Primary Hydatid Cyst of Neck Misdiagnosed as Lipoma: A Rare Case Report From Nepal

Hydatid disease, caused by Echinococcus tapeworm infection, presents a significant health concern, particularly in low and middle‐income countries. This zoonotic disease predominantly affects the liver and lungs but can occur in various locations throughout the body. Here, we report a rare case of a 10‐year‐old girl with a hydatid cyst in the nape of her neck. Initially misdiagnosed as a lipoma on clinical examination, ultrasonography revealed the cystic nature of the mass, and histopathological examination done after surgery confirmed the diagnosis. This case highlights the importance of considering hydatid cysts in the differential diagnosis of neck masses among pediatric patients in endemic regions to ensure timely diagnosis and appropriate management.
