Introduction: A caudal appendix is a rare congenital malformation of the median or paramedian diverticulum type
located mainly in the lumbosacral region, of soft consistency, exceptionally provided with an axial skeleton and
covered with skin often of normal appearance and simulating a tail.
Patients: We report the cases of three female patients including two infants aged 4 months and 12 months and an
adult aged 35 years. The infants presented caudal appendages located at the atypical breech surface associated
with a right cephalocele and the adults had a caudal appendage 11 cm long located at the lumbosacral level 2 cm
from the midline on the right. Clinical examination noted one lesion in the first infant and three caudal appendages
in the second. The neurological examination was normal. The adult patient did not present any associated clinical
malformation. The CT scan noted cranial dysraphism in the form of intra-orbital meningocele associated with
shizencephaly for both infants.
Conclusion: Caudal appendages are rare and represent markers of dysraphism, which can be cranial or caudal.
Their presence requires systematic research through medical imaging examinations.
