“…La inversión de un hemidiafragma puede estar provocada por un neumotórax a tensión, tumor del propio diafragma, masas intratorácicas o derrame pericárdico, pero la causa más habitual es el DP grande de cualquier etiología (20)(21)(22)(23). Es menos frecuente en el lado derecho por el efecto protector del hígado (24), aunque también se han descrito casos de inversión del hemidiafragma derecho (25). Puede originar disnea, generalmente intensa, una masa abdominal palpable, dolor, distensión abdominal y disfagia si es en el lado izquierdo.…”

Pleural effusion (PE) can change the equilibrium between volume of thoracic cavity and volume of intrathoracic structures, and it can disturb the function of respiratory system, heart, and diaphragm. PE alters scanty the pulmonary gas exchange, but it provokes restrictive changes in pulmonary function proportionally to fluid volume, increase thoracic diameters, and decrease lung compliance. PE can originate a syndrome similar to cardiac tamponade. Elevate intrapleural pressure increase intrapericardic pressure and this disturb the cardiac chambers filling, specially right chambers, and decrease cardiac output. Large PE can invert the diaphragm inducing paradoxical movement that origin a reduction of alveolar ventilation. All these alterations improve with drainage of the PE. We think that PE must always be drained, specially if respiratory failure is present.
