The degree and nature of soft tissue swelling, whether intra‐capsular, extra‐capsular, focal or diffuse, with accompanying effacement of facial planes or fat pads, can help focus on a region of interest. For example, radiographs of a transverse stress fracture of the distal third metacarpal bone may initially reveal no osseous disruption and show only a subtle adjacent soft tissue swelling. Over ensuing weeks, the radiographs can progress dramatically (Chapter 22). Following a skull fracture, haemorrhage in the guttural pouches can obliterate the normal gas lucency which is replaced by soft tissue opacity or produce a fluid line secondary to a gas–fluid interface. Accompanying features of ventral deviation of the dorsal pharyngeal wall and dorsoventral attenuation of the nasopharynx may also be visible.
