An 11-year-old female patient presented with congenital spinal deformity with a history of occasional pain in the right flank for a duration of six months. On evaluation, she was diagnosed to be a case of type III Klippel Feil syndrome (KFS) with crossed fused renal ectopia (left to right) and pelviureteric junction obstruction (PUJO) of the right moiety.
