The sacrococcyx and L4 and L5 vertebrae are entirely absent, accompanied by partial absence of the L3 vertebra, inferring caudal regression syndrome.
In addition, some associated abnormalities are evident consistent with left isomerism, including:
- agenesis of the dorsal pancreas
- polysplenia
- azygos continuation of the inferior vena cava
Mild dilatation of the left urinary drainage system is seen, and the urinary collecting system of the right kidney and the right ureter are duplicated.
The urinary bladder is overdistended.
The prostate gland is enlarged and contains multiple dense calcified foci. Calcification is also present in vas deferens.
