Is there something new regarding triceps brachii muscle insertion?

Acta cir. bras; 35 (10), 2020
Abstract Purpose: Previous studies have questioned whether the triceps brachii muscle tendon (TBMT) has a double or single insertion on the ulna. Aiming to provide an answer, we describe the anatomy of the TBMT and review a magnetic resonance imaging (MRI) series of the elbow. Methods: Forty-one elbows...

Adenoma hipofisario ectópico del seno esfenoidal persistente tras cirugía manejado con tratamiento conservador

Los adenomas hipofisarios ectópicos (EPA) constituyen un reto diagnóstico, dada su escasa prevalencia y variada presentación en la que puede incluirse un síndrome de hipersecreción de hormonas hipofisarias. La clínica suele ser larvada e inespecífica, no presentan ninguna característica radiológ...

Bullosis diabeticorum – una lesión poco común

IINTRODUCCIÓN: el bullosis diabeticorum forma parte del espectro de manifestaciones cutáneas de la diabetes mellitus, descrito por Kramer en 1930 y nombrado como bullosis diabeticorum por Cantwell y Martz. Es una enfermedad conocida, pero bastante rara (0.5 a 2% de la población diabética) siendo dos ...

The value of morphofunctional magnetic resonance imaging with hepatospecific contrast agent in the characterization of hepatocellular carcinoma in a non-cirrhotic patient with hepatitis C

SUMMARY Hepatocellular carcinoma in patients with hepatitis C in the absence of cirrhosis is uncommon. We demonstrate the importance of morphofunctional magnetic resonance imaging (MRI) with a hepatospecific contrast agent by describing an asymptomatic female patient with HCV, who presented with a nodule...

The central vein sign in multiple sclerosis: a biomarker evaluated on a 3T MRI scanner

Clin. biomed. res; 40 (2), 2020
The central vein sign (CVS) is a promising MRI biomarker in multiple sclerosis (MS). CVS has recently been proposed to improve the accuracy and speed of MS diagnosis. Evidence indicates that the presence of CVS in individual lesions can accurately differentiate MS from other diseases that mimic this cond...

Evaluation of the frequency of neuroimaging findings in congenital infection by Zika virus and differences between computed tomography and magnetic resonance imaging in the detection of alterations

Abstract INTRODUCTION: Congenital infection by the Zika virus (ZIKV) is responsible for severe abnormalities in the development of the central nervous system. The aim of this study was to evaluate and compare the ability of computed tomography (CT) and magnetic resonance (MR) to detect patterns of invo...

Ischemic stroke related to HIV and SARS-COV-2 co-infection: a case report

Abstract A 56-year-old male with human immunodeficiency virus required hospitalization due to the onset of both dyspnea and asthenia. A computed tomography of the chest exam showed the radiological pattern of coronavirus SARS-CoV-2 pulmonary involvement. Based on immunochromatographic analysis, the patie...

Papel de distintas técnicas de imagen para identificar y localizar cuerpos extraños intraoculares relacionados con trauma ocular abierto: reporte de tres casos y revisión de la literatura

Medwave; 20 (1), 2020
ANTECEDENTES La ubicación precisa de un cuerpo extraño intraocular es crucial para el manejo de pacientes con trauma ocular abierto. La tomografía computarizada se usa habitualmente para detectar su ubicación en el segmento posterior. Reportamos tres casos con diferentes cuerpos extraños intraocular...

Differences in total brain volume between sexes in a cognitively unimpaired elderly population

Clinics; 75 (), 2020
OBJECTIVES: Although a large number of studies have shown brain volumetric differences between men and women, only a few investigations have analyzed brain tissue volumes in representative samples of the general elderly population. We investigated differences in gray matter (GM) volumes, white matter (WM...

Endothelial progenitor cells in the peripheral blood of patients with moyamoya disease labeled with superparamagnetic iron oxide in vitro for MRI detection

Braz. j. med. biol. res; 53 (11), 2020
Moyamoya disease (MMD) is currently thought to involve endothelial progenitor cells (EPCs). We investigated whether superparamagnetic iron oxide (SPIO) can be used to label EPCs. Mononuclear cells from 10 moyamoya disease patients were isolated, and cluster of differentiation 133 (CD133) positive cells s...
