Rare malformations associated with partial anomalous pulmonary venous return: a cadaveric case report

Area of Science:

• Anatomy
• Developmental Biology
• Medical Genetics

Background:

• Anatomical dissections are crucial for understanding human variations.
• Rare congenital malformations require detailed documentation and analysis.
• Investigating complex anomalies aids in understanding embryological development.

Observation:

• A female Caucasian cadaver presented with multiple rare congenital malformations.
• Partial anomalous pulmonary venous return involved the left superior pulmonary vein connecting to the left brachiocephalic vein, creating a left-to-right shunt.
• Additional anomalies included an annular pancreas and a persistent umbilical vein connected to the portal vein system.

Findings:

• The pulmonary anomaly, partial anomalous pulmonary venous return, was characterized by an aberrant left superior pulmonary vein.
• An annular pancreas was present without causing duodenal obstruction.
• A persistent umbilical vein was observed, connecting to the left ramus of the portal vein.

Implications:

• This unique constellation of malformations provides a rare case study for embryological development.
• Understanding the genetic and developmental basis of these combined anomalies is essential.
• Further research can elucidate the etiology of such complex congenital conditions.
