Renal cell carcinoma (RCC) surveillance was not enhanced in the past 20 years. Only one IIF cyst showed radiological progression to category III after a follow-up of 42 months (progression rate of 2.5%). Twenty-two cysts increased in size (mean 10.7 mm, range 3–41 mm), 10 cysts showed reduction in size (mean 7.9 mm, range 3–17 mm) and 10 cysts remained stable. The flowchart (Fig. 1) shows that of 550 complex renal cysts ≥ Bosniak category II, 44 patients had moderately complex renal cysts categorised as Bosniak IIF. For those BIIF lesions with a follow-up period ≥2 years ( n = 32), the mean follow-up was 1,393 days (735–4,046 days). The reasons for re-section of the Bosniak IIF renal cysts included an increase in size (n = 2), resected along with a Bosniak III or IV renal cyst (n = 2), resected during workup for renal transplant (n = 2), temporary reclassification as Bosniak III renal cyst based on ultrasound (n = 1), and unknown (n = 1).

To classify a renal cyst as type I, there must be no septa, calcifications, or solid components. These lesions do not enhance with IV contrast. type 2: almost universally benign, but unlike type I, they may contain thin septa. Thin or slightly thickened calcification may be noted within the cyst wall.

2021-04-13 · Cysts are graded on a scale from 1 to 4 (Bosniak Classification). Bosniak 1 and 2 lesions are likely to be benign whereas Bosniak 3 and 4 lesions are more likely to be cancerous. What makes a growth on the kidney suspicious is when it appears to be solid on the imaging and when it "picks up" the dye that is used during CT or MRI scans (we call this enhancement). The malignancy risk of Bosniak III renal lesions was 60% in our study. All Bosniak III lesions were of low Fuhrman grade with no evidence of progression.
