Imagem em tuberculose pulmonar

Abstract: A tuberculose é uma doença de alta incidência e prevalência no Brasil. Sinais sugestivos de atividade ou seqüela da tuberculose podem ser obtidos através dos métodos de imagem. Na radiografia de tórax, a tuberculose pulmonar ativa pode manifestar-se sob a forma de consolidações, cavitações, padrões intersticiais (reticulares/retículo-nodulares), linfonodomegalias hilares ou mediastinais e derrame pleural. Imagens compatíveis com doença ativa, como nódulos centrolobulares de distribuição segmentar, cavidades de… Show more

“…In one study, (15) X-rays revealed nodules in only 1.3% of tuberculosis patients co-infected with HIV. In another study, (24) nodules constituted the most common CT finding in patients with active tuberculosis, having been found in 82.0% of the cases. This disparity can be attributed to the difference in sensitivity between the two methods.…”

“…This is in accordance with the literature: in developed countries, tuberculomas account for 14-24% of the cases of resection of suspicious nodules. (10)(11)(12) In practice, high-risk patients and patients with pulmonary nodules presenting enhancement greater than 15 UH are submitted to biopsy or surgical excision of the nodules. (13) Imaging studies showed involvement of all types and in all thoracic compartments, from the airways, with tracheal and bronchial stenosis, to the spinal column, with collapse of the thoracic vertebra, to the lung parenchyma, with nodules and cavitations, and to the pleural cavity, with pleural effusion and thickening.…”

“…Chest radiography is the imaging method of choice in the initial evaluation and follow-up of pulmonary tuberculosis (4) . However, in 6% to 20% of HIV-positive patients with pulmonary tuberculosis conventional radiography may present as absolutely normal (5) .…”

“…High-resolution CT (HRCT) demonstrates small cavities intermingled with consolidations that many times are not visible at conventional radiography (4) . A study developed by Im et al (15) has demonstrated that the prevalence of cavities at tomography was 58% (24/41), while, at plain chest radiography, the prevalence was 22% (9/41).…”
