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

Table 2 Comparison of our case to other reports in the literature with regard to orthopaedic sequelae described and follow-up emphasis

Ref.	Main focus	Orthopaedic sequelae described	Follow-up emphasis	Why our case adds value
Kumar et al[14], 2014	Nerve-territory undergrowth in sciatic/lumbosacral NMC	Yes: Limb shortening and hip dysplasia	Mechanistic association and phenotype description	Our case extends this by detailing longitudinal surveillance, orthopaedic decision-making and timing of guided growth intervention
Park[9], 2019	Long-term natural history of sciatic NMC	Orthopaedic issues not the primary focus	Neurological and radiological stability over long follow-up	Our case complements this by showing that prolonged lesion stability may coexist with progressive orthopaedic burden requiring treatment
Present case	Longitudinal paediatric multidisciplinary management	Yes: Limb length discrepancy, pelvic obliquity, scoliosis, achilles contracture, calcaneal deformity	Orthopaedic surveillance and post-biopsy conservative nerve management	Distinguishing contribution is the detailed orthopaedic pathway from observation to guided growth planning and intervention near skeletal maturity

NMC: Neuromuscular choristoma.
