Quantitative MRI of Pancreatic Cystic Lesions: A New Diagnostic Approach.

Healthcare (Basel) 2022 Jun 2;10(6). Epub 2022 Jun 2.

Department of Medical Imaging, "Iuliu Hațieganu" University of Medicine and Pharmacy Cluj-Napoca, 400012 Cluj-Napoca, Romania.

The commonly used magnetic resonance (MRI) criteria can be insufficient for discriminating mucinous from non-mucinous pancreatic cystic lesions (PCLs). The histological differences between PCLs' fluid composition may be reflected in MRI images, but cannot be assessed by visual evaluation alone. We investigate whether additional MRI quantitative parameters such as signal intensity measurements (SIMs) and radiomics texture analysis (TA) can aid the differentiation between mucinous and non-mucinous PCLs.

Cureus 2021 Nov 10;13(11):e19452. Epub 2021 Nov 10.

General Surgery, All India Institute of Medical Sciences, Raipur, IND.

Lymphangiomas are uncommon benign malformations that can occur anywhere in the body. These are hamartomatous malformations with lymphatic differentiation, which uncommonly involve the abdomen and rarely the pancreas. The size of the cysts in pancreatic lymphangioma directly correlates with the clinical manifestations; however, most of them are non-specific. Read More

World J Gastroenterol 2021 Sep;27(34):5700-5714

Division of Gastroenterology, Hepatology and Endoscopy, Brigham and Women's Hospital, Boston, MA 02115, United States.

Incidental pancreatic cysts are commonly encountered with some cysts having malignant potential. The most common pancreatic cystic neoplasms include serous cystadenoma, mucinous cystic neoplasm and intraductal papillary mucinous neoplasm. Risk stratifying pancreatic cysts is important in deciding whether patients may benefit from endoscopic ultrasound (EUS) or surgical resection. Read More

Department of Gastrointestinal and General Surgery, Tribhuvan University Teaching Hospital, Kathmandu, Nepal.

Mixed serous-neuroendocrine neoplasm constitutes pancreatic serous cystic neoplasms and pancreatic neuroendocrine tumor, two tumor components with different underlying pathologies. The differentiation of these tumors is important as the management and prognosis depend on the pancreatic neuroendocrine tumor component. We report a case of mixed serous-neuroendocrine neoplasm in a 47-year-old female who presented with epigastric pain abdomen for two years. Read More

Cystic pancreatic lesions: MR imaging findings and management.

Insights Imaging 2021 Aug 10;12(1):115. Epub 2021 Aug 10.

Department of Radiology, Regional Hospital Ca' Foncello, Piazza Ospedale 1, 3100, Treviso, Italy.

Cystic pancreatic lesions (CPLs) are frequently casual findings in radiological examinations performed for other reasons in patients with unrelated symptoms. As they require different management according to their histological nature, differential diagnosis is essential. Radiologist plays a key role in the diagnosis and management of these lesions as imaging is able to correctly characterize most of them and thus address to a correct management. Read More

Michelle D Reid

Arch Pathol Lab Med 2022 03;146(3):280-297

From the Department of Pathology and Laboratory Medicine, Emory University School of Medicine, Atlanta, Georgia.

Context.—: Because of new and improved imaging techniques, cystic/intraductal pancreatobiliary tract lesions are increasingly being discovered, and brushings or endoscopic ultrasound/computed tomography/magnetic resonance imaging-guided fine-needle aspiration biopsies from these lesions have become an integral part of pathologists' daily practice. Because patient management has become increasingly conservative, accurate preoperative diagnosis is critical. Read More

A Novel Treatment for Metastatic Serous Cystadenocarcinoma Using a Microwave Ablation: Case Report and Review of the Literature.

Pancreas 2021 03;50(3):434-440

From the Division of Surgical Oncology, Department of Surgery.

Abstract: The incidence of pancreatic cystic neoplasms has grown because of increased detection. Among these lesions, serous cystadenoma was traditionally thought to be universally benign and indolent. However, there is an exceedingly rare malignant variant of serous cystadenoma known as serous cystadenocarcinoma (SCAC) that can exhibit local invasion into adjacent structures, hepatic implants, and metastatic spread to the abdominal viscera.

Abdom Radiol (NY) 2021 04 9;46(4):1629-1639. Epub 2020 Oct 9.

Russell H. Morgan Department of Radiology and Radiological Sciences, Johns Hopkins University School of Medicine, 600 N Wolfe St, Room 143, Baltimore, MD, 21287, USA.

Purpose: To evaluate the use of volumetric multiparametric MRI in differentiating pancreatic intraductal papillary mucinous neoplasms (IPMNs) from serous cystadenomas (SCAs) METHODS: Included patients (123 patients with pancreatic cystic neoplasms (PCNs) measuring ≥ 10 mm) were stratified into two groups based on cyst type. Axial cyst size, region of interest (ROI)-based apparent diffusion coefficient (ADC) and volumetric data, including cyst volume, volumetric apparent diffusion coefficient (vADC), and volumetric venous enhancement (vVE) were extracted and compared between the two groups. Univariate and multiple logistic regression was used to develop models for distinguishing between IPMNs and SCAs. Read More
