Diffuse vertebral body edema due to calcified intraspongious disk herniation

We describe the case of a patient with a recent history of high back pain, with magnetic resonance imaging (MRI) of the thoracic spine showing intervertebral disk herniation into the spongious bone of the vertebral body of T9 that might have caused diffuse, low signal intensity on fluid-attenuated inversion recovery T1-weighted (FLAIR-T1W) images, high signal intensity magnetic resonance (MR) on T2-weighted (T2W) images and T2-weighted fat-suppressed images (T2W-FSIs) and marked enhancement on the vertebral body of T9 with gadolinium on T1-weighted fat-suppressed images (T1W-FSIs) images. Those findings suggested diffuse edema and might be indistinguishable from tumoral or inflammatory diseases, but the plain films and the reformatted sagittal computed tomography scans of the thoracic spine were helpful to show a calcified part of the intervertebral disk migrating into the vertebral body of T9. The patient made full recovery from the symptoms after conservative treatment and at the follow-up MRI showed normalization of the bone marrow signal intensity of the vertebral body of T9.
