Supplementary Material for: Gasperini Syndrome: A Rare Brainstem Syndrome, A Case Report

Introduction: This unique case demonstrates how subtle ocular motor abnormalities, even in the absence of visual complaints, can lead to the detection of an otherwise clinically silent brainstem lesion.
Case Presentation: We report on the incidental discovery of a brain tumor following a traffic accident. Despite the absence of ocular symptoms, abnormal oculomotor findings led to further diagnostic investigations and rapid diagnosis of a pontine lesion consistent with Gasparini syndrome.
Conclusion: Our case report highlights the crucial importance of meticulous history-taking, precise neuro-ophthalmological examination, particularly the assessment of ocular motility and interdisciplinary management in patients with complex brainstem syndromes.
