Introduction: Lesion localization based on patient’s manifestation is a fundamental step in making a neurological diagnosis. However, it has been reported that diagnosticians are vulnerable to the effects of various cognitive biases during diagnostic processes. Case Report: A 69-year-old man with right-hand stiffness visited the Movement Disorder Clinic with the history of periodic limb movement syndrome and restless leg syndrome. His sensory and deep tendon reflex examination results were normal. Brain magnetic resonance imaging was normal. Corticobasal degeneration was considered as a possibility, but functional imaging studies including FP-CIT positron emission tomography were all normal. Later, cervical spine magnetic resonance imaging revealed a cervical meningioma at the C2-C3 levels and he showed tingling senses in his right ulnar 3 fingers and a hyperactive knee jerk on his right side, which were absent on the first examinations. Conclusions: Insufficient clinical information (declarative shortcoming) and inherent heuristic pitfalls (procedural shortcoming) were 2 major causes of the diagnostic error. Especially, in the present case, cognitive biases from framing effects and anchoring heuristics misled the clinical reasoning during the process of localization.
