Аннотация
BACKGROUND: Dorsal midbrain syndrome is a triad of signs consisting of vertical gaze palsy, light-near dissociation of the pupils, and convergence retraction nystagmus. Associated findings may also be present. The most-common etiologies are pineal gland tumors and midbrain infarction. Pineal gland tumors are rare tumors that show a predilection for males. The specific tumor reported herein, a pineocytoma, shows no gender predilection and is most common in mid- to late adulthood.
CASE REPORT: A 38-year-old Native American man came to us with signs and symptoms consistent with dorsal midbrain syndrome. A neurological evaluation revealed the presence of a pineocytoma, which was later excised unsuccessfully. An explanation of the findings associated with dorsal midbrain syndrome is provided.
CONCLUSION: Patients who demonstrate signs consistent with dorsal midbrain syndrome should be referred for a neurological evaluation--including an MRI--to rule out any midbrain lesion.
