A renal cyst is a fluid collection in or on the kidney. There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon. However, some are cancerous or are suspicious for cancer and are commonly removed in a surgical procedure called nephrectomy. Numerous renal cysts are seen in the cystic kidney diseases, which include polycystic kidney disease and medullary sponge kidney.

Bosniak revised the original classification system of renal cysts in 1993 to include a subset of category II lesions, category IIF cysts [5, 6, 14]. This category represents more complex cystic lesions, which cannot unequivocally be classified as category II or III.

The last ultrasound scan seemed to show that it had grown in the last year ( I've had it scanned yearly since it was found 5 years ago) it now measures 6 centimetres by 6 centimetres. Bosniak II: these are also benign cysts with a 0-5% chance of malignancy. These may contain a few hairline thin septa, fine calcifications in the cyst wall or septations, and are uniformly high-attenuated lesions <3 cm.

Biopsy seems to be a useful diagnostic tool prior to planning of an imaging follow Bosniak category III and IV cysts are lesions with progressive malignancy rates, and surgical resection is often considered on the basis of urologic guidelines [9–11]. A renal cyst is a fluid collection in or on the kidney. There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon. However, some are cancerous or are suspicious for cancer and are commonly removed in a surgical procedure called nephrectomy.

Cystic renal masses are commonly encountered in clinical practice. In 2019, the Bosniak classification of cystic renal masses, originally developed for CT, underwent a major revision to incorporate Results. The malignancy rate of resected Bosniak IIF lesions was 25% (four of 16) and that for Bosniak III lesions was 54% (58 of 107) (P = .03).Thirteen percent (nine of 69) of Bosniak IIF lesions progressed at follow-up, and 50% (four of eight) of these resected cysts were malignant.

Though Bosniak classification for renal cysts is used worldwide and underwent a number of modifications, Bosniak III cysts still have almost a 1:1 chance of being malignant. So the problem is that approximately half of the Bosniak category III cystic lesions prove to be benign after surgery. The classification system puts renal (kidney) cysts into five categories, depending on the findings on CT. Besides Bosniak 2F, the other four include: Bosniak 1, Bosniak 2, Bosniak 3, and Bosniak 4.

Also, there may be thick and nodular calcifications. Bosniak IV cysts have measurable enhancing nodular soft tissue components which are independent of the wall or septa. They are considered to be malignant until proven otherwise. 3 Results The cysts in the bottom row (2F, 3 and 4) should be followed (the "F" in 2F means it requires "followup") and require further evaluation and management. type I: almost universally benign and appear as simple cysts on CT with extremely thin walls. To classify a renal cyst as type I, there must be no septa, calcifications, or solid components.

The Bosniak 2F type of kidney cysts has these characteristics: increased number of septa (thick walls of cysts); minimal thickening of septa; pends on classification. Bosniak Iand II type cysts are lesions, that are considered to be benign and no follow-up is needed. Bosniak III and IV type cysts are the surgical lesions. In the Bosniak III category the risk of aggressive tumor is minimal, so nephron sparing surgery is recommended. Bosniak IIF is frequently discussed.
