Diagnosis in imaging is rarely as straightforward as textbooks suggest. In real clinical practice, radiologists integrate subtle imaging clues with clinical findings to construct a differential diagnosis and progressively narrow it toward a final conclusion. Despite this systematic approach, certain entities remain easily confused.

This session focuses on diseases in the head and neck region that are frequently misinterpreted on imaging and explores practical strategies for differential diagnosis. Rather than a one-way lecture, the session is designed as an interactive experience in which participants actively engage through real-time voting and discussion, collectively building and refining differential diagnoses.

Among the many potentially confusing conditions, particular emphasis will be placed on distinguishing inflammatory diseases from malignant tumors, as well as differentiating among various benign tumors. Through shared reasoning and case-based discussion, participants will practice the interpretive process that underlies accurate radiologic diagnosis in complex, real-world settings.
