Imaging assessments of how Category 2F cyst progressed depends on whether enhanced stable tumour sections have occurred or on the length, quantity or variability of enhanced septa or thickness of the enhanced surface lesion. 34 Depending on the unusual malignancy of Bosniak IIF renal cysts, the American College of Radiology (ACR) recommended

A radiology database was retrospectively searched from january 1 1996 through may 1 2011 for all contrast agent enhanced computed tomographic ct or magnetic resonance mr examinations in which the terms renal or kidney and cyst cystic complex mass lesion indeterminate or bosniak. A system to grade kidney cysts by their appearance on CAT scan has been developed, which help doctors to predict which complex kidney cysts are more likely to have kidney cancer inside. This system is known as the Bosniak classification. The Bosniak classification provides specific definitions to classify cysts by the risk of kidney cancer. A simple cyst may not cause any symptoms. However, if the cyst grows large or becomes infected, it may cause symptoms such as: fever; pain in your back or side between your ribs and pelvis (the Simple kidney cysts are commonly observed in normal kidneys, with an increasing incidence as individuals age [ 1 ]. They are benign, asymptomatic lesions that rarely require treatment.

The Bosniak renal cyst classification system was initially report Optimal management of renal cysts in pediatric practice remains elusive. 43(21 %) were Bosniak 2F or higher. 48 (23.41%) children required surgery. Cyst characteristics (size and complexity) 24(50%) and patient symptoms (pain/ hematuri Diagnostic dilemma: Calyceal diverticulum vs complicated cyst lower abdominal pain and tenderness without hematuria or lower urinary tract symptoms.

There were no deaths from Bosniak IIF or III renal cysts regardless of management ablation for the treatment of biopsy-proven malignant cystic renal masses.

To this end, in 1993, Bosniak proposed a diagnostic criteria for CT in grade IIF (F-fallow up follow-up) for moderately complex cysts: 1 uniform wall thickness and uniform thickening. 2 increased calcification. 3 The wall and partition can be slightly strengthened. 4 High-density cysts ≥ 3 cm in diameter and completely within the renal parenchyma.

It measures as water density and does not enhance ±0% II A benign cyst that may contain a few hairline thin septa in which ‘perceived’ enhancement may be present. Renal cyst classification is based on their appearance and enhancement on CT and was introduced by Bosniak in 1986 with the most recent revision in 2003 [1 Eknoyan G. A clinical view of simple and complex renal cysts. J Am Soc Nephrol 2009; 20: 1874-6., 11 Israel GM, Bosniak MA. An update of the Bosniak renal cyst classification system. The Bosniak 2F type of kidney cysts has these characteristics: increased number of septa (thick walls of cysts); minimal thickening of septa; minimally complex but requiring follow-up tests (reasonable at around 6 months); the presence of hyperdense cysts which are over 3 cm in diameter; risk of malignancy: 0 to 5%. Keywords: Bosniak 2F type of kidney cysts; Bosniak 2F; Bosniak 2F type of renal cysts. Bosniak 2F Renal Cysts The Bosniak system is used to classify cystic renal masses seen on imaging, and the classification is shown in the table below. The Bosniak Classification (Warren, & McFarlane 2005) It is usually easy to differentiate between lesions at the ends of the spectrum, i.e.

We retrospectively analysed patients diagnosed with complex renal cysts classified as Bosniak IIF on contrast computed tomography imaging in our centre

Purpose: 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 Mean follow- up was 27 months. 56% cysts were >3cm at diagnosis. 98% cysts were unchanged in appearance, whilst 66% did not change in size.

Simple kidney cysts are commonly observed in normal kidneys, with an increasing incidence as individuals age [ 1 ]. They are benign, asymptomatic lesions that rarely require treatment. However, complex cysts may require follow-up imaging, biopsy, or surgical excision for diagnosis.

These cysts may demonstrate an increased number of septa or minimal smooth thickening of the wall or septa. The wall and/or septa may contain calcifications.
