More research is still necessary, but this is what we know so f We performed this review 1) to assess malignancy risk in the different Bosniak categories and 2) to assess long-term oncologic outcome of patients treated in. 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  This situation is a special concern when the intraparenchymal cysts are smaller than 1 cm [2]. There are technical disadvantages for magnetic resonance imaging (  Cysts are graded on a scale from 1 to 4 (Bosniak Classification). Bosniak 1 and 2 lesions are likely to be benign whereas Bosniak 3 and 4 lesions are more likely  Bosniak I-II cysts do not require any further imaging or follow up.

B-mode  category IV cyst, which is a malignant cystic tumour (Fig 1).

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. In the past, renal cyst masses were either classified as simple cysts or complicated cysts. In 1986, 1 Bosniak classifications were adopted and revised many times, most significantly in 2005. 2 It was used as an effective method to determine renal cystic masses. It has been widely recognized and used by various radiologists and urologists, based on general agreement between experts for a long The malignancy risk of Bosniak III renal lesions was 60% in our study. All Bosniak III lesions were of low Fuhrman grade with no evidence of progression.

M.A. Bosniak has recently suggested that BIIF cysts with minimal findings only need follow-up for 1–2-years, whereas more complex BIIF cysts should be followed for a longer period (e.g., 3–4 years or longer) .

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. the benign simple cysts (Bosniak I) and the clearly malignant Bosniak IV lesions. Category 1 and 2 lesions (simple cysts and mildly complicated cysts, respectively) are straightforward to diagnose and are benign, not requiring additional follow-up. Category 4 lesions (typically cystic neoplasms) are also easily diagnosed as neoplastic and require surgery. I have Bosniak-2 cysts, and your doctor is correct Type 1 & 2 are rarely cancerous. Type 3 & 4, they're another story, but 1 & 2 aren't USUALLY cancerous.

Here, however, we report two cases of type 1 renal cysts that were diagnosed on CT, US, and gross pathology without a solid component.

Bosniak 1–2 cysts very seldom contain cancer, whereas Bosniak 4 cysts (which contain nodular, soft-tissue components) very frequently harbor malignancy. As initially described, Bosniak 3 cysts have about a 50% chance of malignancy. Since Bosniak’s initial publication in 1986, July last year he noticed a lump at the side of his tummy, went to the doctor who thought it was a cyst, sent him for ultrasound and CT, he went for the ultrasound and they found 2 what they thought looked like cysts, both about 14cm so very big, he then went for CT and they said the same, the letter Said Bosniak cysts … 2011-03-14 Clinical Outcomes of Bosniak Category IIF Complex Renal Cysts in Korean Patients Jong Ho Hwang, Chang Ki Lee, 1 Ho Song Yu, 1 Kang Su Cho, 1 Young Deuk Choi, 1 and Won Sik Ham 1 Department of Urology, Sahmyook Medical Center, Seoul, Korea. 2016-10-19 Smaller cysts, usually <1 cm in diameter, also occur in medullary sponge kidney, autosomal recessive PKD, and autosomal dominant interstitial kidney disease An update of the Bosniak renal cyst classification system.
