Abstract

Calcium pyrophosphate dihydrate (CPPD) crystal deposition disease is characterized by chondrocalcinosis, which mainly affects the knees, wrists, pelvis, and rarely, the spine. According to previous reports, CPPD crystal deposits display heterogeneous enhancement on MRI. When combined with inflammation of the surrounding soft tissue, strong enhancement by CPPD crystal deposition may appear similar to imaging features of other conditions such as infectious spondylitis. In these conditions, CT plays an important role in differential diagnosis. Here, we present a case of CPPD crystal deposition disease in the ligamentum flavum of the cervical spine that showed intense enhancement on MRI.

칼슘수산화인회석(calcium pyrophosphate dehydrate; 이하 CPPD) 결정침착질환은 연골석회증을 특징으로 하는 질환으로, 주로 무릎, 손목, 골반, 드물게는 척추를 침범한다. 이전 보고에 따르면, CPPD 결정침착은 MRI에서 불균질하게 조영증강이 될 수 있다. 주변 연부 조직의 염증과 동반된 CPPD 결정침착의 뚜렷한 조영증강은 감염성 척추염 등 다른 질환과 유사한 영상 소견을 보일 수 있다. 이 경우 CT는 감별진단에 중요한 역할을 한다. 저자들은 MRI에서 황색인대에 저명한 조영증강을 보이는 CPPD 결정침착 증례를 보고하고자 한다.
