CT appearance of syringohydromyelia

The authors report on twelve cases of syringohydromyelia diagnosed by CT. The findings recorded are divided into four groups depending on the size of the cord and cavity. Comparison between enhanced and unenhanced CT scans is performed in an attempt to demonstrate that central cord cavitation is clearly seen even without enhancement. It is thus proposed that unenhanced CT should be the examination of choice in syringohydromyelia.
