Cavitation of Lung Metastases from Bladder Cancer. Report of two Cases

We describe 2 cases of cavitary lung metastasis from bladder cancer and retrospectively analyze the frequency of such an event in our environment. Although rare, this finding is not exceptional and should be taken into account when clinicians and oncologists face the differential diagnosis of pulmonary cavitation. Moreover, a cavitary pulmonary nodule may also be the presenting sign of bladder cancer.
