Post Blalock-Taussig shunt mediastinal mass – a single shadow with two different destinies

One of the rare complications following BT shunt surgery is seroma formation. It usually is benign and x ray chest will reveal a mediatinal mass (left upper). CT scan usually confirms the diagnosis. Usually managed conservatively.
Axial contrast chest CT obtained in a helical mode. The sagittal oblique maximal intensity projection image shows a small hypodense lesion of fluid attenuation seen adjacent to the BT shunt. No calcification, enhancement, septae, air foci or solid component was seen. Features are consistent with a post operative seroma. Thin long arrow points BT shunt. Broader, short arrow points seroma
