| Radiographs in chronic OM document deformed bone, often with thick, undulating cortices, and bony sequestra entrapped by lucencies indicative of fibrous tissue and or pus. |
| In cylindrical bronchiectasis, linear, parallel lucencies are sometimes viewed emanating from the hilum. |
| The sub-articular lucencies most probably represent intra-osseous tophi. |
| Radiologically, intraosseous ganglia appear as rounded lucencies in bone with sharp, often sclerotic, borders. |
