초록

흉요추의 후관절낭혈종은 아주 드문 질환이다. 저자들은 만성적인 요통과 우 하 방사통을 호소하는 69세 환자에서 12번 흉추와 1번 요추에서 발생한 우측 후관절낭혈종을 경험하여 증례 보고 및 문헌고찰을 하는 바이다. 자기공명영상과 자기공명척수조영술에서 척추관 우측 후방에 경막 외 비균질성 고신호 병변이 보였고 인접한 후관절과 연결되어 있었다. 수술적 소견으로는 얇은 막을 갖는 혈종으로 후관절과 연결되어 있었고, 조직학적 검사에서 혈종으로 확진 되었다. 자기공명영상과 자기공명척수조영술은 비침습적 검사로 병변의 특징적인 신호강도를 보여 줌으로써 진단과 치료에 큰 도움이 되었다.

A facet cyst is a very rare condition in the thoracolumbar spine and more so, hemorrhage into a cyst is extremely rare. We present a case of a facet cyst hematoma in the T12-L1 spine. A 69-year-old woman complained of chronic back pain with right lower extremity pain, and weakness for 3 years. MRI and MR myelography showed an extradural mass at the T12-L1 level with heterogeneous signal intensity on both T1-and T2-weighted images, which was continuous to the right T12-L1 facet joint. The neighboring facet joint showed severe degeneration on the CT scan. The mass a was simple hematoma covered with a thin fibrous membrane and connected with facet joint macroscopically and microscopically. The pathogenesis of the facet cyst hematoma is not clear but it can compress nerve roots or dura mater and cause radiculopathy or cauda equina syndrome. Surgical removal should be recommended for symptomatic relief.
