Results Tornwaldt′s cyst were found in 18 of 1 452 cases (1 24%), all of the 18 cases were isointense to CSF on T 2WI and hyperintense to muscle on T 1WI.Tornwaldt′s cyst were round ( n =13)and ovoid ( n =5). The size of lesions were from 2 mm to 15 mm. There were 15 cases with adenoid hyperplasia. Conclusions Tornwaldt′s cysts occupied 1 24% in routine head MR imaging and were hyperintense to muscle on T 1WI and isointense to CSF ON T 2WI.
