These lesions are classified using the Bosniak system, which comprises four main categories: Bosniak 1, 2, 3, and 4. 2,3 Contrast-enhanced ultrasound (CEUS) can be used to characterize simple and complicated cystic lesions and can provide information on kidney vascularity and perfusion.

5 yrs ago a CT scan showed a Bosniak 3 cyst , an undertimined cyst with enhancement. The Urolgist after doing an MRI decided that it was a simple cyst. Last month a CT scan was done for a stomach problem and of that cyst showed again as complex cyst. Pretty much the same except it grew from 2.2 cm to 3 cm still enhancing and still classified as a undetermined cyst, Bosniak 3 still.

Bosniak Type III Cyst: (a) Measurable enhancement is present with Cystic mass, thickened irregular or smooth walls or multiple Septa. (b) These Cysts can be multiple in natures.

Smaller (<4 cm) Bosniak III cysts were more likely to be malignant and lesion size should be taken into consideration when considering management of complex cysts. Active surveillance may be a reasonable option for Bosniak III cystic lesions, regardless of overall size, based upon their universal low grade and no patient developing metastatic disease.

Mean lesion size was 4.6 cm (range, 1.1–8.1 cm) for Bosniak category III lesions and 3.5 cm (range, 1.2–22.0 cm) for Bosniak category IV lesions. The mean size of malignant lesions was 4.1 cm, and that for benign lesions was 3.4 cm, with no significant statistical difference noted (p = 0.387). Although the malignancy rate in surgically excised Bosniak IIF and Bosniak III cystic renal lesions was 25% and 54%, respectively, in our study, the malignancy rate was higher in patients with a The Bosniak classification system utilizes specific CT or MR imaging features to help classify cystic renal lesions into those that are likely benign (and do not require surgical resection) from those that are likely malignant (and thus require surgical resection). Bosniak Classification System for Cystic Renal Lesions. Bosniak III and IV category renal cysts have measurable enhancement in thickened walls or septa on CT or MRI studies, and the presence of well-defined nodular soft-tissue components differentiates Bosniak IV from III renal cysts [1–3].

Bosniak 2F depicts complex cystic lesions with complexity between Bosniak 2 and Bosniak 3 lesions and may have malignant potential in up to 5% of the cases. In contrast, Bosniak 3 cysts with enhancing thickened nodules (3n) are more similar to Bosniak 4 lesions; they are more likely to progress to Bosniak 4 on subsequent imaging studies and more likely to be malignant when resected (100% of 3n vs 41% of 3s).
