Fig. 2 — A 14-year-old male patient with Ewing’s sarcoma and aspergillosis. Pulmonary nodule (axial average diameter of 4 mm) in the right middle lobe was detected on CT and on all T1-weighted MR sequences (discontinuous arrows). The aspergillosis infection presented as ground-glass opacity with some nodular pattern in the left lower lobe (continuous arrow). The pathology was diagnosed on chest CT (a). With the incoherent GRE (b) and the volume interpolated GRE sequence (c), the infection was not detected during the initial analysis as it was misinterpreted as hypostasis and artefacts (continuous arrows). However, the ground-glass opacity was observed in the second-look sessions of both sequences in comparison with CT. In the UTE image (d), the pathology was correctly diagnosed during the initial evaluation session (continuous arrow)
