Abstract:
Purpose:A case of optic tract injury caused by subarachnoid hemorrhage in the perimesencephalic cistern is reported.Case summary: A 26-year-old female with a history of traumatic subdural hemorrhage along the bilateral frontal convexity presented with a right visual field defect. Her visual acuity was 1.0 in both eyes. Slit-lamp examination and fundus examination were not remarkable. There was a relative afferent pupillary defect in the right eye. A Humphrey visual field test revealed right homonymous hemianopsia. Optical coherence tomography showed left homonymous hemiatrophy of the ganglion cell-inner plexiform layer in both eyes. Magnetic resonance imaging was performed. Susceptibility-weighted images showed minimal subarachnoid hemorrhage in the left perimesencephalic cistern, and the patient was confirmed to have optic tract injury due to subarachnoid hemorrhage.
Conclusions:We report a case of optic tract injury in a 26-year-old patient caused by subarachnoid hemorrhage in the perimesencephalic cistern, which was confirmed by susceptibility-weighted images.
