BackgroundA high prevalence of significant extravascular findings is reported in patients who underwent computed tomographic angiography (CTA) of the pulmonary artery, abdominal aorta, and lower extremities for suspected vascular pathology.ObjectivesTo determine the incidence of significant extravascular findings in patients who underwent CTA of the whole aorta or abdominal aorta, and to determine the common clinical symptoms of patients who underwent CTA of aorta in whom these significant extravascular findings were usually found.MethodsWe retrospectively reviewed the cases of 187 patients who underwent CTA of whole aorta and 37 patients who underwent of CTA of abdominal aorta at King Chulalongkorn Memorial Hospital from January 2011 to December 2012. We measured the prevalence of significant extravascular findings and placed these findings into 3 categories. We reviewed the clinical history, further investigation, and also pathologic result of these extravascular findings.ResultsOf 336 extravascular findings in 210 (95%) patients, 41 (12%) provided a an alternative explanation for symptoms of acute chest pain and acute abdominal pain, including axial skeletal fracture, pneumohemothorax, and hemopericardium associated with trauma, 85 (25%) were incidental extravascular findings that required radiological follow-up or further investigation including indeterminate lung nodules or lesions, liver masses, significantly enlarged lymph nodes, adrenal nodules, and mediastinal lesions, and 210 (63%) were extravascular findings that required less urgent or no follow-up. Nine (12%) patients received diagnoses of previously unknown malignancy.ConclusionsRadiologists and referring clinicians should be aware of the frequency of significant extravascular findings.
