Abstract: Perineural or Tarlov cysts (TCs) are nerve root cysts. They are usually incidental findings on MRI and are most frequently observed in the sacral spine. A 49-year-old woman presented with lower abdominal discomfort for several months. Physical examination demonstrated a cyst-like mass. An ultrasonographic examination revealed a cystic mass near the right ovary. MRI (3-Tesla unit) showed multiple, bilateral, and almost symmetric giant TCs with presacral space and endopelvic extension and minime scalloping. TCs originated from the right and left L5, S1, S2, and S3 nerve root sleeves entered the presacral space and extended into the pelvis.

Keywords: presacral mass, perineural cyst, giant schwannoma, adnexal disease, giant cyst
