Pueden encontrarse lesiones aisladas o múltiples, formando parte de un trastorno genético llamado exostosis cartilaginosa múltiple hereditaria. El hemotórax espontáneo es una presentación inusual de las exostosis costales. Se describe el caso de un adolescente de 13 años de edad con hemotórax espontáneo secundario a exostosis costal demostrada por técnicas de imagen. Se realizó tratamiento quirúrgico mediante toracoscopia y toracotomía con resección de la lesión.]]></p></abstract>
