Article Synopsis
  • Spinal intradural lipomas are rare tumors, particularly when not linked to spinal dysraphism, and are often diagnosed late due to their gradual growth and location.
  • A case involving an eight-year-old girl revealed a lipoma and a cyst in her lumbar region, leading to symptoms like limb weakness and urinary issues; both lesions were partially removed surgically with a successful recovery.
  • The discovery of fluid-filled cysts alongside lipomas is extremely rare, and while the exact origin of these lipomas is unclear, their coexistence with cysts may prompt earlier detection and intervention.

Intradural spinal lipomas are rare benign lesions typically located in the lumbosacral region and associated with spinal dysraphism in children. When unassociated with spinal dysraphism, they are most often diagnosed in young children or adolescents following the emergence of neurological symptoms. In their most rare form, intradural spinal lipomas may be found in adults without spinal dysraphism.

Objective: Intramedullary spinal cord lipomas without spinal dysraphism are rare. Although they are benign tumors, they can cause significant neurological deficits. Their tight adherence to the spinal cord presents a challenge for resection.

Introduction: Intramedullary nondysraphic spinal lipomas are extremely rare among primary spinal cord tumors. These patients present with nonspecific sensory symptoms followed by deterioration of motor symptoms. As the safety margins for neurological preservation are thin, meticulously locating the extent of the tumor and choosing the resection modalities is essential.
