Supraclavicular Hydatid Cyst: An Unusual Cause of Neck Swelling

Hydatid disease, also known as echinococcosis or hydatidosis, is a zoonotic infection caused by the larval forms (metacestode) of Echinococcus granulosus. Hydatid disease is an important public health problem and is endemic in sheep and cattle raising areas worldwide. Musculoskeletal or soft tissue hydatidosis accounts for about 0.5%-5%. Even in regions where echinococcosis is endemic, hydatidosis of cervicofacial region is extremely rare. We present an unusual case of a hydatid cyst in 60 years old male who presented as supraclavicular swelling for a duration of 1 and half years. The swelling was slow on growth and there was vague pain for the last 8 months duration.
