Background/Aim: Enhanced mural nodules, which can be visualized using computed tomography (CT), constitute high-risk stigmata in branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs). Conversely, the absence of enhanced mural nodules on preoperative imaging does not exclude malignant risk. The present study aimed to investigate other morphological features as predictors of malignancy in "pure" BD-IPMNs without enhanced mural nodules on CT. Method: This retrospective study included 180 patients with surgically confirmed "pure" BD-IPMNs of the pancreas and no enhanced mural nodules on preoperative CT...

Solid serous cystadenoma of the pancreas is the rarest subtype of serous cystadenoma. Cystic structures are difficult to recognize by imaging studies. In the clinical setting, it is crucial to discriminate a solid serious cystadenoma from other solid pancreatic tumors. The present study reported a case of solid serous cystadenoma in which the magnetic resonance cholangiopancreatography (MRCP) findings were useful for diagnosis and decision-making regarding the surgical strategy, with a review of the previous reports of solid serous cystadenoma...

BACKGROUND: Since the concept of intraductal tubulopapillary neoplasm (ITPN) was introduced in the current World Health Organization classification of tumors, the number of reports of ITPN occurrence has increased gradually. However, ITPN is usually located in the main pancreatic duct, with few reports of a branch duct ITPN. As a result, imaging protocols for the diagnosis of a branch duct ITPN have not been established. CASE PRESENTATION: We report a case of a concurrent presentation of a branch duct ITPN and intraductal papillary mucinous neoplasm (IPMN) in the head of the pancreas, with a superior mesenteric artery (SMA) aneurysm...

This is a case of an epidermoid cyst in an intrapancreatic accessory spleen at the tail of the pancreas. Concurrent epidermoid cyst within the accessory spleen is an exceedingly rare entity. The patient initially presented with abdominal pain, nausea and vomiting. Imaging studies revealed a 3.6 cm cystic mass in the tail of the pancreas that was concerning for a mucinous cystic neoplasm (MCN). The patient underwent a robotic distal pancreatectomy for a suspected diagnosis of MCN, which following histologically examination was found to be an epidermoid cyst of an intrapancreatic accessory spleen...

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...

Few things in radiology are "pathognomonic" in their appearance or presentation. However, having an awareness of those findings which are specific to a certain entity is important when interpreting imaging studies. These classic findings can be identified with many imaging modalities, but no modality provides as many recognizable observations as an MRI. This results from the large variety of pulse sequences that provide high contrast resolution, prior to and following contrast administration. In this article, the most classically recognized abdominal findings are presented including the following: Liver: Cyst, hemangioma, focal nodular hyperplasia, hepatic adenoma, hemosiderosis, hepatocellular carcinoma...

RATIONALE: Pancreatic alveolar echinococcosis (AE) is an exceptionally rare disease; no more than 10 cases have been published to date. It is characterized as extensive local tissue infringement and destruction; thus, extended surgical resection, such as duodenopancreatectomy, is often needed to obtain a negative resection margin so as to improve the long-term outcome and prognosis. PATIENT CONCERNS: A middle-aged Tibetan man was admitted due to a 16-year history of recurrent pain in the right upper abdomen...

BACKGROUND: Lymphoepithelial cysts (LECs) are rare pancreatic cystic lesions. Since LECs are benign, preoperative diagnosis is important to differentiate from a cystic neoplasm and avoid unnecessary surgery. The aim of this study was to identify clinical, radiographic and cytopathologic features associated with LECs. METHODS: A retrospective review was performed of patients diagnosed with LEC between 1995 and 2017 at our hospital. Clinicopathologic and radiographic imaging features were documented...

Cystic neoplasms in the pancreas are encountered frequently on imaging, often detected incidentally during evaluation for other conditions. They can have a variety of clinical and imaging presentations, and similarly, wide-ranging prognostic and treatment implications. In the majority, imaging helps in diagnosis of pancreatic cystic neoplasms (PCNs) and guides management decisions. But, a significant minority of the PCNs remain indeterminate. There have been multiple recent advances in biomarkers and molecular genetics which will likely prove helpful in risk stratification of PCNs...

Purpose To determine the effects of patient age and comorbidity level on life expectancy (LE) benefits associated with imaging follow-up of Bosniak IIF renal cysts and pancreatic side-branch (SB) intraductal papillary mucinous neoplasms (IPMNs). Materials and Methods A decision-analytic Markov model to evaluate LE benefits was developed. Hypothetical cohorts with varied age (60-80 years) and comorbidities (none, mild, moderate, or severe) were evaluated. For each finding, LE projections from two strategies were compared: imaging follow-up and no imaging follow-up...

Intraductal papillary mucinous neoplasms (IPMN) are cystic neoplasms with the potential for progression to pancreatic cancer. Recognized by the global medical community just over two decades ago, IPMN have gained great epidemiological and clinical relevance thanks to the widespread use of cross-sectional abdominal imaging, which has led to a surge in the number of incidental pancreatic cysts being diagnosed. As our understanding of this disease has improved, we now know that some IPMN have a very elevated risk of cancer and require surgical resection, while others are low-risk lesions and can be followed...

Hydatid disease is caused by Echinococcus granulosus. Hydatid cysts are commonly located in the liver and lungs. The occurrence of pancreatic hydatid cysts is very rare, even in endemic areas. Sinistral portal hypertension, which is rarely seen, occurs when a pathological process causes splenic vein occlusion. A 26-year-old male patient presented with abdominal pain. He had a history of operation for hydatid cyst of the lung 15 years ago. A left thoracotomy incision scar was observed during his physical examination...
