Traube semilunar space

Pronunciation: trow'be

Definition: a crescentic space about 12-cm wide, bounded medially by the left border of the sternum, above by an oblique line from the sixth costal cartilage to the lower border of the eighth or ninth rib in the midaxillary line and below by the costal margin; the percussion tone here is normally tympanitic, because of the underlying stomach, but is modified by pulmonary emphysema, a pleural effusion, or an enlarged spleen.
