To evaluate complex renal cysts by CT scan or MRI, it is imperative to obtain the scan through the kidneys before IV contrast and after IV contrast during the same exam with the same parameters. Calcification in a cystic renal mass is not as important in diagnosis as is the presence of associated enhancing soft-tissue elements. This information should enable a reasonable approach to the management of calcium-containing renal cystic lesions. Secondly, what is a Bosniak type 1 cyst?

Renal cysts are most often simple and asymptomatic. Distinguishing simple renal cysts from solid tumours in the kidney does not represent a diagnostic challenge.

The Bosniak classification system provides a useful means of categorizing cystic renal lesions but places less emphasis on their underlying pathophysiology. Se hela listan på academic.oup.com Abstract Bosniak classification type 1 renal cysts (Type 1 renal cyst) are very frequent and do not warrant follow-up or specific treatment. Here, however, we report two cases of type 1 renal cysts that were diagnosed on CT, US, and gross pathology without a solid component.

Twenty-two cysts increased in size (mean 10.7 mm, range 3–41 mm), 10 cysts showed reduction in size (mean 7.9 mm, range 3–17 mm) and 10 cysts remained stable. Five patients died during surveillance and none of them had cause of death attributed to renal cancer or its complication.

Type II are the minimally complicated cysts.

Simple kidney cysts are very common as people begin to age; up to half of all people 50 years of age and older have at least 1 kidney cyst. Most people have a cyst in only 1 kidney, but the number of cysts and the risk of getting cysts in the second kidney increase as we get older. The Bosniak classification is widely used by radiologists and urologists for addressing the clinical problem assessing renal cysts 3. It was last updated in 2005 12 . A Bosniak classification, version 2019 11 has been proposed to increase the accuracy and include MRI features but does not yet (c. 2021) have widespread validation. 2009-12-01 type I: almost universally benign and appear as simple cysts on CT with extremely thin walls.

The Bosniak classification is a time-proven method for the imaging classification and management of these lesions. Knowledge of the pathognomonic features of certain benign Bosniak 2F/3 lesions is important to avoid surgery on these lesions (e.g., localized cystic disease, renal abscess). Simple renal cysts || kidney || renalA renal cyst or kidney cyst, is a fluid collection in or on the kidney.

Type II are the minimally complicated cysts. Type I and II can be ignored. Type II F are probably benign, but need to be followed. Type III and IV both are surgical lesions.
