case_images: The clinical examination showed well-circumscribed brown stains of more than 5 mm on the trunk and limbs (Figure 1), and the rest of the clinical examination, in particular neurological, ophthalmological and ENT, was without particularities.
case_images: (A) Antero-medial incurvation of the tibia, angulation of the fibula with densification and cortical thickening reducing the medullary canal and solution of bony continuity associated with a callus, in relation to a congenital pseudarthrosis. (B) Respect for spinal statics, posterior scalloping more marked at the level of the vertebral body of L5.

case_images: An X-ray of the left lower limb was performed (Figure 2), followed by one of the spine (Figure 3).
case_images: Absence of vascular anomalies, bone signal anomaly with tibio-peroneal pseudarthrosis, absence of soft tissue proliferation.

case_images: fig3-2333794X221101771
case_images: An X-ray of the left lower limb was performed (Figure 2), followed by one of the spine (Figure 3). Additional MRI and bone marrow studies showed (Figures 3 and 4).
case_images: Multiplanar T2 MRI sections, T1 sag without gado, ax DWI, and T1 sag with injection showing dural ectasia with posterior scalloping of the vertebral bodies of L5 and S1. At the level of the lumbosacral vertebrae (L4, L5, and S1), presence of several right paraspinal serpiginous formations enlarging the homolateral foramen, with indistinct contours pushing back the right spinal muscles and the homolateral psoas of heterogeneous hyper T2 signal centered by a hypo signal zone, hypoT1 weakly enhanced after injection of gado in connection with plexiform neuromas.
