A case of diplopia masquerading as ptosis: Unveiling a hidden clival chordoma.

IntroductionChordomas are malignant tumours derived from residual notochord tissue. They are characterized by slow growth and local aggressiveness. Visual symptoms commonly arise from the compression of neighbouring structures.Case DescriptionThe authors describe a 77-year-old male patient who presented with ptosis following cataract surgery. The patient described diplopia and limitations in all directions. Computed tomography imaging revealed a soft tissue mass The pathology report showed a diagnosis of chordoma. The lesion was surgically removed. Six months postoperatively, ptosis surgery was performed.ConclusionsThis case underscores the correlation between skull base tumours such as chordomas and ocular manifestations, emphasizing the critical importance of thorough evaluation in patients with ptosis before undergoing surgery.
