Unusual Presentation of Hydatidosis - Neck Lump Causing Costo-Vertebral Erosion

Abstract

<strong><em>Introduction:</em></strong> <br/>Hydatid disease caused by larval stage of Echinococcus has been recognized endemically in many countries. Liver and lungs are the most commonly affected organs. Involvement of the head and neck region is rare and bony erosion due to hydatidosis is even rarer. <br/> <strong><em>Case Report:</em> </strong> <br/>We report a case of a 17-year-old girl from a poor socio-economic background who presented with a right sided supraclavicular lump, which after surgical excision and histopathological examination was diagnosed as hydatid cyst of neck. <br/> <strong><em>Conclusion:</em> </strong> <br/>Because of its rarity in the neck region, primary diagnosis of hydatid cyst is overlooked and usually not included in the differential diagnosis of cystic neck swellings. A high index of suspicion is necessary to diagnose hydatid disease in an unusual location even in endemic areas.
