A 46 year-old woman presented with loss of pin sensation over the trunk associated with urinary urgency and frequency. |
| Syringomyelia (Syrinx):
(Left) T2-weighted sagittal MRI
scan of the thoracic spine; (Right) T2-weighted axial MRI at the level of T3. On
the sagittal scan, note the
two central cystic cavities. The rostral one expands the spinal cord and has septae within it.
A syrinx often
first presents with bilateral upper extremity loss of pain and temperature
sensation from early involvement of the crossing spinothalamic fibers.
Syringomyelia is often associated with congenital malformations, intrinsic cord
tumors, or may follow spinal trauma. |
