Solitary pulmonary hydatid cyst rediologically simulating a giant emphysematous bulla

ABSTRACT

In this case report we present a case of large solitary hydatid disease of the lung which was discovered incidentally. The lesion was similar to bullous emphysema with its thin wall and absence of calcification. CT scan examination was useful especially the CT attenuation number of its internal structure which was nearly one Hounsfield unit [HU] indicating the serous nature of its content as compared to -100 HU which was characteristic of air in emphesematous bullae
