Abstract:
:This description of procedures in two patients illustrates successful thoracic needle biopsy, despite the fact that the lesion was obscured by overlapping bones in each instance. The technique of screwing a 20-gauge needle through the overlapping bone is suggested as an innovative method when more traditional approaches to the lesion are not feasible.
