Although being well known in neurology SI «Romodanov Institute of Neurosurgery of NAMS of Ukraine», practice, most of the physicians who have not experienced this Emergency Department of Vascular Neurosurgery, Kyiv, Ukraine phenomenon are unaware of this phenomenon since it is rare and can be confused with somatic complaints. This case report aims to Aim point out that NCS may be the first sign and symptom of metastatic To improve the results of surgical treatment of patients with cancers in patients who are not diagnosed. moyamoya disease based on the MSCT-perfusion (CTP) results. Case Material and methods We report a 52-year-old man who presented to our outpatient The retrospective analysis of surgical treatment was performed clinic with numbness on his right jaw for 1 month. He had a history patients with moyamoya disease (n = 5; m/w, 3/2; age range = 16– of renal transplantation and used immunosuppressive therapy. He 55 yrs) underwent brain CTP examination.

Recently, the use of metformin has SI «Romodanov Institute of Neurosurgery of NAMS of Ukraine», been shown to reduce the severity of stroke in patients with type 2 Emergency Department of Vascular Neurosurgery, Kyiv, Ukraine diabetes.
