Correlation of ultrasound B-lines with high-resolution computed tomography in antisynthetase syndrome.

OBJECTIVES: Interstitial lung disease is a common finding in patients with the antisynthetase syndrome. High-resolution computed tomography is the reference test for diagnosis and follow-up of this condition, but it involves considerable radiation exposure. Our aim was to describe chest ultrasound features and its correlation with high-resolution computed tomography findings in a series of patients with the antisynthetase syndrome. METHODS: The study included patients from our antisynthetase syndrome cohort with varying degrees of interstitial lung disease, consulting in our outpatient clinic over a 1-year period. Chest high-resolution computed tomography and chest sonography were prospectively performed within a 1-week period. High-resolution computed tomography Warrick score was calculated and chest sonography findings (B-lines) at several sonographic points along the anterior and posterior intercostal spaces were semi-quantitatively analyzed. Rho Spearman statistics were applied for possible correlations. RESULTS: Twenty-one consecutive patients were studied. A median of 59 thoracic points was studied per patient (IQR 6); 44.1% (95% CI 29.9-60.7) of them showed at least one B-line. A correlation coefficient of 0.135 (p=0.5) was found between the percentage of ultrasound points with B-lines and the Warrick's score. Only the number of bronchopulmonary segments showing ground glass findings was associated with the percentage of sonographic points with B-lines (Rho=0.5, p=0.02). CONCLUSIONS: A good correlation between the percentage of sonographic points with B-lines and high-resolution computed tomography ground glass opacities was observed in patients with the antisynthetase syndrome.

Patología vascular torácica en pacientes oncológicos / Thoracic vascular disease in oncologic patients

La patología oncológica requiere frecuentes controles mediante pruebas de imagen, de forma predominante con tomografía computarizada (TC). En estos pacientes podemos encontrar patología vascular torácica que puede influir en el diagnóstico, el tratamiento y el pronóstico de su enfermedad neoplásica. Los tumores primarios vasculares pueden afectar a los vasos torácicos, como las arterias pulmonares (sarcoma de arteria pulmonar), y la enfermedad neoplásica se puede extender localmente (neoplasia pulmonar) o a distancia hacia los vasos torácicos (embolia pulmonar tumoral y microangiopatía trombótica tumoral pulmonar). El tratamiento oncológico es la causa de múltiples complicaciones sobre los vasos torácicos que en determinados casos llegan a comprometer la vida del paciente. La TC, especialmente con técnica multicorte, permite la evaluación de la enfermedad neoplásica y la patología vascular torácica asociada en el paciente oncológico (AU)

Patients with oncologic disease require frequent imaging tests (predominantly computed tomography) for follow-up. These patients may have thoracic vascular disease that can influence the diagnosis, treatment, and prognosis of their cancer. Primary vascular tumors can involve the thoracic vessels, like the pulmonary arteries (pulmonary artery sarcoma), and the neoplastic disease can extend locally (lung tumor) or remotely to the thoracic vessels (pulmonary tumor embolism and pulmonary tumor thrombotic microangiopathy). Oncologic treatment results in multiple complications that involve the thoracic vessels and can even compromise the patient's life in certain cases. CT, and especially multislice CT, makes it possible to evaluate neoplastic disease and associated thoracic vascular disease in oncologic patients (AU)
