“…Sacral meningoceles are usually a type of dysraphism and are thought to take place during embryologic development. These lesions are frequently identified in the posterior location over the thoracic and sacral areas at birth and constitute about 10% of all patients with spina bifida (16).…”

We aimed to incidental findings discovered in patients with suspected low back pain disease undergoing MRI of the lumbar spine and the clinical importance of those findings. Material and Methods: One thousand seven hundred fourteen patients included who were admitted to our hospital with a preliminary diagnosis of low back pain were examined. The duration of low back pain complaints of the patients was ranging from 1 week to 4 years. MRI examinations were interpreted by academic neuroradiologists who had 7 years of experience, at the time of the study. Results: Overall, 358 patients (20.9%) had incidental findings. Transitional vertebrae was the most common (134 cases, 7.8%) incidental finding, followed by vertebral hemangioma (65 cases, 3.8%) and Tarlov cyst (54 cases, 3.2%). The incidence of fatty filum terminale, compact bone island, spina bifida, synovial cyst and sacral meningocele was 2.1%, 1.5%, 1%, 0.8% and 0.7% respectively. Of these 1714 patients, 329 patients (92.06%) had one finding, 22 patients (5.95%) had two findings, and 7 patient (1.98%) had three findings. The conus medullaris was terminated in 1710 (99.7%) of the patients (L1-2) .This level were considered normal. In four cases, the spinal cord was determined to be below the required level. The prevalence of transitional vertebra was 7.8%. The prevalence of sacralization and lumbalization was 5.1% and 2.7%, respectively. Conclusion: In this study we showed that incidental findings are mostly benign but interestingly there were no malignant or potentially malignant incidental lesions.

“…Incluidos en este grupo se describe el meningocele sacro anterior, que corresponde a una extensión de la duramadre y la aracnoides fuera del canal espinal del sacro hacia el retroperitoneo y espacio intraperitoneal a través de un defecto sacro ventral (3) . Estas lesiones expansivas pueden manifestarse clínicamente con dolor axial y síntomas relacionados con la compresión del cordón o la raíz (4) .…”

Arachnoid cysts are cerebrospinal fluid collections in the spine that can present with neurological symptoms or be discovered accidentally. Intradural location of such cysts especially in the lumbosacral region is relatively rare. The association of such cysts with other congenital anomalies such as tethered cord lends evidence to the developmental origin of arachnoid cysts. We report a case of lumbosacral arachnoid cyst with tethered cord in a 6-year-old male child and discuss the etiopathogenesis and management options.
