Abstract

Midline Spinal Cord Hamartomas are relatively rare and asymptomatic. These lesions may present with a tethered cord and a normal overlying skin, a skin dimple, a dermal sinus tract or dense collagen. Most patients have few or no neurological symptoms related to them. Microscopically they are composed of mature and well-differentiated ectodermal and mesodermal elements, meningothelial cells, calcification, and even urothelium. We report MRI and histologic features of midline spinal cord hamartomas in six cases.
