Case of August 2011

Clinical History:

An 11 years old girl presented with recurrent swelling at right parotid region for a few months (about 7 episodes in 6 months). The size of swelling fluctuated throughout each episode, but never returns to normal during the quiescent periods. Her oral hygiene was satisfactory and there was no history of dental caries or extraction. The episodes were not associated with febrile illness. Initial ultrasound examination of the parotid gland showed no focal mass, stone or dilated ductules. Contrast CT scan of the face was eventually arranged for the provisional clinical diagnosis of recurrent parotitis. X-rays were taken after the CT examination.
