The T1-weighted sagittal MRI of the vertebral column showed inflammatory involvement of T4/T5 vertebral bodies and coexistence of intervertebral disc involvement.

A magnetic resonance imaging (MRI) of the vertebral column showed T4/T5 vertebral bodies involvement by inflammatory tissue involving the spongy bone, hypointensity in T1-weighted and hyperintensity in T2-weighted/STIR with contrast enhancement and coexistence of involvement of the intervertebral disc (Fig. 1).
The T1-weighted coronal MRI of the sacroiliac joints showed a left non-homogeneous spongy hypodensity pattern, associated with enlargement of the articular interline and small joint effusion.

MRI of the sacroiliac joints revealed at the level of the left iliac and the left anterior and superior slopes of the S1 wing, a non-homogeneous spongy hypodensity pattern at T1-weighted, with marked hyperintensity at T2-weighted with fat suppression, demonstrating contrast enhancement/uptake, in an area of trabecular oedema, which is also associated with enlargement of the articular interline and small joint effusion suggestive of sacroiliitis (Fig. 2).
