Later, a study by Smith et al [15] indicated that 54% of the category III cystic masses on CT were malignant. Above results showed that the Bosniak category on MR may cause upgrading and over-diagnosis in some cases, especially changing from II or IIF on CT to IIF or III on MR.

type 4: clearly malignant. They appear similar to type III cysts, but also have enhancing mural components adjacent to, but separate from the wall or septum. 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.

Slightly more than half of Bosniak III renal cysts and most Bosniak IV renal cysts are malignant at surgical pathology [1–3, 10, 11]. Biopsies from seventeen Bosniak 3 cystic lesions were pathologically analyzed and five (29%) were found to be malignant. Conclusion: Our results reveal a considerable malignancy rate among both 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).

IV These lesions are clearly malignant cystic lesions that contain enhancing soft-tissue components. TABLE 2 The amount of cystic calciﬁcation as a predictor of malignancy [14] Bosniak category N lesions Mean Ca score The two uncategorizable lesions had a mean enhancement of 26.8 H. CONCLUSION: The results of our study serve to underscore some limitations of the Bosniak classification system because most of our category II and all of our category III lesions were malignant, suggesting that minimally complex cystic renal masses may contain malignant cells. 2017-03-16 · tinguish cystic lesions from solid renal masses with necrotic components, which behave more aggressively.3 Hence, the characterization of these cystic renal masses is crucial to determine the best clinical approach to be adopted.
