Diagnostic tools for evaluation of thoracic tumours and pseudotumours. We included in the differential diagnosis:

Paraffinoma (1), a hydatid cyst (1), inflammatory pseudotumour (3), nodular tuberculosis (2) and sarcoidosis granulomas (1), round pneumonia (1), nodular criptococosis (1), post-surgical or tuberculosis scarring processes (2), organising cryptogenetic pneumonia (2) and round atelectasis (3).


There are several diseases that can mimic tumours of the chest. It is necessary to take them into account and know how to use diagnostic keys for an accurate diagnosis.
