ABSTRACT

• We would like to present two cases of caudal regression syndrome with different imaging findings, that is group one and two.

• Caudal regression syndrome, first described by Duhamel et al, is a rare entity with incidence of 1 to 5 cases in 100,000 births.

• This is characterized by abnormal development of the caudal spine of the developing fetus, which ranges from absent coccyx to sacral or lumbar agenesis. Syndrome is commonly associated with other orthopedic, genitourinary, gastrointestinal and cardiac anomalies. Imaging findings vary with the severity of the anomaly.

• Prognosis of this entity depends on the severity of disease and the presence of associated anomalies. Early diagnosis and surgical correction is imperative to decrease the risk of incontinence, recurrent urinary infections, renal derangement, and the development of a neuropathic bladder.

• Hence radiological investigations especially magnetic resonance imaging, play very important role in thorough evaluation of the spine, spinal cord and other associated anomalies.

• In this poster, we present two classical types of caudal regression syndrome showing spectrum of imaging findings.
