What is anterior sacral meningocele?
Anterior sacral meningocele is a congenital anomaly characterized by agenesis of a part of the anterior portion of the sacrum, herniation of meninges through the defect, and formation of a hernial sac in the pelvis.
What is a sacral meningocele?
Introduction. Anterior sacral meningocele (ASM) is an anomaly where the meninges protrude into retroperitoneal and presacral space through an anterior sacral defect. Most of the cases present in adult age and diagnosis in childhood is rare. Common presentations include infection, meningitis and obstetric problems.
What causes Meningocele?
Meningocele results from a failure to develop the caudal end of the neural tube resulting in a protrusion that contains cerebrospinal fluid, meninges, overlying skin, and does not have the spinal cord as its content. Anterior meningocele is usually presacral in location.
Is Meningocele a cyst?
Intrasacral meningoceles are rare cystic lesions that can cause focal compression in the bony sacral canal. They are intrathecal cystic formations arising as protrusions of the arachnoid through a congenitally weak place in the dura mater.
What is a sacral meningeal cyst?
Sacral extradural spinal meningeal cysts (SESMCs) are extradural meningeal cysts located in the sacral canal. These cysts are commonly an incidental finding on magnetic resonance imaging (MRI), and are usually asymptomatic.
What is the treatment for meningocele?
Treating the meningocele involves closing the overlying meninges and the skin. Surgery is performed within a day or two of birth, and is necessary to prevent infection and to protect the exposed area of the spine.
How is meningocele diagnosed?
Diagnosing Meningocele A doctor may make the diagnosis through: Ultrasound. Amniocentesis. Alpha-fetoprotein (AFP) screenings in the second trimester.
What is the difference between meningocele and spina bifida?
Myelomeningocele (MMC), also known as meningomyelocele, is the type of spina bifida that often results in the most severe complications and affects the meninges and nerves. In individuals with myelomeningocele, the unfused portion of the spinal column allows the spinal cord to protrude through an opening.
Can meningocele cause hydrocephalus?
Hydrocephalus is one of the most commonly associated conditions with myelomeningocele, as is a condition called Chiari II malformation, or hindbrain herniation.
What are 5 Health issues a person with spina bifida might have?
The person might have back pain, scoliosis (crooked spine), leg and foot weakness, changes in bladder or bowel control, and other problems. A tethered spinal cord can be treated with surgery.
What is the most serious complication of spina bifida?
Myelomeningocele is a severe type of spina bifida in which the membranes and the spinal nerves protrude at birth, forming a sac on the baby’s back. The exposed nervous system may become infected, so prompt surgery is needed after birth.
What is anterior meningocele?
Anterior meningocele is characterized by herniation of CSF-filled sac through a an anterior osseous defect. It usually occur in sacral region where is it termed an anterior sacral meningocele although it can also in other areas like the thorax 2 .
How many anterior sacral meningocele have been recorded so far?
They bring to at least 52 the examples of anterior sacral meningocele so far recorded. Anterior sacral meningocele is a congenital anomaly characterized by agenesis of a part of the anterior portion of the sacrum, herniation of meninges through the defect, and formation of a hernial sac in the pelvis.
What is an anterior sacral meningeal cyst?
Anterior sacral meningocele is a congenital defect seen in the anterior aspect of the spine. It is defined as a meningeal cyst that occurs in the presacral space secondary to agenesis of a portion of the anterior sacrum.
Which physical findings are characteristic of congenital anterior sacral meningocele?
The most consistent physical finding in congenital anterior sacral meningocele is a soft, cystic, retrorectal mass that appears fixed to the sacrum. 12,13 The mass is felt most commonly on rectal examination but may be felt on pelvic, abdominal, gluteal, or inguinal examination as well.
