Lipomyelocele with osseous dysraphic hamartoma in a child: a case report.

Lipomyelocele is a well-known vertebral malformation that affects intraspinal and extraspinal tissues and compartments. However, other tissues can be associated with the lipomatous component, such as well-developed bones in unusual sites. This association is consistent with dysraphic hamartoma, one of the rarest malformations of the vertebral canal closure. We describe an 8-year-old girl without neurological deficit with a voluminous lipomyelocele associated with a well-developed flat bone articulated to the left iliac wing. We reviewed the role of magnetic resonance and computed tomography with tridimensional reconstruction in this rare form of spinal dysraphism and described the imaging features.
