Abstract	Intraductal papillary mucinous neoplasms (IPMN) of the pancreas have the potential for malignant progression into adenocarcinoma. Colloid or mucinous non-cystic carcinoma of the pancreas is an uncommon variant neoplasm that can arise within an intestinal type IPMN and have a relatively improved prognosis but may mimic the more lethal tubular or ductal adenocarcinoma. Colloid carcinoma is an infiltrating ductal epithelial neoplasm containing primarily extracellular stromal mucin pools and scant amount of centrally floating neoplastic cells. While several reports have evaluated the unique pathologic and immunohistochemical profile of colloid carcinomas, there has been limited radiologic-pathologic correlation in the literature. We report a case of an 83-year-old female who presented for evaluation of slowly progressive abdominal pain and was found to have colloid carcinoma arising from an IPMN. This is one of the first reports to correlate the multimodality radiology including cinematic rendering (CR) and histopathology features associated with this tumor. An enhanced understanding of the correlation between imaging appearance and specific histopathologic findings may aid in the early recognition and treatment of this rare neoplasm. Emphasis is placed on CR as this may help guide surgical management.

Abstract	In the setting of cardio-oncology, evaluation for myocarditis is a growing indication for cardiovascular magnetic resonance (CMR). Treatment-related side effects of cancer therapies comprise the majority of myocarditis cases in cardio-oncology, and these are often secondary to anthracyclines and even the newer class of immune checkpoint inhibitors. Cardiotoxicity from cancer therapy represents an increasingly recognized etiology of myocarditis and when detected, warrants prompt management changes. The conventional CMR evaluation for myocarditis includes modules for the left ventricular structure and function, early gadolinium enhancement, and late gadolinium enhancement. Newer CMR sequences including native T1 mapping and extracellular volume fraction offer improvement in diagnostic accuracy from conventional CMR methods. We present a case of subacute/ chronic myocarditis related to anthracycline therapy 4 months prior that was diagnosed only after incidental diffuse myocardial calcifications on pre-treatment computed tomography raised suspicion.

Abstract	Testicular cancers are a group of uncommon malignancies that account for less than 1% of new cancer cases per year in the United States and globally. The disease typically affects men between the ages of 20-44, and the overwhelming majority of tumors are germ cell in origin. Most cases of testicular cancer are organ confined at diagnosis and have a good overall prognosis. Testicular cancers are staged by the tumor, node, metastasis, serum markers (TNMS) classification set forth by the American Joint Commission on Cancer staging. Diagnostic imaging plays a crucial role in initial staging, specifically in assessing the primary tumor prior to orchiectomy and evaluating for regional and/or distant metastasis. Multimodality imaging is used for initial staging, with ultrasound and computed tomography (CT) most commonly utilized. Diagnostic imaging is also important in evaluating response in patients who initially present with metastatic disease as well as in patients who are undergoing surveillance. Typically, CT is used for response assessment and surveillance, with magnetic resonance imaging (MRI) and positron emission tomography (PET) serving as adjunct modalities. This article reviews the role of various diagnostic imaging modalities and how they are employed in the diagnosis, staging, response assessment and surveillance of primary testicular cancer.

Abstract	Background: Significant racial disparities in pancreatic cancer incidence and mortality rates exist, with the highest rates in African Americans compared to Non-Hispanic Whites and Hispanic/Latinx populations. Computer-derived quantitative imaging or "radiomic" features may serve as non-invasive surrogates for underlying biological factors and heterogeneity that characterize pancreatic tumors from African Americans, yet studies are lacking in this area. The objective of this pilot study was to determine if the radiomic tumor profile extracted from pretreatment computed tomography (CT) images differs between African Americans, Non-Hispanic Whites, and Hispanic/Latinx with pancreatic cancer. Methods: We evaluated a retrospective cohort of 71 pancreatic cancer cases (23 African American, 33 Non-Hispanic White, and 15 Hispanic/Latinx) who underwent pretreatment CT imaging at Moffitt Cancer Center and Research Institute. Whole lesion semi-automated segmentation was performed on each slice of the lesion on all pretreatment venous phase CT exams using Healthmyne Software (Healthmyne, Madison, WI, USA) to generate a volume of interest. To reduce feature dimensionality, 135 highly relevant non-texture and texture features were extracted from each segmented lesion and analyzed for each volume of interest. Results: Thirty features were identified and significantly associated with race/ethnicity based on Kruskal-Wallis test. Ten of the radiomic features were highly associated with race/ethnicity independent of tumor grade, including sphericity, volumetric mean Hounsfield units (HU), minimum HU, coefficient of variation HU, four gray level texture features, and two wavelet texture features. A radiomic signature summarized by the first principal component partially differentiated African American from non-African American tumors (area underneath the curve = 0.80). Poorer survival among African Americans compared to Non-African Americans was observed for tumors with lower volumetric mean CT [HR: 3.90 (95% CI:1.19-12.78), p=0.024], lower GLCM Avg Column Mean [HR:4.75 (95% CI: 1.44,15.37), p=0.010], and higher GLCM Cluster Tendency [HR:3.36 (95% CI: 1.06-10.68), p=0.040], and associations persisted in volumetric mean CT and GLCM Avg Column after adjustment for key clinicopathologic factors. Conclusions: This pilot study identified several textural radiomics features associated with poor overall survival among African Americans with PDAC, independent of other prognostic factors such as grade. Our findings suggest that CT radiomic features may serve as surrogates for underlying biological factors and add value in predicting clinical outcomes when integrated with other parameters in ongoing and future studies of cancer health disparities.

