Abstract
A human tail is a rare congenital anomaly with a prominent lesion in the lumbosacrococcygeal region. True tail does not have any underlying spinal abnormalities, whereas pseudo tails are associated with spinal abnormalities. It requires radiological investigation to differentiate between two and treat accordingly. Long term follow-up is required in case of pseudo tail to assess neurological development. Only few cases have been reported in English literature of vestigial tail with spina bifida. Here we report a case of vestigial tail with spina bifida in a newborn born to a mother with gestational diabetes mellitus.
Highlights
Histopathology of the globular mass specimen showed stroma consisting of lobules of adipocytes with pilosebaceous unit, congested blood vessels, nerve bundles, bone marrow with trabecular bones, glial tissue, skeletal muscle fibers
A true tail is a remnant of embryonic tail [3] and not associated with any underlying malformations.[4]
Caudal appendages occurring with spina bifida occulta or spinal dysraphism are pseudotails [2] as seen in our case
