[A rare case of caudal appendage].

Area of Science:

• Medical Genetics
• Developmental Biology
• Pediatric Surgery

Background:

• Caudal appendages are rare congenital malformations, often presenting as a tail-like protuberance.
• These anomalies can be associated with underlying spinal dysraphism, necessitating thorough investigation.
• The differential diagnosis includes conditions like spina bifida, teratoma, and pilonidal sinus.

Observation:

• A case of a female infant with a prenatally diagnosed caudal appendage is presented.
• Further examination revealed an extension of the appendage to the spinal cord.
• The infant underwent surgical correction at two months of age.

Findings:

• Caudal appendage is a cutaneous marker for potential spinal dysraphism.
• Association with spinal dysraphism poses a risk for tethered cord syndrome.
• Tethered cord syndrome can lead to significant neurological complications if untreated.

Implications:

• Early detection and diagnosis of caudal appendages are crucial for identifying associated spinal abnormalities.
• Surgical intervention may be necessary to prevent or treat complications like tethered cord syndrome.
• Management strategies involve either surgical correction or expectant observation based on clinical findings.
