BACKGROUND Intradural spinal arachnoid cysts (SACs) are a rare cause of spinal cord compression. Treatment is centered on decompression of the spinal cord via laminectomy or laminoplasty followed by resection or fenestration of the cyst. Although laminectomy or laminoplasty access may be needed to achieve the desired result, either procedure can be associated with more extensive surgical dissections and long-term spinal stability concerns, including postsurgical kyphosis. OBSERVATIONS The authors present a case of a cervical intradural SAC in a 4-month-old girl presenting with symptomatic compression. The patient was treated by laminotomy and endoscopic fenestration of the SAC with resolution of symptoms and no disease progression 10 months postoperatively, when the patient was 14 months old. LESSONS Microsurgical endoscopic fenestration of an intradural SAC can provide a less invasive means of treatment while avoiding the risks associated with more invasive approaches.
