RT Journal Article SR Electronic T1 Acute internal jugular vein thrombosis associated with pseudoabscess of the retropharyngeal space. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 892 OP 896 VO 16 IS 4 A1 L B Poe A1 J V Manzione A1 J J Wasenko A1 R M Kellman YR 1995 UL http://www.ajnr.org/content/16/4/892.abstract AB We present four patients in whom evidence of edema or a pseudomass in the retropharyngeal space was found on CT scans obtained after thrombosis of the internal jugular vein. The clinical condition of one patient led to surgery, which documented the sterility of the retropharyngeal space despite the CT appearance of an inflammatory process. The CT findings, which are confusing initially, are found to be typical in retrospect.
