Background And Objective: Pancreatic adenocarcinoma remains a dismal disease and is expected to become an even greater burden in the near future. This review focuses on the different surgical aspects for pancreaticoduodenectomy (PD), distal and total pancreatectomy (TP), incorporating lessons from both the western and eastern visions in treating pancreatic cancer.

Methods: We conducted an extensive literature review through PubMed, prioritizing papers published in the last 5 years, but older emblematic papers were also included.

Although vaccination against Coronavirus disease-2019 (COVID-19) is still occurring, several adverse effects temporally related to these vaccines are already being reported, even if through isolated case reports. In the present study, we describe the lesions seen on magnetic resonance imaging (MRI) of three patients who developed neurological symptoms after receiving the ChAdOX1 nCoV-19 vaccine (Oxford/AstraZeneca). The first patient presented with an ischemic stroke in the posterior limb of the left internal capsule, two days after vaccination.

Background: Diffusion tensor imaging has emerged as a promising tool for quantitative analysis of neuronal damage in Parkinson disease, with potential value for diagnostic and prognostic evaluation.

Purpose: The aim of this study was to examine Parkinson disease-associated alterations in specific brain regions revealed by diffusion tensor imaging and how such alterations correlate with clinical variables.

Material And Methods: Diffusion tensor imaging was performed on 42 Parkinson disease patients and 20 healthy controls with a 1.

Detection and staging of prostate cancer (PCa) based on digital rectal examination, prostate-specific antigen levels, and systematic transrectal ultrasound-guided biopsies show notorious limitations in light of the current needs of PCa management. Multiparametric magnetic resonance imaging (mpMRI) has emerged as a useful noninvasive imaging technique for detection, staging, assessment of aggressiveness, and treatment monitoring of PCa, combining anatomic high-resolution T2-weighted images with functional techniques, such as diffusion-weighted imaging and dynamic contrast enhancement evaluation. In this article, the authors review the technical aspects and the current clinical role of mpMRI for detection and locoregional staging of PCa.

Background: Burkitt lymphoma rarely affects the central nervous system and ocular region. Under these conditions, computed tomography and (particularly) magnetic resonance imaging of the skull increase the diagnostic accuracy, as they objectively show the topography of lesions and the effect of neoplasia on structures.

Case Report: We report here the case of a 17-year-old male whose initial clinical manifestations were related to neurological impairment and to the ocular musculature and ocular innervation.
