Measurement of prevertebral soft tissue is commonly used to assess prevertebral abnormalities, such as retropharyngeal abscess or injury to the cervical spine. In the presence of goitres, the widened prevertebral tissue seen on plain lateral neck radiograph may be diagnostic of an enlarged tubercle of Zuckerkandl (ZT), which may be responsible for most pressure symptoms. The aim of this study was to substantiate the value of plain lateral neck radiographs in preoperative demonstration of enlarged ZT.
