Radiation Necrosis: A Differential Diagnosis Dilemma

Key Points

• The aim is to explore the challenges in differentiating radiation necrosis from disease recurrence following cranial radiation therapy.
• Review of existing literature on radiation necrosis and its mechanisms.
• Analysis of clinical cases presenting similar symptoms to disease recurrence.
• Assessment of imaging techniques for accurate diagnosis.
• Radiation necrosis was often misdiagnosed as disease recurrence due to overlapping symptoms.
• Specific imaging findings helped clarify cases of true radiation necrosis.
• Early recognition of radiation necrosis may prevent unnecessary interventions for presumed disease recurrence.
