CEUS ON RENAL CYSTS Michail Papagiannakis Radiology department SÄS 2013 CEUS=Contrast Enhanced UltraSound A quite new promising method characterising micro-circulation using micro bubbles It can be used on anything ultrasound waves can reach.(L.Thorelius,CEUS International Course Hanover, 2008) Spatial resolution :Ultrasound>MRI>CECT 2018-05-22 Bosniak 3 lesions can be hyperdense when imaged using computed tomography (CT). 2 Approximately half of all observed Bosniak 3 lesions in a series were found to be benign, and half were found to be malignant. 7,8 In benign Bosniak 2 or 3 lesions there is no enhancement within the cyst or the cyst wall. A Bosniak 2 cyst has a less than 1% chance of being malignant. They may or may not be followed based on the clinician’s judgment.

The Bosniak classification system of renal cystic masses divides renal cystic masses into five categories based on imaging characteristics on contrast-enhanced CT. It is helpful in predicting a risk of malignancy and suggesting either follow up or treatment. To determine percentage of Bosniak category 2F complex cystic renal masses that progress to malignancy based on serial follow-up studies,and to determine if there are demographic and/or imaging features associated with progression.

The current classification contains five categories: I, II, IIF, III and IV. Categorie I and II lesions are assumed benign and do not require further treatment. A IIF lesion is possibly benign and surveillance is 2020-12-14 · The currently used definitions of renal cysts are quite limited. The Bosniak classification is a CT-established classification initially conceived in 1986, with Bosniak 1+2 being benign and Bosniak 4 regarded as malignant. 1 It was later updated in 2012 with the addition of Bosniak 2F, which is likely benign, and Bosniak 3 considered as The Bosniak classification categorizes renal cysts into five groups.

Type I cysts are simple cysts. 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. But the urologist said that their were several kidney cysts, and classified them as Bosniak 2F. He advised having ultrasounds every 6 months to see if they were changing or enlarging.

Bosniak 2f cyst ultrasound

However, a minor part of Bosniak 2F lesions may progress to malignancy. The purpose of this study was to assess Bosniak 2F cystic lesions during follow-up examinations by CEUS. Bosniak 2F • minimally complex o increased number of septa, minimally thickened with nodular or thick calcifications o there may be perceived (but not measurable) enhancement of a hairline-thin smooth septa o hyperdense cyst >3 cm diameter, mostly intrarenal (less than 25% of wall visible); no enhancement The discovery of Bosniak Category IIF is considered as a successful method in renal cyst diagnosis and treatment possibly resulting in nephron-sparing during complicated renal cyst care. Keywords: kidney neoplasms, carcinoma, bosniak classification But the urologist said that their were several kidney cysts, and classified them as Bosniak 2F. He advised having ultrasounds every 6 months to see if they were changing or enlarging.
