Area of Science:

  • Veterinary Medicine
  • Developmental Biology
  • Teratology

Background:

  • Cephalothoracopagus twins, a rare conjoined twin presentation, exhibit fusion of the head and thorax.
  • This condition is characterized by two separate spines, limbs, and pelves.
  • Understanding embryonic duplications is crucial for managing such rare congenital anomalies.

Observation:

  • A case of a female cephalothoracopagus conjoined twin kitten is described.
  • Gross examination revealed significant external and internal anatomical abnormalities.
  • Radiological imaging highlighted developmental defects in the head, spine, and thorax.

Findings:

  • The study documents the gross and radiological features of cephalothoracopagus conjoined twins in a feline.
  • Key findings include shared cephalothoracic structures with duplicated spines and pelves.

  • Developmental abnormalities were prominent in the head, spinal column, and thoracic region.

    • Implications:

    • This case contributes to the limited veterinary literature on cephalothoracopagus conjoined twins.
    • The findings underscore the importance of recognizing embryonic duplications in veterinary diagnostics.
    • Understanding the pathogenic mechanisms may aid in predicting and managing dystocia in affected animals.
