This entity has its classification, among them is stroke, which can be due to two origins, either by hemorrhage or due to ischemia. As for its diagnosis, the clinical manifestations serve as orientation, however, the diagnosis as such, is by imaging studies such as CT and / or resonance. On the other hand, there are other studies that are also useful for diagnosis, however, these have their indications; lumbar puncture is indicated in the presence of vasculitis and in subarachnoid hemorrhage with normal CT. OBJECTIVE: To know the indications for the study of cerebrospinal fluid in stroke through a review of the literature in the last 5 years in the Pubmed database, which allows the physician to know these indications efficiently through this update. Conclusion: The use of cerebrospinal fluid study in case of stroke is recommended in patients with arteritis and/or vasculitis of infectious or non-infectious origin, as well as in cases of subarachnoid hemorrhage with an unaltered imaging study. This test will reveal the existence of an infectious process or the presence of blood and thus be oriented to an infectious vasculitis or subarachnoid hemorrhage respectively.
