Terson syndrome in a patient with CML with central nervous system involvement
C. Magnetic resonance imaging of the brain and orbits
This patient, who had refractory CML and blurry vision, presented with bilateral peripapillary hemorrhages and whitening suggestive of possible optic nerve edema. His presentation was concerning for leukemic optic nerve infiltration. Also considered were hypertensive papillopathy, an intracranial mass with intracranial hypertension, an intracranial hemorrhage with Terson syndrome, and inflammatory or infectious sources of bilateral atypical optic neuritis. Urgent magnetic resonance imaging of the brain and orbits was ordered (choice C), and high-dose intravenous methylprednisolone was started. Magnetic resonance imaging revealed subdural and subarachnoid hemorrhage without optic nerve enlargement or enhancement, findings that did not suggest leukemic optic nerve infiltration.1 A lumbar puncture demonstrated red blood cells, a mildly elevated opening pressure of 31 cm H2O, and cytology findings of malignant cells consistent with CML with central nervous system (CNS) involvement. Given the intracranial hemorrhage with both intraretinal and preretinal hemorrhages, a diagnosis of Terson syndrome was made.
