title: Magnetic resonance imaging determination of the ventriculus terminalis.
abstract: We report a case of ventriculus terminalis, presenting with specific neurological symptoms including low back pain and bilateral sciatica. Magnetic resonance images showed a cystic lesion with regular margins localized in the lumbar enlargement of the spinal cord. The lesion was an oval shape with no internal septa. Its dimensions were 9.6 mm craniocaudally, 3.5 mm mediolaterally and 3.5 mm anteroposteriorly. Intralesional fluid had the same signal as cerebrospinal fluid in all magnetic resonance sequences. Pericystic spinal cord intensity was normal, and the cyst did not cause additional enlargement of the distal cord. During spinal cord evaluations, ventriculus terminalis should be kept in mind as a normal anatomic developmental phenomenon that can be seen on magnetic resonance images.
