a, The transverse computed tomography revealed an atypical, well-circumscribed homogeneous calcified mass attached the posterior globe in the left orbit. b, The coronal computed tomography showed a calcified mass neither origined from the globe nor the bony orbital wall. c, The transverse T1WI section showed the heterogeneous lesion .The lesion was approximately 17.7 × 14.1 × 24.2 mm in the orbit. d, The coronal T2WI section showed the heterogeneous lesion presents hypointense in the left orbit
