High-dose computed tomography in the evaluation of low attenuation lesions in the neck

Recent reports have established the clinical utility of computed tomography (CT) in the evaluation of jugular vein thrombosis. Other abnormalities of the soft tissues in the neck can mimic this condition. This study reviews the pertinent normal soft tissue and vascular anatomy of the neck and describes the use of high-dose CT in the evaluation of low attenuation lesions in this area. Various abnormalities are compared and contrasted, including cystic hygroma, neoplasm, abscess, and venous thrombosis.
