Magnetic resonance imaging (MRI) of the spine showed thickening of the spinal cord, with hyperintense and diffuse edematous lesions extending from C4 to the cone, with heterogeneous contrast (Fig. 1 ).
Magnetic resonance imaging of the brain: FLAIR sequence shows demyelinating lesion.

MRI of the brain revealed demyelinating lesions in the right capsulo-thalamic, right temporal (Fig. 2 ), and left cortico-subcortical paramedian hemi-cerebellar white matter, which was enhanced after gadolinium injection. MRI of the lung showed a pulmonary infiltrate (Fig. 3 ).
Computed tomography of the chest revealed bilateral pulmonary infiltrates and nodules with a halo sign.

A few days later, the patient developed diffuse dermatologic manifestations, including palpable purpura and maculopapular exanthema (Fig. 4 ).
Repeated computed tomography of the chest shows reduction in the size of pulmonary nodules and infiltrates.

A clear reduction in pulmonary nodule size, micro- nodules, and infiltrates on chest CT (Fig. 5 ) was also observed.