Abstract	We present the conventional cardiac magnetic resonance (CMR) protocol for evaluating a suspected thrombus and highlight emerging techniques. The appearance of a mass on certain magnetic resonance (MR) sequences can help differentiate a thrombus from competing diagnoses such as a tumor. T1 and T2 signal characteristics of a thrombus are related to the evolution of hemoglobin properties. A thrombus typically does not enhance following contrast administration, which also helps differentiation from a tumor. We also highlight the emerging role of T1 mapping in the evaluation of a thrombus, which can add another level of support in diagnosis. Prior to any CMR exam, patient screening and interviews are critical to ensure safety and to optimize patient comfort. Effective communication during the exam between the technologist and the patient promotes proper breath holding technique and higher quality images. Volumetric post processing and structured reporting are helpful to ensure that the radiologist answers the ordering services' question and communicates these results effectively. Optimal pre-MR safety evaluation, CMR exam execution, and post exam processing and reporting allow for delivery of high quality radiological service in the evaluation of a suspected cardiac thrombus.

Abstract	Neuroendocrine tumor (NET) cardiac metastases can be associated with complications including ventricular outflow obstruction, arrhythmias, heart failure, and cardiac arrest, warranting intervention. Anatomical characterization of these lesions via cardiac magnetic resonance (CMR) is helpful to assess and predict the risk of complications and guide therapy. Images of 2 patients with small bowel NET related cardiac metastases are described on Ga-DOTATATE PET/CT and CMR. The lesions were significantly smaller and more obscure on CMR compared with PET/CT. On CMR, T2-weighted dark blood images and late gadolinium enhancement images offered the most conspicuous detection of the NET myocardial metastases in these cases.

Abstract	Introduction: Pembrolizumab is an immune checkpoint inhibitor targeting the programmed death receptor with clinical effect on multiple malignancies including sarcoma. Associated cardio-toxicities include myocarditis, cardiomyopathy, heart failure, and arrhythmias. Although in most cases of immune checkpoint inhibitor cardiotoxicity the offending agent is discontinued, we report a case of successful and safe re-challenge with a checkpoint inhibitor in a patient with mild myocarditis. Case report: We describe a 37-year-old female with alveolar soft part sarcoma, metastatic to the lungs on cycle 13 of pembrolizumab who presented with dyspnea, cough, and vague chest discomfort. Telemetry showed bigeminal bradycardia that transitioned to self-terminating torsades de pointes. Cardiac MRI showed subtle patchy T2 signal increase within the left ventricular septum without late gadolinium uptake, suggesting mild focal myocarditis.Management and outcome: The patient was started on a steroid taper without additional arrhythmias. We have re-challenged the patient who safely tolerated re-challenge with pembrolizumab despite an episode of torsades de pointes and documented myocarditis. She continues to receive pembrolizumab at seven months after the initial event without further cardiovascular events. Discussion: To the best of our knowledge, this is the first reported case of successful re-challenge of pembrolizumab after an episode of myocarditis. In patients with mild myocarditis and no evidence of left ventricular dysfunction, re-challenge may be a viable option. However, close monitoring for the development of heart failure, cardiomyopathy, or serious arrhythmias is necessary to ensure patient safety.

Abstract	Ovarian microcystic stromal tumor (MST) is characterized by microcysts, solid cellular regions with lobulated growth, and collagenous or fibrous stroma forming hyaline plaques. While several reports have evaluated the unique pathologic and immunohistochemical profile of these tumors, there has been limited description of the radiologic findings of ovarian microcystic stromal tumor in the literature. We present a case of a 66 year old female who presented for evaluation of a new cystic pelvic mass found to have ovarian microcystic stromal tumor. To our knowledge, this is one of the first reports to evaluate the radiologic features associated with this tumor. An enhanced understanding of the correlation between imaging appearance and specific histopathologic findings may aid in the early recognition of this rare neoplasm.
