Ipsilateral decubitus position for percutaneous CT-guided adrenal biopsy.
Positioning the patient on the side to be biopsied elevates and relatively immobilizes the diaphragmatic leaf on the dependent side, allowing percutaneous adrenal needle biopsy by a direct posterior approach without traversing lung tissue. The ipsilateral decubitus position was used successfully for biopsy of four small adrenal lesions in which lung precluded a direct posterior approach in the prone position. In addition, the relative stability of the diaphragmatic leaf further facilitated accurate needle placement.
