Caudal regression syndrome with sacral rib: MRI features.

Area of Science:

• Medical imaging and diagnostics
• Pediatric neurology
• Congenital anomalies

Background:

• Caudal regression syndrome (CRS) is a spectrum of developmental abnormalities affecting the lower spine and limbs.
• Sacral ribs are exceptionally rare anatomical variations, with limited documentation in medical literature.

Observation:

• A 3-year-old female presented with urinary/bowel incontinence and gait disturbances.
• Magnetic Resonance Imaging (MRI) revealed a left-sided sacral rib, terminal cord syrinx, and caudal regression syndrome affecting sacrococcygeal segments.

Findings:

• The case demonstrates a unique combination of sacral rib, terminal cord syrinx, and caudal regression syndrome.
• This specific association has not been extensively reported, underscoring its rarity.

Implications:

• Further investigation into the embryological mechanisms linking sacral ribs and CRS is warranted.
• Understanding this rare association may improve diagnostic accuracy and patient management for complex spinal anomalies.
