Spine evaluation in children with anorectal malformations

Area of Science:

• Pediatric Radiology
• Medical Imaging
• Congenital Abnormalities

Background:

• Anorectal malformations (ARMs) are associated with a high incidence of spinal abnormalities.
• Early detection of skeletal and intraspinal pathology is crucial for managing infants with ARMs.
• The comparative diagnostic value of radiography, ultrasound, and MRI for spinal assessment in this population requires clarification.

Purpose of the Study:

• To evaluate the efficacy of radiography, ultrasound, and magnetic resonance imaging (MRI) in identifying skeletal and intraspinal pathologies in infants with ARMs.
• To determine the necessity of spinal MRI for infants diagnosed with anorectal malformations.

Main Methods:

• Retrospective analysis of 21 infants with anorectal malformations.
• All infants underwent lower spine examination using radiography, ultrasound, and MRI.
• Comparative assessment of the detection rates for skeletal and intraspinal abnormalities across the three imaging modalities.

Main Results:

• Radiography identified subtle bony skeletal abnormalities in 6 out of 21 patients.
• Ultrasound detected both bony and cartilaginous malformations in all 6 affected patients; MRI identified them in 5.
• Intraspinal pathology was present in 5 of the 6 patients with skeletal abnormalities, detected by both ultrasound and MRI, with MRI providing clearer visualization.

Conclusions:

• Careful examination of spinal radiographs is essential as they can indicate potential intraspinal pathology.
• Normal findings on radiography and ultrasound may render MRI unnecessary for spinal assessment in infants with ARMs.
• MRI is valuable for accurately depicting intraspinal pathology when radiography or ultrasound results are abnormal.
