case_images: On examination, the swelling was soft-to-firm, nontender, midline in location, which started increasing in size at puberty and progressed since then to the present size of 14 cm x 12 cm [Figure 1].
case_images: (a and b) 3D Computed Tomography (CT) scan of the dorsal spine showing a wide bony defect in the posterior spinal elements from D3 to D9 vertebrae. (c) Diastematomyelia is also seen

case_images: Two hemicords with a dorsal type lipomeningomyelocele was identified [Figure 4].
case_images: (a) Hematoxylin and eosin stained section (x40) showing normal skin with appendages (single arrow); Subepithelial tissue shows lactiferous duct (double arrow). (b) Hematoxylin and eosin stained section (x80) showing lactiferous duct with secretion inside (single arrow) along with terminal duct lobular units of breast (double arrow). (c and d) Hematoxylin and eosin stained section (x20 and x40 respectively) showing lipomatous component composed of sheets of mature adipocytes with adjacent dural fibroblasts
