Management of symptomatic cervical facet cyst with cervical interlaminar epidural block: A case report

초록

BACKGROUNDSymptomatic cervical facet cysts are relatively rare compared to those in the lumbar region. These cysts are usually located in the 7(th) cervical and 1(st) thoracic vertebral (C7/T1) area, and surgical excision is performed in most cases. However, facet cysts are associated with degenerative conditions, and elderly patients are often ineligible for surgical procedures. Cervical interlaminar epidural block has been used in patients with cervical radiating symptoms and achieved good results. Therefore, cervical interlaminar epidural block may be the first-choice treatment for symptomatic cervical facet cysts.CASE SUMMARYA 70-year-old man complained of a tingling sensation in the left hand, focused on the 4(th) and 5(th) fingers, for 1 year, and posterior neck pain for over 5 mo. The patient's numeric rating scale (NRS) score was 5/10. The patient was diagnosed with symptomatic cervical facet cyst at the left C7/T1 facet joint. Fluoroscopy-guided cervical interlaminar epidural block at the C7/T1 level with 20 mg triamcinolone and 5 mL of 0.5% lidocaine was administered. The patient's symptoms improved immediately after the block, with an NRS score of 3 points. After 3 mo, his left posterior neck pain and tingling along the left 8(th) cervical dermatome were relieved, with an NRS score of 2.CONCLUSIONA cervical interlaminar epidural block is a good alternative for managing symptomatic cervical facet cysts.
