case_images: Cerebral MRI: (a) coronal view T1 with gadolinium injection: left cerebellar nodular lesion with central necrotic zone and peripheral contrast enhancement. (b) Coronal view T1 without gadolinium injection: periventricular localization of multiple cerebral hypersignal nodular lesions.

case_images: The MRI performed 3 days later detected diffuse periventricular cerebral and cerebellar contrast-enhanced lesions (hypersignal Flair) (Figure 1).
case_images: Cerebellar biopsy: (a) nodular granulomatous lesion with mononuclear cells (Hematein-eosin x 40). (b) Atypical cells with mitosis (*) (Hematein-eosin x 40). (c) Staining with anti-CD20 (x40): atypical cells are stained. (d) Staining with anti-EBV-LMP1 (x40): a lot of cells are stained.

case_images:  The histological study (Figure 2) showed a heterogeneous necrotising lesion, with cellular remnants, granulomatous clusters of giant cells, with circumvented nuclei and well visible nucleoli, which looked like lymphoplasmocyte cells.
case_images: Pulmonary localisation of lymphomatoid granulomatosis. Transverse CT view, with contrast injection in parenchymatous window showing nodular lesions taking contrast. (a) At initial diagnosis. (b) 2 years after reduction in the immunosuppression and rutiximab therapy.

case_images: The CT scan of the thorax showed 6 pulmonary nodules of tissular density in the left lung and one pulmonary nodule in the right lung (Figure 3(a)). The thoracic CT scan showed only a single nodule (Figure 3(b)).
