FIG 2. Patient with 6.5/10 concordant, but mostly right-sided, occipital and mastoid pain with uncovertebral fissure.
A and B, Sagittal (A) and axial (B) MPGR images (3-mm thick, TE = 1015) show slight forward displacement of C2 on C3 (A). Axial image (B) appears normal. Because of the slight forward displacement of C2 on C3 (A), C2–C3 disk is judged to be abnormal.
C and D, Anteroposterior (C) and lateral (D) diskograms reveal an uncovertebral fissure and contrast leakage (arrows).
