title: The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis mimicking acute ischemic stroke.
abstract: Headache with neurologic deficits and cerebrospinal fluid lymphocytosis is a benign condition with a transient ischemic attack-like presentation. We present a case of a 22-year-old man with episodes of right-sided weakness, global dysphasia, and right-sided homonymous hemianopsia associated with frequent vomiting. Systemic thrombolytic therapy was considered. A subsequent magnetic resonance image with diffusion-weighted images revealed normal findings. A diagnosis of headache with neurologic deficits and cerebrospinal fluid lymphocytosis was made based mainly on clinical symptoms and cerebrospinal fluid analysis. With the current pressure on "door-to-needle" time for thrombolysis, it is important to keep an open eye to stroke mimics and exclude them if possible. We, therefore, strongly advise considering noninvasive magnetic resonance diffusion-weighted imaging in patients with unusual presentations (e.g., the vomiting in our patient) before thrombolysis.
