A case of lung adenocarcinoma developing chylothorax after transthoracic Tru-cut biopsy.

Chylothoraces are mostly secondary to trauma and tumors, and rarely idiopathic. Chylothoraces secondary to lung tumors are mostly seen postoperatively. In this article, we, for the first time, present massive chylothorax developing after diagnostic transthoracic Tru-cut biopsy in a lung adenocarcinoma case. The patient was successfully treated with drainage and octreotide. In conclusion, it should be kept in mind that chylothorax can be also seen as a complication after interventional biopsy procedures; therefore, the patients should be followed carefully.
