Cysts with varying degrees of septae, calcifications, enhancing (with CT contrast) or solid components are called complex. Bosniak II cysts have the least amount of these, while Bosniak IV have the most. Bosniak III and IV have >40 and >80% risk of malignancy and should be followed with imaging for progression or removed. | Cysts with varying degrees of septae, calcifications, enhancing (with CT contrast) or solid components are called complex.
