CES has multiple etiologies (Figure 1). Trauma is an obvious
source. Blunt or direct spinal injury through the cauda
equina can cause significant injury. Sacral fractures, as
described by Bonnin, can also cause CES.3,17 Hematomas,
abscesses, lymphoma, solid tumors, and other spaceoccupying lesions that compress nerve roots have been
described as causes of CES.
Arslanoglu and Aygun18 recently reported a case in
which ankylosing spondylitis eroded the posterior elements
and traction on the lumbar nerve roots and led to
CES. Mohit and colleagues19 described how an inferior
vena cava thrombosis led to CES in a 16-year-old patient
and how an inferior vena cava thrombectomy was required
to relieve symptoms. The literature includes fewer than
20 reports of cases in which sarcoidosis caused CES; the
most recent report, by Kaiboriboon and colleagues,20 was
published in 2005
