Caudal cell mass developmental aberrations: an imaging approach.

Area of Science:

• Embryology
• Radiology
• Pediatric Surgery

Background:

• The caudal cell mass, a primitive streak remnant, forms the lower spinal cord, filum terminale, and nerve roots.
• Anomalies arise from abnormal caudal cell mass development, leading to conditions like tight filum terminale and sacrococcygeal teratoma.
• These anomalies often coexist with gastrointestinal and genitourinary malformations due to simultaneous development.

Purpose of the Study:

• To outline antenatal and postnatal imaging criteria for diagnosing caudal cell mass developmental anomalies.
• To establish imaging's role in workup, prognostication, and guiding treatment interventions.
• To provide an overview of associated multisystem abnormalities diagnosed via antenatal imaging.

Main Methods:

• Review of embryology of the caudal cell mass.
• Description of antenatal and postnatal imaging findings.
• Discussion of clinical manifestations and treatment strategies.

Main Results:

• Specific imaging criteria for diagnosing various caudal cell mass anomalies are presented.
• Imaging aids in staging, prognostication, and planning interventions.
• Associated anomalies in other systems are highlighted where applicable.

Conclusions:

• Antenatal and postnatal imaging are crucial for diagnosing and managing caudal cell mass anomalies.
• Accurate imaging facilitates prognostication and guides appropriate treatment.
• Understanding embryology and imaging findings is key for comprehensive patient care.
