Symptomatic Tarlov's Cyst(Sacral Meningeal Cyst) - Case Report -

Spinal meningeal cyst of the sacrum is uncommon congenital lesion. We experienced two cases of sacral meningeal cyst, so called Tarlov's cyst, who presented with radiating pain. Magnetic resonance imaging is a highly effective way of locating and approximating the size of these entities, which generally appear as intraspinal masses of low intensity on T1-weighted and high intensity on T2-weighted images, similar to cerebrospinal fluid(CSF). We evaluated 2 patients who had Tarlov's cyst diagnosed with conventional MRI. The clinical features, radiological findings, gross appearances of the lesion at surgery, surgical technique, histopathological features of the cyst wall, and surgical outcome are described. We conclude that excellent result can be expected in the case of symptomatic Tarlov's cyst by surgical decompression.
