Abstract
Cavitary lung lesions are quite common findings on chest imaging and often pose a diagnostic challenge to the clinicians. We describe a case of a 75-year-old male who presented to the emergency room with hemoptysis. Computed tomography of the chest demonstrated multiple cavitary pulmonary nodules with peripheral groundglass opacities. Bronchoscopy did not reveal any active bleeding source, and washings were negative for malignancy and infectious cause. Computed Tomography guided biopsy of the left lung nodule showed metastatic carcinoma consistent with papillary renal cell carcinoma. This case highlights the unusual presentation of metastatic renal cell carcinoma.

Computed Tomography l guided biopsy of the left lung nodule showed metastatic carcinoma consistent ia with papillary renal cell carcinoma. This c case highlights the unusual presentation of r metastatic renal cell carcinoma. me Introduction m A pulmonary cavitary lesion is defined pathologically as a vacuolated lesion with o gas/air
The washings were negative for malignancy and infectious causes which further prompted a Computed Tomography guided biopsy of the left lung nodule, which showed metastatic carcinoma consistent with papillary renal cell carcinoma (RCC)
Cavitary lesions can n be a complication of septic emboli as a result of the thrombosis of pulmonary veso sels by microorganisms.[5] e cavitary lung lesions are most s commonly due to an infectious process, the possibility of a metastatic sequela in the setu ting of a pre-existing malignancy cannot be l undermined
Summary
Computed Tomography l guided biopsy of the left lung nodule showed metastatic carcinoma consistent ia with papillary renal cell carcinoma. This c case highlights the unusual presentation of r metastatic renal cell carcinoma.
