Quiste Hidatídico en Tibia que Mimetiza Condrosarcoma en el Estudio PET/CT con ¹⁸F-FDG

A hydatid cyst is a zoonotic infection caused by Echinococcus granulosus. The liver and lungs are the most affected organs. Although rare, osseous involvement by hydatid cyst disease can occur because the rigid bone trabeculae prevent formation of the characteristic adventitia. While fluorodeoxyglucose (FDG) positron emission tomography (PET) findings in hepatic and pulmonary hydatid cysts are well described, this case, to the best of our knowledge, represents the first report of bone hydatid disease located in an extremity evaluated by ¹⁸F-FDG PET/computed tomography.
