Bosniak 2F renal cystic lesions feature morphologic characteristics between Bosniak I and III categories, the majority of which remain benign. However, a minor part of Bosniak 2F lesions may progress to malignancy. The purpose of this study was to assess Bosniak 2F cystic lesions during follow-up examinations by CEUS. One-hundred-and-twelve out of 364 patients with Bosniak 2F lesions underwent Follow-up studies were from 6 months to 13 years (median, 3.6 years; average, 4.2 years).

The Bosniak classification system of renal cystic masses divides renal cystic masses into five categories based on imaging characteristics on contrast-enhanced CT. It is helpful in predicting a risk of malignancy and suggesting either follow up or treatment. Of the initial 83 Bosniak category 2F lesions, 37% (31/83) were downgraded to Bosniak category 1 or 2, 51% (42/83) remained Bosniak category 2F, and 12% (10/83) were upgraded on follow-up imaging. Of the initial 37 Bosniak category 3 lesions, 43% (16/37) were downgraded, and 57% (21/37) remained Bosniak category 3 or progressed to category 4.
