Pulmonary aspiration chest x ray

The location of abscesses caused by aspiration depends on the position one is in. If one is sitting or standing up, the aspirate ends up in the posterior basal segment of the right lower lobe. If one is on one’s back, it goes to the superior segment of the right lower lobe. If one is lying on the right side, it goes to the superior segment of the right middle lobe, or the posterior basal segment of the right upper lobe. If one is lying on the left, it goes to the lingula.
