Ectopic and heterotopic both refer to cells displaced from their normal site – ectopic cells occur outside their organ of origin whereas heterotopic cells are in an aberrant location within their organ of origin. The most common localization of heterotopic neuroglial tissue (HNT) is the nasal region. We report a case of 69-years-old man who presented with long history of lumbosacral pain with paresis of the inferior limb. MRI examination detected a cystic tumour located at the L1-L2 level. Histologic examination revealed the presence of heterotopic neuroglial tissue, containing synaptophysin, glial cells and encircled meninges.
