Click 10-year-old boy with NOMID (Neonatal-onset multisystem inflammatory disease). Sagittal MRI of the right knee done at the age of 10 years old: T1WI-pre gadolinium (1.5 Tesla, TR/TE=400msec/8msec, Slice Thickness=3mm); Eccentrically enlarged physis of the distal femur and proximal tibia are predominantly hypointense due to the presence of calcification . An enlarged popliteal node is also noted, measuring 0.8cmx1.0cmx1.5cm (anteroposterior x width x craniocaudal)(black arrowhead). The patellofemoral joint space is obliterated.

Click 10-year-old boy with NOMID (Neonatal-onset multisystem inflammatory disease). Sagittal MRI of the right knee done at the age of 10 years old: T1WI- post gadolinium (1.5 Tesla, TR/TE=400msec/8msec, Slice Thickness=3mm; Omniscan?, 0.2mls/kg . The eccentrically enlarged physis of the distal femur and proximal tibia show minimal enhancement post contrast. The enlarged popliteal node is also seen to enhance.

Click 10-year-old boy with NOMID (Neonatal-onset multisystem inflammatory disease). Axial MRI of the right knee done at the age of 10 years old: (a) T2WI-fat saturation (1.5 Tesla, TR/TE=4290msec/72msec, Slice Thickness=4mm); There are areas of heterogenous high signal intensities with central hypointensities in the enlarged physis of distal femur and proximal tibia. The hypointensities represents calcification. There is an enlarged popliteal node.

Coronal MRI of the right knee done at the age of 10 years old: PD+T2 fat saturation (1.5 Tesla, TR/TE=2790msec/33msec, Slice Thickness=4mm); There are areas of heterogenous high signal intensities with central hypointensities in the enlarged physis of distal femur and proximal tibia. The hypointensities represents calcification. There is an enlarged popliteal node.
