Gall bladder carcinoma presenting as multiple cavitary pulmonary metastases - a rare event.

Carcinoma of the gall bladder is the commonest malignancy of the biliary tract. It is either detected incidentally during routine imaging or presents as lump in right hypochondrium or with signs of jaundice. Rarely, it may present with multiple cavitary metastatic lesions in the pulmonary parenchyma. The authors, report such a rare case of gall bladder carcinoma that presented with extensive, bilateral pulmonary cavitary metastases with no evidence of any nodal disease and where the diagnosis was delayed due to this rare presentation.
