Rong-Xing Zhou, Hai-Jie Hu, Wen-Jie Ma, Yong Jiang, Fu-Yu Li
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...

BACKGROUND: Inspissated cyst fluid may be identified on pancreatic cyst aspiration cytology. We report on the cytomorphologic characteristics of inspissated cyst fluid on EUS-FNA of pancreatic cysts and correlate this finding with histopathology or multimodal (cytology, cyst fluid analysis, molecular pathology, imaging) classification of cyst type. METHODS: The department archives were searched for pancreatic cyst fine-needle aspiration biopsies that contained dessicated, crystalline or inspissated material on cytologic preparations...

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...

INTRODUCTION: Bleeding from isolated gastric varices, though uncommon, may be life threatening and may occur as a consequence of splenic vein thrombosis by tumoral compression and subsequent left-sided portal hypertension. CASE OVERVIEW: We report the case of a 37-year old woman, previously diagnosed with a benign pancreatic cyst, who presented with severe gastric variceal bleeding. DIAGNOSIS, THERAPEUTICS INTERVENTIONS, AND OUTCOMES: Abdominal ultrasound (US) and computed-tomography (CT) revealed enlargement and changed morphology of the cystic tumor located on the body of the pancreas...

A 68-year-old woman was referred to our hospital for the treatment of bile duct stone, pancreatic tumor, and pancreatic cysts. First, bile duct stone was removed using endoscopic retrograde cholangiopancreatography. By abdominal contrast-enhanced computed tomography, a 12-mm diameter tumor was found in the pancreatic body. The tumor was isodense compared with the surrounding pancreatic parenchyma in the non-contrast phase and poorly enhanced in the arterial phase; it exhibited gradual enhancement from the portal vein phase to the late phase...

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...

Most pancreatic ductal adenocarcinomas (PDAs) show solid growth pattern, but ductal adenocarcinomas may demonstrate intratumoral cystic appearance or accompany peritumoral non-neoplastic cystic lesions, thus mimicking cystic pancreatic tumors on imaging studies. The histopathologic findings for PDA with cystic feature are divided into neoplastic and non-neoplastic cysts. Neoplastic cystic changes include large-duct type cysts (microcystic appearance), neoplastic mucin cysts (macrocystic appearance), colloid carcinomas (mucinous noncystic adenocarcinomas), and degenerative cystic change usually caused by hemorrhagic necrosis of tumor...

Mesenteric masses are infrequent lesions ranging from benign cysts to aggressive malignancies and often present a diagnostic and therapeutic challenge. The mesentery is a frequent recipient of metastases from the gastrointestinal tract, pancreas, and biliary cancers. Primary mesenteric tumors are relatively rare, mostly mesenchymal in origin and benign in nature. Examples include gastrointestinal stromal tumors and smooth muscle tumors. We describe a 50-year-old woman, who presented with a lump in the left hypochondrium along with altered bowel habits of 2 years' duration...

PURPOSE: Predicting the biologic behavior of intraductal papillary mucinous neoplasm (IPMN) remains challenging. Current guidelines utilize patient symptoms and imaging characteristics to determine appropriate surgical candidates. However, the majority of resected cysts remain low-risk lesions, many of which may be feasible to have under surveillance. We herein characterize the most promising and up-to-date molecular diagnostics in order to identify optimal components of a molecular signature to distinguish levels of IPMN dysplasia...

Pancreatic cystic lymphangioma is an extremely rare tumor. The characteristic imaging findings are poorly defined, and distinguishing between this disease and other pancreatic cyst-related tumors is very difficult. We herein report a case of a Japanese woman in her 50s with this lesion, located in the tail of the pancreas. Pancreatic cystic lymphangioma should therefore be considered in the differential diagnosis of pancreatic cystic lesions. Laparoscopic resection can be a useful, minimally invasive surgical approach for treating these cysts as well as for the treatment of benign or low-grade malignant tumors located in the pancreatic body or tail...

Pancreatic dermoid cysts are rare and benign congenital abnormalities of germ cell origin. They occur equally in males and females without age predilection. Though radiographic imaging aids in the diagnosis, most times they are inconclusive and require fine-needle aspiration cytology for confirmation. We report the first case of a dermoid cyst presenting as recurrent pancreatitis in a 49-year-old male. Computed tomography scan, followed by magnetic resonance imaging, showed a complex cystic mass lesion adjacent to the pancreatic tail...
