Meningocele vs. Meningomyelocele: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Meningocele involves a sac of spinal fluid and meninges protruding through a spinal defect, while Meningomyelocele includes spinal cord/nerves in the sac.
Key Differences
Meningocele is a type of spinal defect where a sac containing spinal fluid and meninges (but not the spinal cord) protrudes through a gap in the vertebrae. Meningomyelocele, a more severe form, involves the protrusion of the spinal cord and/or nerve tissues within the sac.

In Meningocele, the protruding sac does not contain neural elements, making it generally less severe than Meningomyelocele, where the sac contains parts of the spinal cord and/or nerve tissue, leading to more significant potential neurological impairments.

Meningocele might not always present with significant symptoms initially and can be sometimes identified only through imaging, whereas Meningomyelocele typically presents with more noticeable neurological deficits at birth due to the involvement of spinal cord/nerves.

Surgical interventions for Meningocele primarily focus on repairing the protruding sac and preventing infection. In contrast, Meningomyelocele surgeries are more complex due to the involvement of the spinal cord and nerves, aiming to minimize nerve damage and manage associated conditions.

Meningocele’s impact on a patient’s mobility and neurological function is usually less severe compared to Meningomyelocele, where the risk of complications like paralysis or bladder and bowel dysfunction is higher.
