Diagnostic performance of contrast‐enhanced ultrasonography and magnetic resonance imaging for the assessment of complex renal cysts: A prospective study

Objectives: To compare the diagnostic performance of computed tomography, magnetic resonance imaging and contrast enhanced ultrasonography for the assessment of complex renal cysts. Methods: We carried out a prospective single-center study from January 2012 to December 2013. We included patients with Bosniak category 2F or 3 renal cysts found on computed tomography and reviewed by two expert radiologists. Magnetic resonance imaging and contrast-enhanced ultrasonography were then carried out. Patients with a Bosniak ≥3 cyst on magnetic resonance imaging, as well as those upgraded as appearing malignant on contrast-enhanced ultrasonography, were surgically managed. Imaging results were compared with histological data. For patients without surgery, imaging examinations were compared with follow-up data. For each imaging examination, diagnostic performance and Cohen's kappa coefficient were assessed. Results: A total of 47 patients were included. The median follow up was 36 months (range 17-48 months). At initial computed tomography, cysts were classified as Bosniak 2F and Bosniak ≥3 in 34 and 13 patients, respectively. Magnetic resonance imaging found 13 Bosniak ≥3 cysts, and contrast-enhanced ultrasonography upgraded six more patients with cysts that appeared malignant. A total of 19 patients had surgery. Histological analysis reported 14 malignant tumors. No tumor progression was found in followed-up patients. Computed tomography showed poor sensitivity (36%) and specificity (76%; j = 0.11). Magnetic resonance imaging showed 71% sensitivity and 91% specificity (j = 0.64). Contrast-enhanced ultrasonography showed high sensitivity (100%) and specificity (97%), and a negative predictive value at 100% (j = 0.95). Conclusions: The present results suggested that contrast-enhanced ultrasonography could be useful in improving the assessment of complex renal cysts. Indeed, computed tomography accuracy might be limited in this indication requiring further investigations to determine the best treatment strategy.

Indeterminate cystic kidney lesions found incidentally on abdominal imaging are an increasingly prevalent diagnostic challenge. The standard workup includes Bosniak classification with contrast-enhanced CT or MRI. However, these tests are costly and not without risks. Contrast-enhanced ultrasound (CEUS) is a relatively new imaging technique with lower risk of adverse events than iodine-containing contrast or gadolinium. In our review of the evidence for characterization of cystic kidney lesions with CEUS, CEUS displayed sensitivity (89–100%) and negative predictive value (86–100%) comparable to contrast-enhanced CT or MRI with no decrease in specificity compared to CT and only a slight decrease compared to MRI.

Ultrasound, CT, and MR Imaging for Evaluation of Cystic Renal Masses

Cystic renal masses are often encountered during abdominal imaging. Although most of them are benign simple cysts, some cystic masses have malignant characteristics. The Bosniak classification system provides a useful way to classify cystic masses. The Bosniak classification is based on the results of a well‐established computed tomography protocol. Over the past 30 years, the classification system has been refined and improved. This paper reviews the literature on this topic and compares the advantages and disadvantages of different screening and classification methods. Patients will benefit from multimodal diagnosis for lesions that are difficult to classify after a single examination.
