A rare case of caudal duplication

Area of Science:

• Medical Science
• Developmental Biology
• Clinical Case Reports

Background:

• Caudal duplication, a rare congenital anomaly, involves duplication of the lower half of the body.
• Parasitic twins, or conjoined twins where one twin is underdeveloped and dependent on the other, present unique diagnostic and management challenges.
• Omphalocele, a defect of the abdominal wall, is often associated with complex congenital anomalies.

Observation:

• A neonate presented with caudal duplication, exhibiting two well-formed lower limbs and a pelvis.
• External male genitalia were noted, attached to the epigastrium, indicating an unusual parasitic attachment site.
• The infant did not present with an omphalocele, distinguishing it from other reported cases.

Findings:

• This report details the second known instance of parasitic conjoined twin attachment at the epigastrium.
• It is the first documented case of caudal duplication occurring without an associated omphalocele.
• The successful surgical separation and outcomes are critical for understanding treatment protocols.

Implications:

• This case expands the understanding of the spectrum of caudal duplication anomalies and parasitic twin presentations.
• It highlights the importance of detailed imaging and diagnostic evaluation in complex congenital malformations.
• Further research into the embryological origins of such anomalies can inform future clinical management and genetic counseling.
