Abstract

Study Design

Case report

Objectives

We report a case of relatively rare multiple bilateral perineural cysts.

Summary of Literature Review

Tarlov cysts, also known as perineural cysts are most often found in the sacral region, but there are a few cases reported in the thoracic region. In particular, there are very few cases of multiple bilateral thoracic perineural cysts.

Materials and Methods

A woman aged 65 years with perineural cysts in the bilateral T10-T11 and T11-12 neural foramens, underwent a T10-11-12 decompressive laminectomy and resection of the cyst.

Results

Satisfactory results were obtained for the patient after surgery.

Conclusions

For more detailed and definitive treatment of thoracic perineural cysts, additional cases are required.
