Diffuse idiopathic skeletal hyperostosis: A case report

ABSTRACT

Diffuse idiopathic skeletal hyperostosis is a disease of old age, in which there is bony proliferation of spine in ventral and lateral aspects of vertebral body. A 80-years-old male presented to us with features of low back pain radiating along the right lower limb in the posterolateral aspect. After examination and investigations, he was found to have metabolic syndrome, degenerative lumbar disc disease, and his X-Ray and MRI showed diffuse thickening of lumbar vertebrae from L2-S1. This suggested that the patient had diffuse idiopathic skeletal hyperostosis with extraspinal manifestations which coexisted with lumbar degenerative disc disease. This case shows that both diffuse idiopathic skeletal hyperostosis and lumbar degenerative disc disease can coexist. Diffuse idiopathic skeletal hyperostosis should also be kept as a differential diagnosis in chronic low back pain in old age.
