Abstract
Extraadrenal paragangliomas involving the spine is less common and usually
takes the form of intradural compression of the cauda equina. The authors
report three cases of spinal paragangliomas resulting in extradural spinal cord
compression and their MR findings. The MR imaging revealed a well-demarcated
extradural mass with low to intermediate signal intensity on T1-weighted
images and intermediate to high signal intensity on T2-weighted images compared
to paravertebral muscles. After Gd-DTPA administration, heterogeneous
and intense enhancement was found. Multiple punctate and serpiginous structures
of signal void due to high-velocity flow were noted around and within the
tumors on all sequences. In one case, the signal void structures were well corresponded
with feeding arteries on angiography. These may be the characteristic
findings of the extraadrenal paraganglioma involving the spine.
