Results and follow up
We proceeded further with a chest CT angiogram, which revealed a
well-defined anterior mediastinal soft tissue density mass lesion
measuring about 84.9x67.2mm, seen at the aorto-pulmonary window. The
mass exhibited a mass effect, compressing the main pulmonary artery and
proximal ascending aorta. The mass showed a calcified wall with
enhancement after IV contrast, with two different densities within. The
mass showed close contact, almost inseparable from the ascending aorta.
A definite relation with the aorta could not be established, whether it
originated from or was invading it (Figure 5).
