1. Patient 12.
Patient 12. Both readers missed a defect found at endoscopy. Coronal MPR image from mm axial dataset missed a subtle defect of the right cribriform plate, measuring 3 mm endoscopically and 2 mm by imaging. Two defects were present on the right in this patient; readers detected the first, but not the second, defect. In retrospect, a small amount of soft tissue or fluid attenuation extends medially along the horizontal insertion of the middle turbinate, or olfactory recess, through the skull base defect.
