RATIONALE: @entity3438 are sensitive to radiation therapy and chemotherapy; therefore, correct imaging diagnosis is crucial for them. However, the imaging findings of @entity3438 originating from off-midline regions displayed different patterns from those originating from midline areas. @entity1 CONCERNS: The objective of this study is to describe the radiologic features of primary @entity3438 . We reviewed the MR and CT findings of 12 @entity1 with histologically proven off-midline @entity3438 with off-midline locations. INTERVENTIONS: All of these @entity1 underwent conventional MR images and 3 of them underwent diffusion images. Additional CT images were available in 3 @entity1 . Analysis was focused on the shape and entity of @entity5 in images, signs of @entity5043 , and the involvement of fibers in diffusion images. OUTCOMES: Well-defined (8/12) and ill-defined margin masses (4/12) were identified according to the shape of the mass. Multicystic masses were seen in 11 of the 12 @entity1 . The solid component of the @entity5 had a high density (3/3) with @entity730 (2/3) on CT images, iso- to hypointensity in T2WI (11/12) and restricted diffusion on apparent diffusion coefficient (ADC) maps (3/3). @entity5043 was observed in 5 cases and progressive @entity5043 was observed in 1 case. Other signs included mild @entity4 (10/12), and @entity1276 (7/12). Additionally, infiltration of the corticospinal tract (CST) was identified on diffusion tensor imaging (DTI) (2/2). LESSONS: The results indicate that multicysitic entities and hypointensities in solid components on T2WI and @entity5043 are the imaging features of @entity3438 . DTI has potential for assessing CST involvement.
