Presentation
The asymptomatic patient came for aortic evaluation after an EVAR procedure for abdominal aneurysm repair. A chest CT was performed as part of the pulmonary evaluation in a smoking patient.
Patient Data
CT chest without contrast, in axial, sagittal, and coronal reconstructions, showing diffuse posterior linear calcification of the spinal cord dura.
Case Discussion
Diffuse dural calcification along the posterior part of the dura, from the cervical spine through the thoracic spine, ending at the level of L1, was noted as an incidental finding in an asymptomatic patient.
As part of the differential diagnosis, the patient underwent investigation for hyperparathyroidism 1, which was negative, and renal function 2 is good.
Other differential diagnosis of dural calcification can be arachnoiditis ossificans, which considered to represent a changes caused by chronic arachnoiditis.
The patient does not have any other known clinically suspicious history.
