ABSTRACT
The high number of knee imaging exams at radiology clinics, together with the wide variety of knee disorders, calls for expanding the knowledge about the less common lesions seen in routine diagnostic practice. The purpose of this pictorial essay was to illustrate unusual lesions that distend the knee joint, selected by relevance and evaluated with multiple imaging modalities, including X-ray, computed tomography, and magnetic resonance imaging, as well as to perform a brief review of the literature.
A elevada demanda de exames para avaliação do joelho nos serviços de diagnóstico, bem como a extensa variedade de lesões geniculares, estimulam a ampliação do conhecimento sobre alterações menos frequentes na rotina de diagnósticos. O objetivo deste ensaio iconográfico é ilustrar didaticamente lesões não usuais do joelho com efeito expansivo, escolhidas em razão da relevância clínica e avaliadas por meio de diversos métodos de imagem como radiografia simples, tomografia computadorizada e ressonância magnética, bem como fazer uma breve revisão da literatura.
ABSTRACT
The study describes the main chest radiographic changes in people living with HIV/AIDS and pulmonary tuberculosis, confirmed by sputum culture. This was a descriptive study involving a total of 42 sputum tests from 42 people living with HIV/AIDS and a clinical suspicion of pulmonary tuberculosis. All patients attended two referral hospitals in Recife-PE, Brazil, between August 2009 and January 2012. The most common isolated radiological change was parenchymal consolidation, encountered in six (14.3%) patients, followed by patterns of interstitial infiltrate, diffuse micronodular (miliary), and an association between interstitial infiltrate and parenchymal consolidation, each being encountered in five (11.9%) patients. No statistically significant difference was observed between the radiological findings and CD4 T-cell counts, p = 0.680.
