3-year-old female with noisy breathing and exertional dyspnoea with suspected mediastinal mass. (a) Plain radiograph shows mediastinal widening (white arrows) with relative narrowing at cardiac pedicle. (b) Coronal CT image shows tracheal narrowing by the homogeneous mass (black arrow). (c) Axial CT image demonstrates slit-like configuration of trachea (black arrow) due to compression. Blood vessels are widely separated (open arrows). (d) Sagittal CT image shows homogeneous anterior mediastinal mass (star) and relative narrowing of trachea (black arrow).

Chest radiograph showed wide superior mediastinum with a constriction at the level of cardiac pedicle [Figure 1a]. MDCT evaluation confirmed the presence of a homogeneous, non-enhancing anterior mediastinal mass (MM) separating the mediastinal arteries, compressing and laterally displacing the superior vena cava [Figure 1b-d].

Patient underwent surgery and near-complete removal of the tumor was achieved [Figure 3].
3-year-old female with noisy breathing and exertional dyspnoea with suspected mediastinal mass. Histological examination of the specimen; Photomicrograph with the hematoxylin and eosin stained tissue (a) at magnification of x100 shows hypocellular tumor (circle) consisting of bland spindle cells, (b) at magnification of x20 shows tumor adherent to thymic tissue (black arrow).

Microscopy showed a hypocellular lesion composed of bland spindle cells with scanty pale amphophilic cytoplasm, in collagenous stroma [Figure 4].
