Overview
A liver mass may be classified into several sub-types based on number of nodules, type of histo-pathology, and consistency.
Classification
A liver mass may be classified into several sub-types based on number of nodules, type of histo-pathology, and consistency.[1][2][3][4][5][6][7][8][9][10][11]
- Based on the number of nodules diagnosed on imaging liver mass can be classified into 2 types.
- Solitary nodule
- Multiple nodules

- Based on the type of histo-pathology liver mass can be classified into 2 types.
- Benign
- Malignant

- Based on the consitency of the mass, liver mass can be classified into 2 types.
- Complex cysts
- Solid cysts

- Clinically a liver mass can be classified into 3 catogeries
- Benign mass lesions for which no treatment is needed
- Benign mass lesions for which treatment is needed
- Malignant mass lesions for which treatment is always required
