Abstract :
Ventriculus terminalis or the fifth ventricle is a space full with CSF which is coated by normal ependyma cells in conus medullaris of medulla spinalis and observed rarely in adults. In the present case, findings obtained by magnetic resonance (MR) imaging associated with cystic dilatation of ventriculus terminalis were identified in an adult case. A 36 years old female patient referred by low back pain and thoracolumbar region images obtained by routin MR sequences were analyzed. A cystic dilatation with dimensions of 33x12 mm which is isointense with CSF was detected in the center of medulla spinalis at conus medullaris level (T11-12) in all MR sequences. Signal intensity of medulla spinalis was normal. No septation existed in the cyst detected. There was not any canal dilatation and additional spinal abnormality in canalis centralis, proximal side of medulla spinalis. Ventriculus terminalis which is identified as an ependymal space in conus medullaris rarely is observed coincidentally in MR images. Considering intensity of the imaging is useful to differantiate ventriculus terminalis from other cystic tumors located on the same site. Ventriculus terminalis generally progresses asymptomatically and treatment method is determined by clinical findings and whether the cyst is drained. MR imaging is quite important for diagnosis and follow-up of such variations.
