We report a case of patient with schizophrenia and persistent headache associated with a Blake's cyst, who underwent endoscopic third ventriculostomy (EVT). The data was collected through the review of the clinical history, interview with the patient, photographic records of the diagnostic methods and surgical treatment performed, in addition we reviewed the literature. Accurate diagnosis of Blake's cyst is extremely important; for this reason, it is essential to perform EVT, a resolving procedure with a low risk of complications and which is currently available within the neurosurgeon's therapeutic arsenal.
