Based on Cohen's weighted kappa statistic (k), inter-observer agreement was moderate for CEUS (k=0.49) and fair for CECT (k=0.36). Agreement between CEUS and CECT for both readers was fair (reader 1, k=0.24; reader 2, k=0.37). Historic points In 1983, using early computed tomography (CT) scan technology, renal cysts were discovered in 33% of patients in the same age group. The Bosniak renal cyst classification system was initially reported in 1986, using CT scan findings. the Bosniak classification has been widely adopted and accepted because it addresses a difficult clinical problem and is easy to apply by both radiologists and Urologists. The original classification has divided renal cystic disease into IV 2020-12-14 · 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 indeterminate 2 (Table 1).

Bosniak Class II F – This lesion is likely benign, but follow up imaging is suggested. The Bosniak classification of cystic renal masses, introduced in 1986 [ 1 ], stratifies the probability of malignancy on the basis of imaging characteristics and guides clinical management.
