Optimization of magnetic resonance imaging protocol for the diagnosis of transient global amnesia
Conclusion: MRI can confirm a clinical hypothesis of transient global amnesia. Knowledge of the optimal diffusion parameters and the ideal timing of diffusion-weighted imaging (> 24 h after symptom onset) are essential to improving diagnostic efficiency.Resumo Objetivo: Enfatizar o protocolo de difus ão mais adequado para detecção de lesões da amnésia global transitória, a fim de realizar um exame preciso, em tempo ideal, após o início dos sintomas. Materiais e Métodos: Foram analisados cinco pacientes com diagnóstico de amnésia global transitória atendidos entre 2012 e 2015, consid erando-se dados demogrÃ...

Progression rate in Bosniak category IIF complex renal cysts
Conclusion: The progression rate in Bosniak category IIF cysts was low. Even lesions that were upgraded on follow-up remained stable, indicating an indolent behavior. Our data support the idea of conservative management of Bosniak IIF renal cyst.Resumo Objetivo: Avaliar a taxa de progress ão das lesões císticas renais complexas Bosniak II-F e a taxa de neoplasia maligna nas lesões ressecadas cirurgicamente. Materiais e Métodos: Realizamos uma pesquisa no banco de dados da nossa instituição reunindo lesões císticas renais complexas classificadas como Bosniak II-F em exames d e tomografia computadorizada ou resson...

Elastography for the evaluation of thyroid nodules in pediatric patients
Conclusion: Our results suggest that high elasticity of a nodule on elastography is associated with a low risk of thyroid cancer. If further confirmed in other studies, elastography may prove useful as a complementary test for screening thyroid nodules in children.Resumo Objetivo: Avaliar a utilidade da elastografia (usando compress ão manual) como uma ferramenta adicional de diagnóstico em crianças e adolescentes com nódulos da tireoide. Materiais e Métodos: Este foi um estudo prospectivo realizado entre setembro de 2012 e agosto de 2013 em um hospital no Brasil. Realizamos elastografia, ultrassonografia e biópsia...

Subpubic cartilaginous cyst: a rare cause of vulvar lesion
Abstract Acute penile conditions, which typically have a traumatic, vascular, or infectious etiology, are rather uncommon and often require prompt medical evaluation. Penile emergencies can be treated conservatively or surgically, and their management often relies on the results of imaging examinations. Because of its high spatial resolution and wide availability, as well as the fact that it does not involve the use of ionizing radiation, ultrasound is the imaging modality of choice in the initial evaluation of penile emergencies. Inconclusive cases can be further evaluated with magnetic resonance imaging. The main purpose...
