[Abstract] Objective: To explore the value of 3.0 T MRI virtual endoscopy reconstruction in mimetic convulsion.Materials and Methods: Thirty patients with mimetic convulsion received MR scan using FIESTA C sequence. The images were postprocessed with virtual endoscopy reconstruction on workstation. Relationship between vessels and nerves was analyzed in symptomatic side. Twenty two of 30 patients received microvascular decompression.Results: In symptomatic side of 30 patients, contact of vessels and nerves was found in 6 patients, and depression was found in 24 patients. Twenty four contact or depressions occurred in facial root emerging zone and six in nervi facialis distal to brainstem. Offending vessels included 11 anterior inferior cerebellar artery, 10 posterior inferior cerebellar artery, 6 arteriae vertebralis, and 3 arteriae basilaris. MRI showed the same offending vessels operative results, and the symptoms of mimetic convulsion disappeared after operation.Conclusions: 3.0 T MRI virtual endoscopy reconstruction has high clinical application value in hemifacial spasm, and plays an important role in etiological diagnosis and operation planning.
