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.
Highlights
Midline Spinal Cord Hamartomas are relatively rare & asymptomatic than the common congenital spinal masses which include lipomas, epidermoid cysts, dermoid cysts, and teratomas [1]

Summary
Midline Spinal Cord Hamartomas are relatively rare & asymptomatic than the common congenital spinal masses which include lipomas, epidermoid cysts, dermoid cysts, and teratomas [1]. Midline Spinal Cord Hamartomas are not related to brain malformations or neurofibromatosis, and most patients have few or no neurological symptoms related to them [2]. These lesions may present with a tethered cord & a normal overlying skin, a skin dimple, a dermal sinus tract, cutaneous angioma or dense collagen [3]. These are composed of only ectodermal and mesodermal, mature and well-differentiated elements, meningothelial cells, calcification, and even urothelium [2,3]. We report 6 cases of Spinal Cord Hamartomas with tethered cord
