Abstract

Calcium pyrophosphate dihydrate deposition disease (CPPD) is an inflammatory arthropathy that is defined by the deposition of CPPD crystals in articular and periarticular structures. The cervical ligamentum flavum is a rare location of CPPD deposition. A 65-year-old woman was admitted with complaints of neck pain and a tingling sensation and numbness below the xiphoid process for 2 months. Magnetic resonance (MR) imaging and computed tomography (CT) revealed compression of the spinal cord due to a nodular calcified mass in or attached to the ligamentum flavum at the C4-5, C5-6, or C6-7 level. The patient underwent a laminectomy at C4-5, C5-6, and C6-7, and resectioning of calcified extradural nodules that impinged on the cervical cord. The operation resulted in a resolution of neck pain and hypoesthesia, except in the feet. Histopathological examination of the excised specimen revealed rectangular CPPD crystals. Here, we report a case of compressive cervical spine due to CPPD deposition disease of the cervical spine and describe the literature relevant to CPPD deposition disease of the cervical spine.
