Imaging and histopathologic features of reversible nerve root and peripheral nerve edema secondary to disc herniation in a cat
Abstract Nerve root enlargement with increased contrast uptake has been reported in dogs and humans secondary to nerve root compression. In cats, nerve root enlargement and contrast uptake only have been reported in association with inflammatory and neoplastic diseases, but not as a sequela to nerve...
