Cystic Pancreatic Lesions

AbstractPancreatic cysts are commonly seen with increasing use of cross-sectional imaging. They range from a benign inflammatory process that can produce pseudocysts to malignant lesions such as mucinous cystadenocarcinoma. Other common pancreatic cysts include intraductal pancreatic mucinous neoplasms and serous cystadenomas. Optimized imaging protocol dedicated to imaging the pancreas is required, such as multiphasic computed tomography, magnetic resonance imaging/magnetic resonance cholangiopancreatography, or endoscopic ultrasound, to fully detect and characterize the lesions. A confident diagnosis can be made on imaging when features such as calcifications, pancreatic duct diameter, main duct communication, and mural nodules are assessed. Additionally, pathologic evaluation from fluid/tissue sampling aid in diagnosis. Optimal management of pancreatic cysts is achieved based on the imaging features, conveying key findings in the radiology report, pathologic evaluation, and clinical factors.

The detection of vaginal lesions has increased with the expanding use of cross-sectional imaging. Magnetic resonance imaging (MRI)—with its high-contrast resolution and multiplanar capabilities—is often useful for characterizing vaginal masses. Vaginal masses can be classified as congenital, inflammatory, cystic (benign), and neoplastic (benign or malignant) in etiology. Recognition of the typical MR imaging features of such lesions is important because it often determines the treatment approach and may obviate surgery. Finally, vaginal MR imaging can be used to evaluate post-treatment changes related to previous surgery and radiation therapy. In this article, we will review pertinent vaginal anatomy, vaginal and pelvic MRI technique, and the MRI features of a variety of vaginal lesions with pathological correlation.

AbstractBackground:Isolated olfactory dysfunction is a common complaint; the vast majority of cases are benign and untreatable. A common dilemma is whether to image the olfactory tract of affected patients.Methods:A case review of 100 consecutive patients who underwent magnetic resonance imaging for the primary complaint of olfactory dysfunction was performed. Patients with a diagnosis of chronic rhinosinusitis, with or without nasal polyps, were excluded.Results:Magnetic resonance imaging abnormalities that were considered clinically relevant to the presentation of olfactory dysfunction were found in only seven patients (7 per cent). Of these, only one patient (1 per cent) had an abnormality found that altered their clinical management. A comparison of the findings for children (less than 16 years old,n = 5) with those for adults (equal to or more than 16 years old,n = 95) revealed that 4 per cent of adults scanned had olfactory-related pathology diagnosed, as opposed to 60 per cent of children.Conclusion:Cross-sectional imaging may not be necessary in most patients with olfactory dysfunction. Imaging adds little to the patient history and clinical examination findings.

Small bowel malignancies are rare neoplasms, usually inaccessible to conventional endoscopy but detectable in many cases by cross-sectional imaging. Modern multidetector computed tomographies permit accurate diagnosis, complete pretreatment staging, and follow-up of these lesions. In this review, we describe the cross-sectional imaging features of the most frequent histologic subtypes of the small bowel malignancies.

INTRODUCTION: Jaundice means yellow due to the yellowish discolouration of skin, sclera, and mucous membrane seen in jaundice caused by bilirubin pigment. It is divided in to two forms obstructive(surgical) and non- obstructive (non-surgical). AIM AND OBJECTIVE: To evaluate patients of obstructive jaundice by sonography and magnetic resonance cholangiopancreatography and compare the reporting and ndings by both the modalities. MATERIALS AND METHODS: Cross sectional observational study done from November 2018 to October 2020 and consists of 32 patients who had clinical jaundice and consented to being subjected to both ultrasound and MRCP. OBSERVATIONS:Both USG and MRCP were able to detect extrahepatic CBD dilatation equally in 25 patients. In 5(15.6%) patients USG and MRI both demonstrated intrahepatic mass causing obstruction at the level of conuence of right and left hepatic duct or CHD. Ultrasonography was able to detect the intrinsic mass of the extrahepatic common bile duct in 2(6.2%) patients out of 32 patients in our study population. MRCP could detect the same in 6(18.7%) patients. In our study narrowing of CBD with stricture formation and upstream dilatation of biliary tree was identied in 10(31.2%) patients on MRCP. Ultrasound could diagnose the same in one patient. Both USG and MRCP were able to detect pancreatic head mass as well as pseudocyst. CONCLUSION: The accuracy of MRCP was found to be comparable to that of ERCP for diagnosis of etiology for obstructive jaundice. MRCP allows better lesion characterization and assessment. However, the patchy availability of MR machines become the main achilles heel for the surgeons as well as the radiologists. Hence the valuable role of the omnipresent ultrasonography become immense.

