The role of ultrasonography in diagnosing cystic adventitial disease

BackgroundCystic adventitial disease is rare and often causes stenosis or even occlusion of the corresponding blood vessels.PurposeTo investigate the diagnostic value of color Doppler ultrasound in cystic adventitial disease.Material and MethodsA total of 40 patients with clinically suspected cystic adventitial disease were consecutively enrolled at Shandong Provincial Hospital Affiliated to Shandong First Medical University between May 2015 and October 2023. The ultrasonographic images of cystic adventitial disease were analyzed and the ultrasonographic features were summarized. All patients underwent both ultrasound and magnetic resonance imaging (MRI). MRI findings served as a reference standard and Kappa statistic was adopted to assess the level of agreement. The sensitivity, specificity, positive and negative predictive values, accuracy, and Youden index of color Doppler ultrasound as a diagnostic tool for the diagnosis of cystic adventitial disease were assessed.ResultsUltrasonography findings were positive in 19 patients with clinical suspicion of cystic adventitial disease. The diagnosis was confirmed by MRI in 20 patients. There was one false-positive and two false-negative by ultrasonography. The κ level of agreement between color Doppler ultrasound and MRI for the diagnosis of cystic adventitial disease was high. The κ value was 0.85. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy, and Youden Index of ultrasonography were 90%, 95%, 94.7%, 90.5%, 92.5%, and 0.85, respectively.ConclusionColor Doppler ultrasound can effectively evaluate the ultrasound characteristic of cystic adventitial disease and provide a reliable imaging basis for its early diagnosis and treatment.
