| Category | Percentage malignant - based on Curry et al.[1] |
|---|---|
| Bosniak I | 0% (4 cases) |
| Bosniak II | 0% (11 cases) |
| Bosniak III | 60% (29/59 cases) |
| Bosniak IV | 100% (18/18 cases) |
Note:
- Bosniak II is split into II and IIF.[2]
- IIF have minimally suspicious features and should get follow-up imaging.
