BACKGROUND: To determine the sonographic features of @entity1897 . METHODS: This retrospective study included 54 cases of @entity808 in 51 @entity1 . Ultrasonography (US) and MRI were performed in all @entity1 . The US features of each @entity5 were analyzed and compared with pathologic findings. The US target sign was compared with the MRI findings. RESULTS: On US, 53 of the 54 @entity808 had a regular shape and clear margins, and one had an irregular shape. Thirty-seven of the 54 @entity808 were categorized as solid, 16 as cystic and solid, and one as entirely cystic; distal sound enhancement was associated with 47 @entity808 . The target sign was seen in 24, the @entity35 tail sign in 28, the vessel accompanying sign in 22, and the split fat sign in 5. The entering and exiting nerves were situated centrally in 9 and eccentrically in 19 @entity808 . Vascularity on color Doppler imaging using a 0 to III scale was graded 0 in 4 @entity808 , I in 10, II in 26, and III in 14. Twenty-four target signs were detected in 54 @entity808 by US, and 28 were detected by MRI. There was good agreement between the target signs noted on US and those seen on MRI (k   =   0.631, p   <   0.001). CONCLUSIONS: The sonographic diagnosis of @entity1897 is feasible and reliable. The target sign is a prominent US feature in @entity1897 , comparable to that observed with MRI.    2017 Wiley Periodicals, Inc. J Clin Ultrasound 00:000-000, 2017.
