Reveal Findings

CR – Abdominal radiograph shows an accessory tubular bone in the left gluteal region.

MR – Axial T1 and sagittal T2 images of the pelvis show a rudimentary extremity bone emanating from the left hemipelvis.

CR – Specimen radiograph showing accessory limb comprised of a rudimentary tibia and complete foot.

Reveal Discussion

Limb formation begins at the end of the fourth week of development with the lower limbs slightly later than the upper limbs. The apical ectodermal ridge induces subjacent medodermal differentiation of musculoskeletal tissues. Defective induction may result in absence, hypoplasia or duplication of a limb.

Reveal Diagnosis

Limb Duplication Anomaly
