CPPD 결정침착 질환에 의한 경부 측수증(cervical myelopathy) 1예

저자들은 우측 상지와 하지의 근력약화와 강직성 보행장애가 있어 내원한 57세 여자 환자에서 CPPD 결정침착 질환에 의한 황색인대의 칼슘침착과 그에 수반된 경부 측수증 1예를 경험하였기에 보고하는 바이다. Calcium pyrophosphate dihydrate (CPPD) deposition disease is an inflammatory arthropathy that is defined by the deposition of CPPD crystals in articular and periarticular structure. Spinal involvement in CPPD deposition disease is rare. We reported a rare case of CPPD deposition disease that caused compressive cervical myelopathy. A 57-year-old woman was admitted to the hospital with 1 week history of progressive paresis of the right upper and lower extremities. Computed tomography showed the round and nodular calcified ligamentum flavum. Magnetic resonance imaging showed a low intensity epidural mass pressing and distorting the cervical cord at C-4 and 5 levels on both T1 and T2- weighted images. Radiographic findings were consistent with calcification of the ligamentum flavum in the C-4 and 5 levels causing cord compression. The lesion was eventually removed by hemilaminectomy. The mass was composed of a very hard crystal like calcified deposition in the ligamentum flavum. The histopathological evaluation of the exicised ligamentum flavum revealed the characteristic crystals of CPPD. KCI Citation Count: 0
