4%-15% of all RCCs Shows cystic growth morphology. 23 there are four examples of cystic growth morphology which are normal unilocular cystic growth, stereotypical multinodular cystic production, origins of a single cyst epithelium, or Because of their asymptomatic characteristic and non specificity of their clinical repercussions, renal lesions in general are incidentally diagnosed at images or necropsy (1-3). According to the literature, cystic lesions represent the most common findings in the radiologists' daily practice (2,4) and it is believed that they are acquired 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. All complex cystic lesions in the kidney (n = 550 in the same number of patients) were reclassified according to the Bosniak classification by two radiologists in consensus. If a patient had more than one lesion, only the highest Bosniak category was recorded.

Liver lesions are groups of abnormal cells in your liver. Your doctor may call them a mass or a Cystic masses with thin (<=2 mm) and few (1-3) septa; septa and wall may enhance; may have calcification of any type; Homogeneous hyperattenuating (>= 70 HU) Key Words: Kidney, renal, small renal mass, cyst, Bosniak classification, incidental finding Fig 3.

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. The Bosniak classification is widely used by radiologists and urologists for addressing the clinical problem assessing renal cysts 3.

While the malignancy risk of Bosniak III cystic lesions is thought to be approximately 50% , reported malignancy rates range from 31% to 100% .

Graden enligt Bosniak-klassificeringen avgör taktiken för undersökning och En njurecyst kan vara enkel (I Bosniak) och komplex (II, IIF, III och IV Bosniak). Om det finns flera cyster i en njure samtidigt talar de om en multi-cystisk lesion.

AJR Am J Roentgenol. 2003;181(3 Cancers 2020, 12, 2170 3 of 16 rates of almost 0%. 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). The authors conclude that septated cysts (2F and 3s) should be surveilled at 1, 3, and 5 years.
