ABSTRACT
Introducción No se ha determinado la evolución de los pacientes con derrames pleurales idiopáticos con un seguimiento a largo plazo. Métodos Entre octubre de 2013 y junio de 2021 se hizo un seguimiento prospectivo de todos los pacientes con derrame idiopático mediante exploración clínica y estudios de imagen al cabo de 1, 3 y seis meses y cada seis meses durante un mínimo de un año. Resultados Veintinueve pacientes fueron diagnosticados de derrame idiopático y objeto de seguimiento. Durante el seguimiento se detectó un mesotelioma en dos pacientes al cabo de siete y 18 meses; en uno de ellos se observó líquido pleural teñido de sangre y el otro refirió una pérdida de peso de 10%. En ninguno de los pacientes con derrame que cubriera menos de dos tercios del hemitórax y sin síntomas constitucionales ni aparición de líquido teñido de sangre se diagnosticó un mesotelioma. La mayoría de los derrames desaparecieron o mostraron una clara mejoría en los primeros seis meses. Conclusiones Los pacientes sin pérdida de peso y con derrames no hemáticos pequeños pueden beneficiarse de un tratamiento conservador y un seguimiento clínico-radiológico (AU)
Introduction Long-term follow-up course for patients with idiopathic pleural effusions has not been established. Methods From October 2013 to June 2021 all patients with idiopathic effusion were prospectively followed up with clinical examination and imaging at 1,3,6 and every 6 months for a minimum of 1 year. Results Twenty-nine patients were diagnosed with idiopathic effusion and followed up. Mesothelioma was detected during the follow-up in two patients at 7 and 18 months, one of whom had blood-tinged pleural fluid and the other reported a 10% weight loss. Mesothelioma was not diagnosed in any of the patients with effusion covering less than two thirds of the hemithorax, and without constitutional symptoms or a blood-tinged fluid appearance. Most of the effusions resolved or showed a clear improvement in the first six months. Conclusions Patients without weight loss and with small, non-hematic effusions, may benefit from conservative treatment and clinical-radiological follow-up (AU)

INTRODUCTION: Long-term follow-up course for patients with idiopathic pleural effusions has not been established. METHODS: From October 2013 to June 2021 all patients with idiopathic effusion were prospectively followed up with clinical examination and imaging at 1, 3, 6 and every 6 months for a minimum of 1â¯year. RESULTS: Twenty-nine patients were diagnosed with idiopathic effusion and followed up. Mesothelioma was detected during the follow-up in two patients at 7 and 18 months, one of whom had blood-tinged pleural fluid and the other reported a 10% weight loss. Mesothelioma was not diagnosed in any of the patients with effusion covering less than two thirds of the hemithorax, and without constitutional symptoms or a blood-tinged fluid appearance. Most of the effusions resolved or showed a clear improvement in the first six months. CONCLUSION: Patients without weight loss and with small, non-hematic effusions, may benefit from conservative treatment and clinical-radiological follow-up.
