“…One report discussed the case of a man with diffuse dural calcifications on CT, which aided in the diagnosis of adult hypophosphatasia. 11 Najefi et al 12 reported the first known case of cervical dural calcification secondary to X-linked hypophosphatemic rickets (XLHR). Although their patient presented with spinal cord compression from a combination of calcified dural plaques and ligamentum flavum, laminectomy revealed a flexible and noncompressive dura.…”

BACKGROUND Diffuse spinal dural calcification is a rare disorder associated with hyperparathyroidism, including the secondary forms associated with renal failure, osteodystrophy, and chronic hypocalcemia. Here, the authors report a rare case of diffuse dural calcification causing spinal cord compression with myelopathy, requiring decompressive surgery with duraplasty to achieve adequate decompression. OBSERVATIONS A 46-year-old male with a history of renal failure on dialysis presented with 2 months of progressive neuropathic pain, lower-extremity weakness, and nonsustained clonus. Spine imaging showed severe renal osteodystrophy with multilevel compression fractures and diffuse dural calcifications with areas of invagination causing severe spinal cord compression. Decompressive surgery was recommended. In surgery, a thickened and calcified dura was encountered with areas of buckling causing spinal cord compression. The invaginated area of the dura was resected and reconstructed with patch duraplasty. The patient’s neurological status remained unchanged postoperatively, and at the 6-month follow-up, the patient reported significant improvement in pain and muscle spasms. LESSONS Diffuse dural calcifications are a rare complication of prolonged dialysis and secondary hyperparathyroidism. When there is resultant spinal cord compression, this condition requires an intradural approach that addresses the thickened, calcified dura directly to obtain adequate spinal cord decompression.
