Hydatid cysts of the liver: TN(R)C classification.
BACKGROUND
Liver hydatid disease remains a serious public health problem. Its incidence is increasing but still there is no standardised protocol for assessment of the severity of the disease or for classifying the lesion in each individual case.


OBJECTIVE
To construct a new and maximally descriptive classification system that could help in better assessing the extent of the disease, both in primary and recurrent cysts.


METHODS
Description of a newly created classification system.


METHODS
University hospital.


METHODS
Review of the literature and own observations.


RESULTS
Classification system describing T (topography of the cyst), N (natural history of the cyst), R (recurrent cyst) and C (complication of the cyst).


CONCLUSIONS
Consideration is given to almost all aspects of classifying liver hydatid cysts. A new concept for classification is presented which can become the basis for further multi-institutional comparison of data.
