Differential diagnosis of thrombosis and myxoma in unusual heart positions by dual-energy CT multiple parameter imaging: A case series.
Medicine (Baltimore)

Department of Medical Imaging, Jincheng People's Hospital, Shanxi, China.
Rationale: Thrombus is the most common occupying lesion in the cardiac chambers, it is often distinguished from cardiac neoplastic occupations. Among them, the most common is cardiac myxoma, whose imaging manifestations are often confused with thrombus. However, the 2 types of lesions have different therapeutic strategies and are both potentially high-risk sources of embolism, so early differentiation between intracardiac thrombus and cardiac tumor is essential.

From the Department of Nuclear Medicine, Central People's Hospital of Zhanjiang, Zhanjiang, China.
Subcutaneous nodules and masses as the primary manifestation of diffuse large B-cell lymphoma are exceedingly rare. We present 18F-FDG PET/CT findings of multiple hypermetabolic nodules and masses distributed throughout the body, creating a characteristic "leopard man" appearance on the MIP image, in a 65-year-old man. An excisional biopsy of the right thigh mass confirmed the diagnosis of diffuse large B-cell lymphoma.

Department of Neurology, Isfahan University of Medical Sciences, Isfahan, Iran.
Background: Multiple sclerosis (MS) is an autoimmune disorder affecting the central nervous system, with varying clinical manifestations such as optic neuritis, sensory disturbances, and brainstem syndromes. Disease progression is monitored through methods like MRI scans, disability scales, and optical coherence tomography (OCT), which can detect retinal thinning, even in the absence of optic neuritis. MS progression involves neurodegeneration, particularly trans-synaptic degeneration, which extends beyond the initial injury site.

Rio de Janeiro State University, Rio de Janeiro, Brazil.
Aim: Assess the prevalence and severity of molar incisor hypomineralization (MIH) in children 6- to 12-year-old and correlate MIH severity with the complexity of treatment demands.
Materials And Methods: Between March and October 2023, 2,136 children were screened for MIH by two calibrated examiners. MIH severity was categorized in mild, moderate, severe, and very severe.
Central nervous system involvement in Waldenström macroglobulinemia: a comparative population-based study of Bing-Neel syndrome and histological transformation.

Department of Pathology, Copenhagen University Hospital - Zealand University Hospital Roskilde, Roskilde, Denmark.
Central nervous system (CNS) involvement in Waldenström macroglobulinemia (WM) is a rare complication that can manifest as Bing-Neel syndrome (BNS) or as histological transformation (HT) to diffuse large B-cell lymphoma (DLBCL). We report data from a single-center cohort of 469 patients consecutively diagnosed with WM between 2000 and 2022. BNS was identified in 1.
