Abstract
Chickenpox is considered as a mild disease, but sometimes it is associated with complications. Among them sialadenitis is mentioned sporadically. We describe a case of the 6-year-old girl suffering from complicated chickenpox. On the basis of clinical data and ultrasound image we diagnosed in her inflammation of both submandibular glands. Moreover, the ultrasound image suggested possibility of an inflammation developing in the left parotid gland.
