The purpose of this exhibit is: 1. To review imaging findings of various spectrum of treatment-related lesions of the brain. 2. To demonstrate the role of current imaging modalities such as MRI and PET-CT in assessing such treatment-related disorders. 3. To highlight the practical imaging assessment, in particular, for the differentiation between post-treatment change from tumor recurrence.  

This exhibit includes various spectrums of treatment-related disorders. 1. Radiation or chemotherapy to the brain induced disorders such as radiation necrosis, pseudoprogression, secondary tumor, chronic expanding hematoma or cystic formation, and radiation-induced vascular lesion. 2. Operation or intervention related disorders such as hyperperfusion and sinus thrombosis. 3. Treatment to other organs or systemic therapy related disorders such as central pontine myelinolysis, posterior reversible encephalopathy syndrome, and drug-induced leukoencephalopathy. We are presenting: 1. Summary of those clinical symptoms, etiology and outcome 2. Characteristic findings of diagnostic imaging and key points for practical imaging assessments and follow up.
