Abstract
Cystic renal lesions are very commonly encountered at abdominal imaging. Most lesions are asymptomatic and incidentally found. When a confident diagnosis cannot be rendered, incidental renal masses are considered indeterminate and typically are furtherly evaluated with CT or MRI using Bosniak classification that is specifically designed to evaluate them.
To assess MRI in evaluation of cystic renal masses using Bosniak classification version 2019 to stratify the risk of malignancy in correlation to histo-pathological analysis.
This was a cross sectional study that included 60 patients who were diagnosed to have cystic renal lesion either outpatients or referred from the urology department at Ain Shams University Hospitals to the radiodiagnosis department For pelvi-abdominal MRI examination. An acceptance from the ethical committee of the Radiology Department and the ethical Committee of faculty of medicine - Ain Shams University hospitals was obtained to use the data stared on PACs system With the patient’s consent waived. All patients gone through MR assessment utilizing 1.5 T machine (inginea Philips).
From our study simple renal cyst (bosniak I) were the most common benign lesion and Cystic renal masses classified as Bosniak IV were the most common malignant lesion. After exclusion of benign causes 17 cases were included in histopathology. Clear cell Renal cell carcinomas were the most common finding and we correlate Histopathology with MRI results and It shows high significant relation between Bosniak classification and histopathology.
Bosniak classification version 2019 has high sensitivity and specifity in correlation to histopathology.
