Approximately one-half of small (< 4 cm) Bosniak category 3 and 4 cystic renal lesions were downgraded, and the majority (88%) of small Bosniak category 2F lesions regressed or remained stable during active surveillance. Therefore, small size should be a consideration for conservative management.

The Bosniak renal cyst classification was initially described 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.

The Bosniak classification system utilizes specific CT or MR imaging features to help classify cystic renal lesions into those that are likely benign (and do not require surgical resection) from those that are likely malignant (and thus require surgical resection). Bosniak Classification System for Cystic Renal Lesions

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. As a result, many Bosniak III masses are benign but treated (18, 19), resulting in unneeded procedural morbidity, decreased renal function, and excess health care costs (49 – 53). Bosniak category III cystic renal lesions are indeterminate in malignant potential and most commonly managed with surgical excision. While the malignancy risk of Bosniak III cystic lesions is thought to be approximately 50% (2), reported malignancy rates range from 31% (3) to 100% (4).

CT scanning is the gold standard diagnostic intervention in renal cystic disease, with MRI reserved as a second line modality. However, MRI findings can also be correlated to the classification due to its ability to identify similar characteristics as CT scans [ 3 ]. Bosniak IIF has many neoplasms, the most widely recognized malignant renal tumour was clear cell carcinoma, it represented fewer than 50% of malignant lesions. 4%-15% of all RCCs Shows cystic growth morphology.

2020-01-03 · Cystic renal lesions are a common incidental finding on routinely imaging examinations. Although a benign simple cyst is usually easy to recognize, the same is not true for complex and multifocal cystic renal lesions, whose differential diagnosis includes both neoplastic and non-neoplastic conditions.

A Bosniak 3 cyst will be cancerous 50% of the time and unless there are co-morbidities that preclude surgery are usually dealt with in a similar fashion to solid renal/kidney masses. If a kidney lesion is a solid mass, particularly one that picks up blood and thus “enhances” on contrast CT, it is considered malignant until proven otherwise.

IntroductionLe diagnostic de plus en plus fréquent de kyste rénal implique de savoir identifier et prendre en charge de manière adéquate les lésions ayant un potentiel de malignité. Le but de cet article de revue est de réaliser une mise au point sur les caractéristiques morphologiques, histologiques et thérapeutiques des tumeurs kystiques du rein.
