Air Embolus Complicating Transthoracic Percutaneous Needle Biopsy

Transthoracic percutaneous needle biopsy has become popular for evaluation of pulmonary nodules. However, it is a procedure with morbidity and mortality that is not negligible. In this article, we report massive air embolus complicating needle biopsy in a patient with amyloidosis. A negative biopsy does not exclude malignancy, and if surgical excision will be performed regardless of the result, preoperative assessment using this technique may not be necessary.