With the steep increase in the use of cross-sectional imaging in recent years, the incidentally detected adrenal lesion, or "incidentaloma", has become an increasingly common diagnostic problem for the radiologist, and a need for an approach to classifying these lesions as benign, malignant or indeterminate with imaging has spurred an explosion of research. While most incidentalomas represent benign disease, typically an adenoma, the possibility of malignant involvement of the adrenal gland necessitates a reliance on imaging to inform management decisions. In this article, we review the literature on adrenal gland imaging, with particular emphasis on computed tomography, magnetic resonance imaging, and photon-emission tomography, and discuss how these findings relate to clinical practice. Emerging technologies, such as contrast-enhanced ultrasonography, dual-energy computed tomography, and magnetic resonance spectroscopic imaging will also be briefly addressed.

Pancreatic cystic lesions are very prevalent, especially in elderly patients and are increasingly being diagnosed because of the massive use of cross sectional imaging. Our knowledge about the natural history of these lesions is limited, especially in the case of intraductal papillary mucinous neoplasms. This fact explains why scientific societies guidelines statements are based on evidence graded as very low quality and helps the understanding of some of the different guidelines recommendations. Several guidelines have been recently revised to incorporate the new evidence published in the literature with the aim to help clinicians make the best decisions. American Gastroenterological Association guidelines, a revision of the International Consensus Guidelines, the American College of Gastroenterology and the European Study Group guidelines are the most recent. Herein we review the current guidelines on pancreatic cysts and focus our discussion on controversies and updates about the best imaging modalities, the indications for endoscopic ultrasound guided fine needle aspiration, cyst fluid analysis, indications for resection and surveillance strategies.

Protocol Study

Objectives: Adrenal adenoma with myelolipomatous degeneration (AMD) is a rarely reported and often overlooked entity. The aim of this study is to improve understanding of these lesions by characterizing the imaging findings with pathologic and clinical correlation. Methods: In the largest series to date, we report 11 nodules in 11 patients confirmed with a pathologic diagnosis of AMD. The available cross-sectional imaging and histopathologic features were reviewed by two radiologists and two pathologists, respectively. Clinical and laboratory data for each patient were obtained from the electronic medical records, when available. Results: All 11 patients had a CT prior to resection or biopsy of the adrenal nodule, with five having received an adrenal mass protocol study. An MRI was available in three patients. The median size of the nodules on imaging was 4.5 cm (range 2.8–8.7) and all but one had macroscopic fat. The largest focus of macroscopic fat had a median size of 0.7 cm (range 0.2–1.6) and on average was 14.4% the size of the tumor, using greatest dimensions. Four (36.4%) patients had a diagnosis of Cushing syndrome prior to nodule resection. Conclusions: Not all adrenal nodules with macroscopic fat on imaging are pure myelolipomas. An AMD should be considered, especially if the foci of fat are small and other features an adenoma are present. Some may also be associated with Cushing syndrome. Advances in knowledge: Myelolipomatous degeneration within an adrenal adenoma has only rarely been previously reported with very few reports emphasizing the imaging features. There may be an association with cortisol hypersecretion and improved recognition of this entity could lead to changes in clinical management.

General Appearance

The general appearance of peritoneal carcinomatosis at abdominal CT and other cross-sectional imaging modalities consists of varying amounts of peritoneal-based soft tissue implants (mass-forming or infiltrative), peritoneal fluid, and occasionally calcification. However, a wide variety of common and uncommon neoplastic and non-neoplastic conditions can closely mimic peritoneal carcinomatosis at imaging. Neoplastic mimics of peritoneal carcinomatosis include primary peritoneal and sub peritoneal tumors, as well as peritoneal lymphomatosis and sarcomatosis. Broad categories of non-neoplastic mimics of peritoneal carcinomatosis include tumor-like conditions, systemic processes, atypical infections, and fat-based conditions. For many entities, suggestive or specific patient information and/or CT imaging findings exist that may allow the radiologist to narrow the differential diagnosis. In this article, we review the salient clinical and cross-sectional imaging features of non-neoplastic mimics of peritoneal carcinomatosis and malignancy, with emphasis on the CT findings and the additional clues that may suggest the correct benign diagnosis.
