CaseIntensity of nodulesCyst diameter/nodule diameter (mm)Location and shape of nodules

2Homogenously hyperintense in T122.0/17.0Oval
9Hyperintense in T113.0/10.0Ball-like
10At the periphery, isointense in T1, isointense ring in T2; in the center, slightly hypointense in center on T1, slightly hyperintense in T2 with Bull’s eyelike changes15.0/7.0Ball-like
12Isointense in T2, slightly hyperintense in T2 with more homogenous distribution13.5/10.0Ball-like
13Hyperintense in T1, slightly hypointense in T211.0/7.9Triangle at sagittal images, similar to the outline of cyst in morphology
17Two nodules with homogenous intensity: (1) presence in T2, slightly hypointense in T2; (2) presence in T1, slightly hypointense in T111.0/7.011.0/6.3In the right lower and upper central part, ball-like
18Isointense in T1, isointense in T226.0/14.2In the lower part, ball-like
19At the periphery, slightly hyperintense in T1, slightly hyperintense ring in T2; in the center, isointense in T1, slightly hypointense in T2, suspected Bull’s eyelike changes14.6/4.1In the right lower part, ball-like
23Hyperintense in T1, hypointense in T218.0/8.0In the lower and middle part. Ball-like, atypical nodules
