Sacrococcygeal Agenesis with Sacral Lipoma in a Child of a Non-Diabetic Mother.

Sacrococcygeal agenesis or caudal regression syndrome is an uncommon disorder in which there is partial or total agenesis of the sacrum with or without lumbar involvement. Very few cases have been reported in the literature. We report a case of a 7-year-old child of a non-diabetic mother who presented with complaints of urinary and faecal incontinence since birth. Clinical examination revealed a soft, fluctuant swelling at the lower aspect of the back. The sacral and coccygeal bones were not palpable. CT scan and MRI confirmed sacrococcygeal agenesis with a sacral lipoma. He was being managed with pelvic floor training and physiotherapy with minimal improvement before being lost to follow up.
