Benign but not inconsequential, paediatric sciatic nerve neuromuscular choristoma and its longitudinal impact: A case report

Figure 1 T2-weighted magnetic resonance imaging of the lumbosacral region (August 2024) demonstrating nerve root enlargement due to neuromuscular choristoma. A: Expansion of the left L4–S2 nerve roots through the pelvis, indicated by arrowheads; B: Axial magnetic resonance imaging view at the level of the sciatic nerve, illustrating markedly hypertrophic left sciatic nerve fascicles (encircled) on the left side. These images confirm the findings of sciatic nerve neuromuscular choristoma without evidence of a discrete mass or malignant change.
