RESUMO
Two cases are presented which illustrate the radiological drawbacks and advantages of air when it is present either around or within an organ of clinical interest. The physical principles underlying this anomaly are briefly discussed, particularly in relation to plain film radiology and ultrasonic imaging. The importance of recognising this phenomenon and the diagnostic difficulties which may arise are stressed (AU)

Pre-operative diagnosis of segmental infarction of the omentum is difficult because of its rarity and non-specific clinical features. We present a case of omental infarction and suggest that ultrasound scan may be helpful in the diagnosis of this entity (Summary)
