C, symmetrical erythematous macules on the lower limbs in connection with erythema nodosum, left facial paralysis and bilateral sequelae of anterior uveitis on ophthalmologic examination. Chest X-ray showed bilateral mediastinopulmonary opacities associated with diffuse micronodular infiltration (Figure 1).
(A, B) chest CT axial section (medial and parenchymal window) bilateral and symmetrical non-compressive medial and para hilar adenopathy masses; bilateral para hilar peribronchovascular thickening; nodular thickening of the septal lines.

CT scan showed a magma of bilateral and symmetrical non-compressive medial and para hilar adenopathies, the largest of which measured 60 mm (right para hilar); bilateral para hilar peribronchovascular thickening; nodular thickening of the septal lines, with a pearly appearance of the scissures, more marked at the upper level; bilateral confluent basal sparse micronodules producing the sign of Galaxie (Figure 2). Cervical ultrasonography showed parotitis with swollen, hyper echogenic and heterogeneous glands with thick septa.
