The authors report a case of a patient with diffuse idiopathic skeletal hyperostosis (DISH) associated with basilar impression resulting in tetraparesis.
To describe neurologic compromise associated with DISH.
Neurologic deficits due to DISH are very rare, and only 1 case of basilar impression associated with DISH has previously been reported in the literature.
Diagnosis was confirmed by radiograph and MRI, which demonstrated basilar impression associated with a hyperintense signal in the spinal cord on T2-weighted sequences. Transoral resection of the dens associated with posterior occipitocervical fixation was performed during the same anesthesia.
Postoperative outcome demonstrated regression of the pyramidal signs without recovery of unassisted walking.
Early MRI should be performed in the evidence of spinal cord suffering in patients with DISH. Transoral approach allowed a good decompression of the spinal cord.
