Two rare teratomas with limb-like structures, one cervical and one lumbosacral, were surgically treated. These cases highlight the importance of surgical intervention for spinal cord protection in these complex congenital anomalies.

Area of Science:

  • Developmental biology
  • Neuroscience
  • Surgical oncology

Background:

  • Teratomas are congenital tumors containing various tissue types.
  • Paraspinous and occipital teratomas with extremity development are exceptionally rare.
  • Intradural extension poses risks for spinal cord function.

Observation:

  • Presentation of two unique cases: a posterior cervical teratoma resembling digits and a lumbosacral teratoma with limb-like features.
  • These represent the seventh and eighth reported instances of paraspinous or occipital teratomas with recognizable extremity development.
  • Both presented anomalies exhibited intradural extension, necessitating surgical evaluation.

Findings:

  • Surgical exploration was required to address the intradural component of both teratomas.

  • The primary goal of surgery was to mitigate the risk of future spinal cord tethering.
  • Detailed preoperative assessment, surgical techniques, and postoperative outcomes were documented.

    • Implications:

    • Early surgical intervention is crucial for managing teratomas with intradural extension.
    • Understanding these rare anomalies aids in predicting and preventing neurological complications.
    • This report contributes valuable data to the literature on spinal teratomas and congenital limb malformations.
