title: A left-sided asymptomatic supraclavicular cystic mass in a 14-year-old girl.
abstract: A 14-year-old girl was referred to our department with a 3-month history of an asymptomatic swelling in the left cervical triangle. The girl, an active ski jumper, was used to carrying her skis on the left shoulder. There was a history of many minor falls and contusions of her body. The left posterior cervical triangle was enlarged by an elastic, partially fluctuating and clearly delineated swelling with 4-6 cm in diameter. The trapezius was elevated and the overlaying skin was intact. It was clear that the mass was spreading infraclavicularly. Nevertheless, the distal boundaries of the mass were not quite clear (Fig. 1). The infraclavicular spreading was confirmed with an ultrasound examination which revealed a hypoechogenic echo-free mass of the size of 7-10 x 3.6 cm. The mass was sonocompressible, clearly outlined and there were no signs of any infiltrating growth. No internal perfusion was found by colour-coded Doppler investigation. The blood count or biochemical tests did not reveal any pathological findings.
