Intradural spinal lipoma of the cervical cord

Cervical intradural extramedullary lipoma: A rare differential diagnosis of nontraumatic limping in an adult patient

“…Subsequent growth causes ventral flattening of the cord, separation of the posterior columns, and incorporation of the nerve roots. Thus, at surgery, they give the appearance of being intramedullary . It is very rare for these lipomas to be purely intramedullary, whereas others are part intramedullary and part extramedullary .…”

Long Term Outcome of Non-Dysraphic Intramedullary Spinal Cord Lipomas in Adults: Case Series and Review

“…Non-dysraphic intramedullary spinal cord lipomas are very rare, especially in adults [1,2,5,10]. Most of the reported cases in the literature are located in the cervico-dorsal region and occur in children [2,4,5,11,12,13,14,15,16,17,18]. Perhaps spinal cord intramedullary lipomas are best considered as congenital inclusion tumors of the central nervous system.…”

Congenital Intramedullary Lipoma of the Dorsocervical Spinal Cord with Intracranial Extension

“…A lack of cleavage plane and the intermingling of neural and fibrofatty tissue at the periphery of the tumor made total tumor removal impossible. The reported operative options include a simple posterior fossa decompression combined with cervicallaminectomy or a laminotomy with flap elevation (12) along with a biopsy (7), and partial (1,4,11,16) or subtotal removal (3,12). In very extensive lesions involving most of the spinal cord and brain stem, a two-stage procedure may be a reasonable option.…”

“…Her bladder and bowel control Extensive intramedullary lipomas of the cervicothoracic spinal cord, which extended into the brain stem, were not associated with spinal dysraphism, and presented in the infancy / neonatal period, are extremely rare and poorly documented. Most of the cases reported in the literature (1, 2, 5, 6, B), were confined to four or five segments of the cord (3), presented in adult life (1,3,5), and extended rarely into the posterior fossa and brain stem (16). Most of the reported intradural lipomas of the cord were subpial (3,7,9) and not truly intramedullary.…”

“…Of these five, only one was completely surrounded by spinal cord tissue. A few reports of cervical cord lipomas with an intracranial extension have appeared (11,12,16), but none pre- mously expanded cervicothoracic spinal canal filled by a large, low-density mass (-115 Hounsfield units) that extended intracranially through an enlarged foramen magnum. Figure 3 shows the lower pole of the lesion located in the center of the mid-dorsal cord.…”
