Consensus statement on thoracic radiology terminology in Portuguese used in Brazil and in Portugal.

Effective communication among members of medical teams is an important factor for early and appropriate diagnosis. The terminology used in radiology reports appears in this context as an important link between radiologists and other members of the medical team. Therefore, heterogeneity in the use of terms in reports is an important but little discussed issue. This article is the result of an extensive review of nomenclature in thoracic radiology, including for the first time terms used in X-rays, CT, and MRI, conducted by radiologists from Brazil and Portugal. The objective of this review of medical terminology was to create a standardized language for medical professionals and multidisciplinary teams.

ABSTRACT Effective communication among members of medical teams is an important factor for early and appropriate diagnosis. The terminology used in radiology reports appears in this context as an important link between radiologists and other members of the medical team. Therefore, heterogeneity in the use of terms in reports is an important but little discussed issue.

RESUMO A comunicação eficiente entre a equipe médica é um fator importante no diagnóstico e tratamento precoce e adequado dos pacientes. A terminologia utilizada em relatórios de exames radiológicos aparece nesse contexto como um elo importante entre radiologistas e os demais integrantes da equipe médica. Portanto, a heterogeneidade no uso de termos em relatórios é importante mas ainda pouco discutida. Este artigo é resultado de uma extensa revisão da nomenclatura radiológica em radiologia torácica, englobando pela primeira vez termos utilizados em vários métodos (radiografia, TC e RM), desenvolvida por radiologistas brasileiros e portugueses. O objetivo desta revisão da terminologia médica foi criar uma linguagem padronizada para os profissionais médicos e as equipes multidisciplinares.

Clinical diagnosis of patients subjected to surgical lung biopsy with a probable usual interstitial pneumonia pattern on high-resolution computed tomography.

BACKGROUND: Usual interstitial pneumonia can present with a probable pattern on high-resolution computed tomography (HRCT), but the probability of identifying usual interstitial pneumonia by surgical lung biopsy in such cases remains controversial. We aimed to determine the final clinical diagnosis in patients with a probable usual interstitial pneumonia pattern on HRCT who were subjected to surgical lung biopsy. METHODS: HRCT images were assessed and categorized by three radiologists, and tissue slides were evaluated by two pathologists, all of whom were blinded to the clinical findings. The final clinical diagnosis was accomplished via a multidisciplinary discussion. Patients with a single layer of honeycombing located outside of the lower lobes on HRCT were not excluded. RESULTS: A total of 50 patients were evaluated. The most common final clinical diagnosis was fibrotic hypersensitivity pneumonitis (38.0%) followed by idiopathic pulmonary fibrosis (24.0%), interstitial lung disease ascribed to gastroesophageal reflux disease (12.0%) and familial interstitial lung disease (10.0%). In the group without environmental exposure (n = 22), 10 patients had a final clinical diagnosis of idiopathic pulmonary fibrosis (45.5%). Irrespective of the final clinical diagnosis, by multivariate Cox analysis, patients with honeycombing, dyspnoea and fibroblastic foci on surgical lung biopsy had a high risk of death. CONCLUSIONS: The most common disease associated with a probable usual interstitial pneumonia pattern on HRCT is fibrotic hypersensitivity pneumonitis followed by idiopathic pulmonary fibrosis and interstitial lung disease ascribed to gastroesophageal reflux disease. In patients without environmental exposure, the frequencies of usual interstitial pneumonia and a final clinical diagnosis of idiopathic pulmonary fibrosis are not sufficiently high to obviate the indications for surgical lung biopsy.

Squawks in interstitial lung disease prevalence and causes in a cohort of one thousand patients.

Squawks are lung adventitious sounds with a mix of both musical and nonmusical components heard during the inspiratory phase. Small series have described squawks in interstitial lung diseases. Hypersensitivity pneumonitis and other diseases involving small airways can result in squawks, but new interstitial lung diseases (ILDs) involving peripheral airways are being described. A retrospective analysis was performed on 1000 consecutive patients from a database of ILD of a tertiary referral center. Squawks were recorded in 49 cases (4.9%), hypersensitivity pneumonitis (23 cases), connective tissue disease (7), microaspiration (4), pleuroparenchymal fibroelastosis (4), fibrosing cryptogenic organizing pneumonia (, 3), familial ILD (2), sarcoidosis (2), idiopathic pulmonary fibrosis (IPF; 1), bronchiolitis (2), and nonspecific interstitial pneumonia (1). One patient had a final diagnosis of IPF. There was a significant association between mosaic pattern and squawks: 20 cases with squawks (40.8%) had mosaic pattern compared with 140 (14.7%) cases without squawks (x = 23.6, P < .001).Findings indicative of fibrosis were described on high-resolution chest tomography (HRCT) in 715 cases (71.5%). Squawks were more common in patients with findings indicative of fibrosis on HRCT: 45 of 715 (6.3%) compared with 4 of 285 (1.4%) of those without findings indicative of fibrosis (x = 10.46, P = .001).In conclusion, squawks are an uncommon finding on physical examination in patients with ILD, but when present suggest fibrosing ILD associated with bronchiolar involvement. However, squawks are rare in IPF.

Papilomatose laringotraqueobrônquica: aspectos em tomografia computadorizada de tórax / Laryngotracheobronchial papillomatosis: findings on computed tomography scans of the chest

OBJETIVO: Apresentar os achados em tomografia computadorizada (TC) de tórax em pacientes com papilomatose laringotraqueobrônquica. MÉTODOS: Foram estudadas, retrospectivamente, as TCs de oito pacientes, cinco masculinos e três femininos, com idades variando de 5 a 18 anos, com média de 10,5 anos. Os exames foram analisados por dois radiologistas, de forma independente, e as decisões finais foram obtidas por consenso. RESULTADOS: Os achados mais comuns nas TCs foram as lesões nodulares da traquéia e os nódulos pulmonares, muitos com escavação. CONCLUSÕES: O aspecto tomográfico mais freqüentemente observado nos casos de papilomatose laringotraqueobrônquica foi a associação de lesões polipóides de traquéia com múltiplos nódulos pulmonares, vários deles escavados.

OBJECTIVE: To present the findings of computed tomography (CT) scans of the chest in patients with laryngotracheobronchial papillomatosis. METHODS: We retrospectively analyzed CT scans of eight patients, five males and three females, ranging from 5 to 18 years of age with a mean age of 10.5 years. Images were independently reviewed by two radiologists. In discrepant cases, a consensus was reached. RESULTS: The most common CT findings were intratracheal polypoid lesions and pulmonary nodules, many of which were cavitated. CONCLUSIONS: In patients with laryngotracheobronchial papillomatosis, the most common tomographic finding was the combination of intratracheal polypoid lesions and multiple pulmonary nodules, many of which were cavitated.
