for small bowel obstruction at another hospital. A cystic lesion in the pancreatic tail was discovered and evaluated by magnetic resonance imaging and endoscopic ultrasonography. Based on clinical and radiological features, mucinous cystic neoplasm was included in the differential diagnosis. The patient underwent robot-assisted distal pancreatectomy with splenectomy. The postoperative course was uneventful. Pathological evaluation revealed a 20-mm ECIPAS in the pancreatic tail. Conclusions If a pancreatic tail tumor is present, ECIPAS should be included in the differential diagnosis. However, preoperative diagnosis is difficult, and a definitive diagnosis is often not obtained until after surgery. Surgery should be minimally invasive. Laparoscopic distal pancreatectomy has become a standard surgical procedure because it is minimally invasive. Robot-assisted surgery is not only minimally invasive, but also advantageous, because it has a stereoscopic magnifying effect and allows the forceps to move smoothly. Robot-assisted distal pancreatectomy may be a good option, when performing surgery for a pancreatic tail tumor.

An epithelial cyst in an intrapancreatic accessory spleen (ECIAS) is rare. We herein report a case of a patient with ECIAS who underwent laparoscopic surgery. A 57-year-old woman was referred to our hospital because of a pancreatic tail tumor. She was asymptomatic, and a physical examination revealed no remarkable abnormalities. The levels of the tumor marker carbohydrate antigen 19-9 (CA19-9) and s-pancreas-1 antigen (SPan-1) were elevated. Ultrasonography showed a well-defined homogeneous cystic tumor. Computed tomography showed a well-demarcated cystic tumor in the pancreatic tail. Magnetic resonance imaging showed that the cystic tumor exhibited low intensity on T1-weighted images and high intensity on T2-weighted images. The cystic tumor was diagnosed as mucinous cystic neoplasm preoperatively. The patient underwent laparoscopic spleen-preserving distal pancreatectomy. A histopathological examination revealed the cyst wall to be lined by stratified squamous epithelium within splenic parenchyma, and the ultimate diagnosis was ECIAS. The postoperative course was uneventful, and the patient was discharged on postoperative day 12. ECIAS is very difficult to diagnose preoperatively. Laparoscopic surgery is a safe and minimally invasive procedure for patients with difficult-to-diagnose pancreatic tail tumor suspected of having low-grade malignancy.

Introduction. Accessory spleens can be found in up to 10% of the population, and their intrapancreatic occurrence is considered uncommon. When present, the intrapancreatic accessory spleen is usually found in the tail of the pancreas in about 1.7% of adult individuals. The infrequent presence of the accessory spleen in the pancreatic tissue could lead to inappropriate diagnosis and hence therapeutic approach, as they are commonly presented as a hypervascular node in the tail of the pancreas on abdominal CT and MRI, mimicking a well differentiated tumor of the pancreas or non-functioning pancreatic neuroendocrine tumor. Case Outline. We present a 70-year-old female in whom a preoperative evaluation finding was highly suggestive of a non-functioning neuroendocrine tumor of the pancreatic tail. We performed spleen preserving laparoscopic distal pancreatectomy, and histopathological examination revealed the intrapancreatic accessory spleen. Conclusion. Although infrequent, the presence of the intrapancreatic accessory spleen must be considered in the differential diagnosis of pancreatic tail tumors.

AbstractThe accessory spleen is a focus of splenic tissue which is separated from the main of the spleen. Although accessory spleens are generally recognized on computed tomography (CT), intrapancreatic accessory spleen (IPAS) may be mistaken for other pancreatic tail lesions. We report a case of IPAS mimicking a pancreatic metastasis on the 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). A 41-year-old with diagnosed breast cancer (invasive ductal carcinoma) woman patient underwent an 18F-FDG PET/CT for metastasis screening and staging. 18F-FDG PET/CT showed a focal uptake in the pancreatic tail. The patient underwent a contrast-enhanced CT and magnetic resonance imaging (MRI) for lesion characterization. The density and intensity of lesion were similar to spleen on all phases and all sequences. The lesion was evaluated as IPAS. The diagnosis was confirmed by endoscopic ultrasound (EUS) biopsy. A case of IPAS positive at 18F-FDG PET/CT could not found in the literature. We present a case of IPAS mimicking a pancreatic metastasis positive at 18F-FDG PET/CT.

Abstract BACKGROUNDPancreatic tail cystic lesions are increasingly encountered in clinical practice, however it is difficult to make a correct diagnosis preoperatively because there are many types of pancreatic neoplastic and non-neoplastic cysts. Epidermoid cyst in an intrapancreatic accessory spleen (ECIPAS) is a rare non-neoplastic cyst and located in the pancreatic tail. Therefore, it should be considered in the differential diagnosis of pancreatic tail cystic lesions. CASE PRESENTATION A 51-year-old man was admitted for investigation of abdominal pain. The physical examination and laboratory tests found no abnormalities, except for an elevation of carbohydrate antigen (CA)19-9. Imaging revealed a 2.6-cm cystic lesion within the pancreatic tail, and the solid component surrounding the cyst was enhanced similarly to those of the splenic tissue. ECIPAS was speculated. With regards to the symptoms and difficulty to completely exclude a malignant tumor, laparoscopic spleen-preserving distal pancreatectomy was performed. The final pathological diagnosis was epidermoid cyst arising from an intrapancreatic accessory spleen. The patient was discharged at day 5 postoperatively after an uneventful recovery. CA19-9 returned to normal after surgery. During 2-years follow-up, there was no evidence of tumor recurrence.CONCLUSIONWe describe typical imaging features of ECIPAS and showed that laparoscopic distal pancreatectomy was safe and effective for treating ECIPAS.
