Reversible Parinaud's syndrome during the first 24 hours following a transient ischemic attack - A case report and review of literature

Among three types of stroke, ischemic and hemorrhagic types are well-known causes of Parinaud's syndrome while transient ischemic attack (TIA) is not. We present a case of a 45-year-old man, who presented with neurological features of Parinaud's syndrome due to TIA. Our first impression was either a stroke or a compressive brain mass. However, urgent investigations were normal. He was commenced on a loading dose of oral antiplatelet and acetylsalicylic acid then admitted for observation. Surprisingly, his neurological features resolved within 24 hours from the presentation. Therefore, the diagnosis of TIA was established.
