Abstract
Pancreatic pseudocysts are fluid-filled collections that can arise from acute or chronic pancreatitis and may lead to a range of complications, like rupture, infection, hemorrhage, etc. Morbid obesity may further complicate the diagnosis and management of such cases. The present report describes the case of a 26-year-old superobese female (BMI: 58 kg/m²) with a pancreatic pseudocyst that presented diagnostic challenges and mimicked pulmonary embolism when the pseudocyst had ruptured. The patient initially presented with persistent biliary colic due to gallstones. Despite undergoing laparoscopic cholecystectomy, she continued to experience symptoms, including nausea, bloating, and inability to tolerate food, and lab tests showed progressive elevation of serum bilirubin levels. A huge pancreatic pseudocyst was found to be obliterating the gastric cavity and compressing the common bile duct after the patient was subjected to further radiological imaging. While waiting to be transferred to a tertiary center with endoscopic retrograde cholangiopancreatography (ERCP), endoscopic stenting, and other facilities, she suddenly experienced severe symptoms, like shortness of breath, upper abdominal/chest pain, tachycardia (heart rate: 140 beats per min), dizziness, and low oxygen saturation. The likelihood of pulmonary embolism (PE) was very high in the differential diagnoses, but computer tomography pulmonary angiography (CTPA) ruled out PE. Based on imaging and clinical assessment, rupture of the pancreatic pseudocyst was diagnosed. The patient was subsequently managed in a tertiary hospital endoscopically. This case highlights the challenges of diagnosing and managing pancreatic pseudocysts in extremely obese patients. It also underscores the role of a multidisciplinary approach and vigilant clinical attention to prevent misdiagnosis and optimize outcomes.

Abstract
Fatty infiltration of the pancreas (FIP) has been recognized for nearly a century, yet many aspects of this condition remain unclear. Regular literature reviews on the diagnosis, consequences, and management of FIP are crucial. This review article highlights the various disorders for which FIP has been established as a risk factor, including type 2 diabetes mellitus (T2DM), pancreatitis, pancreatic fistula (PF), metabolic syndrome (MS), polycystic ovary syndrome (PCOS), and pancreatic duct adenocarcinoma (PDAC), as well as the new investigation tools. Given the interdisciplinary nature of FIP research, a broad range of healthcare specialists are involved. This review article covers key aspects of FIP, including nomenclature and definition of pancreatic fat infiltration, history and epidemiology, etiology and pathophysiology, clinical presentation and diagnosis, clinical consequences, and treatment. This review is presented in a detailed narrative format for accessibility to clinicians and medical students.

Oliveira R, Figueiredo L, Costa P. Modification of [18F]-FDG PET/CT imaging protocols in obese oncology patients: A nationwide survey. Radiography (Lond) 2023; 29:145-151. [PMID: 36370640 DOI: 10.1016/j.radi.2022.10.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Revised: 10/23/2022] [Accepted: 10/25/2022] [Indexed: 11/11/2022]
Abstract
INTRODUCTION The use of medical imaging for diagnosis, staging and follow-up in Oncology context is incredibly important, being the use of [18F]-FDG PET/CT particularly advantageous in specific contexts like the case of obese patients. However, imaging the latter can be challenging sometimes, since their own body size may affect overall image quality and adds technical difficulties for the operator(s) performing the examination. METHODS This research project was developed with the aim of analysing the current personal practices of Portuguese Nuclear Medicine Technologists (NMTs) in the adaptation of 18F-FDG PET/CT oncological protocols for obese patients and comparing the results with parameters referenced in literature. A non-experimental research study was conducted using a survey delivered online to NMTs through social media platforms (Facebook® and LinkedIn®) and by sending the link directly to contacts within the research team professional and personal networks. RESULTS Answers from a total of 26 participants were obtained, with 88.5% of participants admitting modifying technical protocols in examinations for obese patients. Changes in PET protocols included an increase in the administered activity (60.9%), an increase in scan time per individual bed position (69.6%) and the use of Time-of-Flight (TOF) technology whenever available. Protocol changes in CT included increasing the mA (82.6%), raising the KVp (47.8%), the application of iterative reconstruction (69.6%) and the use of automatic exposure control (AEC) (52.2%). The remaining parameters (pitch, algorithm, slice thickness, display FOV, gantry rotation time and energy acceptance window) were claimed not to be modified by around 90% of professionals. CONCLUSION Portuguese NMTs tend to change the [18F]-FDG PET/CT protocols for obese patients. However, while some of the parameters appear to be contradictory or redundant, others require further optimisation, especially in the CT component. IMPLICATIONS FOR PRACTICE Efforts should be made to optimize acquisition protocols used in [18F]-FDG PET/CT scans for obese patients.

Radiol Med 2020; 126:445-452. [PMID: 32812173 DOI: 10.1007/s11547-020-01258-z] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Accepted: 08/10/2020] [Indexed: 12/13/2022]
Abstract
OBJECTIVE Quantitative bone marrow (BM) MR sequences, as DWI and CSI, were used to evaluate BM water-fat composition. The aim of the study was to assess the potential usefulness of fat fraction (FF) and ADC, calculated by CSI or DWI, in diagnosing and classifying myeloma (MM) patients according to their different BM infiltration patterns. METHODS The study group included 43 MM patients (19F; 24M; mean age 64 years), 15 asymptomatic, 15 symptomatic with diffuse BM infiltration and 13 symptomatic with focal lesions (FLs). The control group was made up of 15 healthy subjects (7F; 8M; mean age 64 years). MRI examinations consisted of sagittal T1w TSE on the spinal column, axial DWI (b 50-400-800 mm2/s) and coronal T2 Dixon, on the whole body. Mean ADC and FF were calculated placing 1 ROI on 6 vertebras and 2 ROIs on either the pelvis or FL. RESULTS ANOVA with Bonferroni's correction showed a significant difference in ADC values among the different groups of MM patients (P < 0.05), while FF was only significantly different between patients with diffuse infiltration and patients with FL (P = 0.002). ADC allowed distinguishing MM patients from normal BM patients with diffuse BM infiltration (cutoff value: 0.491 × 10-3 mm2/s; sensitivity 73%, specificity 80%). FF helped better discriminate healthy controls from normal BM patients (cutoff = 0.33, sensitivity 73%, specificity 92%) and patients with diffuse BM infiltration from those with FL (cutoff = 0.16, sensitivity 82%, specificity 92%). CONCLUSION ADC and FF are potentially useful parameter for the quantitative evaluation of BM infiltration in MM patients.
