A puzzling paediatric parotid haematoma

Abstract An unusual case of an intra-parotid haematoma is presented. The history was misleading and the ultrasound and CT results apparently contradictory. The investigations are explained in the light of the natural process of haematoma evolution. It is recommended that all radiological investigations be correlated by a single radiologist, and suggested that repeated ultrasound scans, at appropriate time intervals, might be used to confirm the diagnosis and follow the process of clot resolution.
