A rare case of a 3-month-old infant with an extra third arm is presented. This congenital anomaly was linked to spinal cord abnormalities, prompting an examination of its origins.

Area of Science:

  • Medical Case Reports
  • Developmental Biology
  • Pediatric Surgery

Background:

  • Congenital anomalies present unique diagnostic and management challenges in pediatrics.
  • Understanding the embryological basis of rare malformations is crucial for clinical practice.

Observation:

  • A 3-month-old infant presented with a supernumerary third arm.
  • The accessory limb was located in the midcervical region.
  • Associated findings included posterior cervical dysraphism and a cervical cord lipoma.

Findings:

  • The case highlights a rare presentation of polymelia (supernumerary limb).
  • The association with spinal dysraphism suggests a potential shared developmental pathway.
  • Histopathological examination of the appendage was not detailed in the abstract.

Implications:

  • This case contributes to the literature on rare congenital limb malformations.
  • Further research into the genetic and environmental factors influencing limb development is warranted.
  • Such cases may inform surgical planning and genetic counseling for similar presentations.
