The thoracic computed tomography (CT) scan showed several bilateral nonspecific micronodules (Figure 1(a)), and the positron emission tomography computed tomography (PET-CT) scan showed moderately hypermetabolic retroperitoneal and inguinal lymphadenopathy. A sinus CT scan was performed and showed pansinusitis (Figure 1(b)).
Evolution of c-ANCA titers over time. CMA: cyclophosphamide and methylprednisolone-based treatment followed by azathioprine. MR: methylprednisolone and rituximab-based treatment. This figure represents the evolution of c-ANCA titers over time. Peaks correspond to episodes of clinical relapses, and the falls correspond to improvements after treatment.

fig2
The patient presented a good clinical evolution with normalisation of the inflammatory syndrome and a significant decrease in c-ANCA (Figure 2). There was an increased inflammatory syndrome as well as increased ANCA titers (variation of titers is shown in Figure 2).
