Radiological progression of Bosniak 2F cysts is low but may occur up to 24 months after diagnosis. Bosniak 2F lesions should be followed for 3-5 years; if stable or downgraded after that period of time, data would suggest, no further follow-up imaging is necessary.

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. Classification Bosniak 1 • simple cyst o imperceptible wall, rounded o work-up: nil Bosniak Classification of Renal Cystic Disease. The Bosniak classification was described in 1986. This classification helps the radiologist to categorize each cystic renal mass as "nonsurgical" (ie, benign in category 1 and 2) or as "surgical" (ie, requiring surgery in category 3 and 4).

Even though a consistent follow-up period is difficult to determine, due to the variable development time. Few Bosniak IIF class are hazardous and tumors of low-stage and low grade. Bosniak category 2F (''F'' for imaging follow-up), 3, and 4 lesions can have both benign and malignant etiologies, with malignancy rates increasing with increasing category. 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).

Hindman, MD Elizabeth M. Hecht, MD Morton A. Bosniak, MD Purpose: To determine percentage of Bosniak category 2F complex cystic renal masses that progress to malignancy based on serial follow-up studies,and to determine if there are demographic and/or imaging features associated with suggested that “the minimum follow up remains to be defined” • It is the policy of this department to follow Bosniak 2F Renal cysts by CT scans at 6 months, and 1 year, and then annually until 5 years • This policy may be varied to take into account the age and comorbidity of the patient Mean follow- up was 27 months. 56% cysts were >3cm at diagnosis.

Twenty years on since the introduction of type 2F, the diagnosis of many frequently encountered cystic masses still proves challenging, even to experienced radiologists. health, follow-up examination is suggested instead of intervention.
