Popis: We report a case of occipital lobe epilepsy (OLE) in a patient with occipital lobe stroke whose diagnosis was complicated by homonymous hemianopsia. An 81-year-old woman presented with a complaint of “blurred vision” on the right side and was kept under outpatient observation at the Hirabayashi Eye Clinic for homonymous lower right hemianopsia, glaucoma, and post-cataract surgery. Her past medical history included hypertension, angina pectoris, atrial fibrillation, diabetes mellitus, and left occipital lobe cerebral infarction. The corrected visual acuity and intraocular pressure were 20/16 and 12 mm Hg and 20/20 and 13 mm Hg in the right and left eye, respectively, and no change was observed in the fundus and visual field defect; hence, the patient was placed under observation. Two days later, the patient voluntarily visited a neurosurgical hospital and underwent magnetic resonance imaging. No abnormalities were detected other than the left obsolete occipital lobe stroke. Five days later, she returned to our clinic because she felt “something wobbly” on her right side. Upon examination, we suspected a transient ischemic attack based on the wobbling, closed eyelids, and loss of consciousness, and referred her to the same neurosurgical hospital. Electroencephalography (EEG) revealed spikes and waves with occipital lobe predominance, and the diagnosis of OLE was made. The patient had right-sided homonymous hemianopsia owing to left occipital lobe cerebral infarction and “blurred vision” on the same side. Thus, it is inferred that EEG is imperative for ruling out epileptic seizures.
