Primary Giant Echinococcosis of the Neck.

The authors report an isolated echinococcosis in a 17-year-old girl presented with swelling of right neck approximately 12 cm in diameters with no evidence of the disease elsewhere in the body. A thorough search of the literature revealed only a few cases of isolated cervical echinococcosis. Surgical procedure was planned for our case with the guidance of the magnetic resonance imaging, which showed right cystic mass and within a laminar membrane. Histopathologic report confirmed echinococcosis. In summary, this current study shows that in the differential diagnosis of the cystic masses localized in the neck in the endemic regions, echinococcosis should be suggested. In these patients, the careful assessment of the magnetic resonance imaging evaluation before the surgery would extremely facilitate either the diagnosis or the surgery planning.
