ABSTRACT
Objective To demonstrate the X-ray and CT features of breast hydatid disease.Methods Of 11 patients with pathologically confirmed breast Echinococcus hydatid disease were collected and the X-ray and CT image data were analyzed.Results Of 11 patients with hydatid cysts,single cyst was found in 9 patients which one cyst was ruptured due to trauma,multiple cyst in 2 patients.Mammography showed small or large shadow in different size,with low or high density and smooth margin.Calcification was found in 5 and 2 patients with egg shell-like calcification along the wall of cyst,3 patients with spotted calcification within cyst.One case had cavity-like change (annular solar eclipse sign).Cystic lesion with a complete capsule was demonstrated on CT scan in 1 patient.Conclusion Molybdenum target mammography can accurately display the imaging characteristics of hydatid cyst and improve the diagnostic ability of breast hydatid cyst in combination with clinical and epidemiological data.
