Bosniak IIF: in diese Gruppe werden Zysten subsummiert, welche nicht eindeutig in Bosniak II oder III eingeteilt werden können und somit Nachkontrollen benötigen (F für follow-up), das Malignitätsrisiko beträgt 5 %. Median follow-up time was 27 months. We found that 98% of cysts were unchanged in their Bosniak score and 66% did not change in size. We followed up on 86 patients (43%) beyond two years: None had radiological progression. Four patients (2%) underwent partial nephrectomy secondary to radiological progression: One (0.5%) had histological malignancy. Se hela listan på academic.oup.com Cancers (2020-08-01) .

Besides Bosniak 2F, the other four include: Bosniak 1, Bosniak 2, Bosniak 3, and Bosniak 4. The Bosniak 2F type of kidney cysts has these characteristics: increased number of septa (thick walls of cysts); minimal thickening of septa; minimally complex but requiring follow-up tests (reasonable at around 6 months);
