What looks really large on ultrasound may in fact be quite small. This is especially true with pleural effusion that looks like a lot on ultrasound but the maximum dimension is only 2 cm (or less than an inch), and merely a fissure line on the thoracic radiograph (TXR) or is missed altogether by TXR. As for masses, the seemingly large splenic mass that deforms the spleen, a serious finding, is really only 3 × 3 × 3 cm (or approximately 1¼ × 1¼ × 1¼ inches), easily missed by palpation during your physical exam and on abdominal radiography; and the lung lesion that appears so obvious is in fact a mere few millimeters (<1/3 inch) being missed or occult by thoracic radiography (and possibly CT) (Figure 5.14). Don't get me wrong, these findings may have a significant clinical bearing on your case, but a small pocket of pleural effusion in a stable case requires a calm and collected mind for decision making, and not overresponding.
