Imaging Findings after Multidisciplinary Treatment for Orbital and Ocular Adnexal Cancers

Various modalities, including computed tomography (CT), MR imaging, and PET/CT, are used in the radiological assessment of the treated orbit. Understanding the different surgical procedures used for orbital and ocular adnexal tumors and the imaging characteristics of recurrent tumors after complex reconstructive procedures in the orbital region is critical. Knowledge of treatment complications, including infection, osteoradionecrosis, radiation necrosis, radiation-associated secondary sarcomas, and tumor recurrence, is also important. To assist the radiologist, this article highlights several common orbital surgical procedures and complications that may arise following treatment.
