Summary
This study reports the successful surgical treatment of the largest known Tarlov cyst, a type of perineural cyst. The procedure relieved the patient
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Perineural cysts, particularly Tarlov cysts, are frequently discovered incidentally on lumbosacral MRI.
- Symptomatic perineural cysts requiring intervention are less common than incidental findings.
Observation:
- A 29-year-old woman presented with chronic constipation and low-back pain.
- A massive presacral cystic lesion, identified as a large Tarlov cyst originating from the S-3 nerve root and compressing the S-2 nerve, was discovered during infertility investigations.
Findings:
- The patient underwent successful surgical treatment involving ligation of the cyst neck and sectioning of the involved S-3 nerve root.
- Postoperative assessment revealed significant improvement in the patient's symptoms and favorable magnetic resonance imaging (MR) findings.
Implications:
- This case highlights the successful surgical management of a notably large Tarlov cyst.
- Preoperative considerations such as precise nerve root identification, surgical indication assessment, and procedural planning are crucial for effective treatment, especially for multiple cysts.
