Introduction: Left ventricular non-compaction (LVNC) is characterized by extensively trabeculaed myocardium adjacent to normal compacted myocardium of the left ventricle (LV). Hypertrophic cardiomyopathy (HCM) typically appears as diffuse or segmental LV hypertrophy, with or without outflow tract obstruction. Cardiac sarcomere mutations are present in most HCM cases and have also been identified in LVNC. Whether or not there is clinically significant phenotypic overlap between the two diseases is less well understood. We present a case of known HCM that met criteria for both LVNC and HCM by cardiac MRI. Case: A 49-year old man with HCM due to a c.3742_3759dup variant in MYBPC3 presented to clinic after an episode of syncope and ICD firing. In clinic, the device was interrogated and he was found to have had ventricular flutter which was successfully treated with one shock and a new, high (>20%) burden of premature ventricular beats. An echocardiogram showed a stable ejection fraction at 42%, mild concentric LV hypertrophy without obstruction and a newly dilated LV with an end diastolic diameter of 7.1cm (previously 6.2cm). A cardiac MRI was performed ( Figure ) and showed LV noncompaction and diffuse transmural and mid myocardial hyperenhancement/fibrosis of the septum, basilar lateral wall, anterior wall, and distal right ventricle consistent with patient's long-standing history of hypertrophic cardiomyopathy. Discussion: This case highlights the phenotypic overlap between HCM and LVNC by cardiac MRI. Had this patient not already carried a genetic diagnosis of HCM, he would likely have been diagnosed with LVNC based on this cardiac MRI. The phenotypic overlap in these diseases raises questions about ICD guidelines, the role of anticoagulation and prognosis.

Hypertrophic cardiomyopathy (HCM) is a global disease affecting people of various ethnic origins and both genders. HCM is a genetic disorder with a wide range of symptoms, including the catastrophic presentation of sudden cardiac death. Proper diagnosis and treatment of this disorder can relieve symptoms and prolong life. Non-invasive imaging is essential in diagnosing HCM. We present a review to deliberate the potential use of cardiac magnetic resonance (CMR) imaging in HCM assessment and also identify the risk factors entailed with risk stratification of HCM based on Magnetic Resonance Imaging (MRI).

AbstractIn this paper, the structural and functional imaging changes associated with sporadic and genetic Parkinson’s disease and atypical Parkinsonian variants are reviewed. The role of imaging for supporting diagnosis and detecting subclinical disease is discussed, and the potential use and drawbacks of using imaging biomarkers for monitoring disease progression is debated. Imaging changes associated with nonmotor complications of PD are presented. The similarities and differences in imaging findings in Lewy body dementia, Parkinson’s disease dementia, and Alzheimer’s disease are discussed.

Owing to the rarity and the biological and clinical heterogeneity of gastroenteropancreatic neuroendocrine neoplasia (GEP NEN), the management of these patients may be challenging for physicians. This review highlights the specific features of GEP NEN with particular attention on the role of Ki67 heterogeneity, the potential prognostic role of novel radiological techniques, and the clinical usefulness of functional imaging, including 68Ga-DOTA-SST PET/CT and 18F-FDG PET/CT. Understanding these specific features may help to plan proper and tailored follow-up programs and therapeutic approaches.

AbstractIn this work, we sought to delineate the prevalence of cardiothoracic imaging findings of Proteus syndrome in a large cohort at our institution. Of 53 individuals with a confirmed diagnosis of Proteus syndrome at our institution from 10/2001 to 10/2019, 38 individuals (men, n = 23; average age = 24 years) underwent cardiothoracic imaging (routine chest CT, CT pulmonary angiography and/or cardiac MRI). All studies were retrospectively and independently reviewed by two fellowship-trained cardiothoracic readers. Disagreements were resolved by consensus. Differences between variables were analyzed via parametric and nonparametric tests based on the normality of the distribution. The cardiothoracic findings of Proteus syndrome were diverse, but several were much more common and included: scoliosis from bony overgrowth (94%), pulmonary venous dilation (62%), band-like areas of lung scarring (56%), and hyperlucent lung parenchyma (50%). In addition, of 20 individuals who underwent cardiac MRI, 9/20 (45%) had intramyocardial fat, mostly involving the endocardial surface of the left ventricular septal wall. There was no statistically significant difference among the functional cardiac parameters between individuals with and without intramyocardial fat. Only one individual with intramyocardial fat had mildly decreased function (LVEF = 53%), while all others had normal ejection fraction.
