CTICasesSyringopleural Shunt
Imaging findings
Spinal CT and a CT myelogram demonstrate contrast in the epidural space and a shunt catheter terminating in the central spinal cord within a syrinx. The catheter tracks through the subcutaneous tissues and terminates in a reservoir located in the pleural space, sitting within the major fissure.
Key takeaways
A syringopleural shunt is a specialized neurosurgical device used to treat a syrinx by draining cerebrospinal fluid into the pleural space, utilizing the negative intrapleural pressure to facilitate drainage. The device contains a one-way valve to prevent retrograde flow of pleural fluid or infection into the spinal cord and can be seen as an incidental catheter looping through the pleural space on chest imaging.
