Coronal C+ arterial phase
A planning CT is performed prior to transcutaneous biopsy of the mass. Due to the proximity of the mass to the aorta, despite the patients borderline renal function, a contrast bolus is administered. Contrast CT obtained for biopsy planning (see grid on anterior chest) demonstrates the mass to be a false aneurysm of the aorta rather than a pulmonary mass. Needless to say not biopsy was performed.
