Both the intra and extraconal spaces are normal in appearance. Normal globes.
Case Discussion
The MR radiographer requested a review of the images whilst the patient was on the MR table. On questioning the patient it was elucidated that 1 year prior to the scan she has undergone a cosmetic facial procedure involving the injection of collagen.
