Pancake-like gadolinium enhancement in the spinal cord: an image pattern that suggests spondylotic myelopathyA 55-year-old man without comorbidities presented with progressive paresthesia and weakness affecting the limbs. Cervical magnetic resonance imaging (MRI) demonstrated prominent spondylosis and myelopathy with pancake-like gadolinium enhancement (Figures 1 and 2).
Figure 1
Sagittal MRI reveals prominent cervical spondylosis associated with a fusiform longitudinally-extensive hyperintensity on T2-weighted image, below compression, due to spinal vasogenic edema (A), hypointensity on T1-weighted image (B), with a transverse pancake-like band of enhancement at the spinal cord just below the site of maximal stenosis (C3-C4) on T1-weighted post-gadolinium image (C).

The pancake-like sign is related to a focal disruption of the blood-brain barrier and defined by a circumferential enhancement sparing spinal cord gray matter on axial images, located beneath the site of maximum stenosis, with a transverse band appearance on sagittal images, extending less than one vertebral segment. The recognition of these radiological findings contribute to the avoidance of unnecessary interventions1,2,3.
