What is a meningeal cyst?
Meningeal cysts are fluid collections lined with arachnoid that herniate through the dura (diverticula) or within the dura. Most of these are diverticula with communication to the subarachnoid space rather than true cysts and can result in cord compression and myelopathy as well as radiculopathy.
What causes cysts on sacrum?
The exact cause of Tarlov cysts is unknown. Several theories exist including that the cysts result from an inflammatory process within the nerve root sheath or that trauma injures the nerve root sheath and causes leaking of cerebrospinal fluid (CSF) into the area where a cyst forms.
Can the sacrum be removed?
Sacroiliac joint is mainly composed of the iliac and sacral 1-2; the sacral 3 and below sacrum are called lower sacrum; complete resection of S1-2 needs complete amputation of the sacroiliac joint and thorough reconstruction of the spine-pelvic connection; the surgery is difficult and is difficult to spread; while …
What problems can Tarlov cysts cause?
In some instances Tarlov cysts can cause nerve pain and other pain, weakness, or nerve root compression. Acute and chronic pain may require changes in lifestyle. If left untreated, nerve root compression can cause permanent neurological damage.
Are sacral tumors rare?
Sacral chordomas are rare, slow-growing tumours that are amenable to surgery, but unfortunately often diagnosed late. The aim of the study was to identify presenting symptoms, which may aid diagnosis and reduce the treatment time. Forty-four patients were identified with sacral chordoma between 1989 and 2006.
What type of doctor treats Tarlov cysts?
Most primary care physicians would not consider the possibility of Tarlov cyst. It is best to consult a neurosurgeon with experience in treating this condition. Tarlov cysts may be discovered when patients with low back pain or sciatica have a magnetic resonance imaging (MRI) performed.
What kind of doctor treats Tarlov cysts?
Do sacral meningeal cysts have a check valve mechanism?
The presence or absence of a check-valve mechanism is very important in determining the need for surgical intervention for sacral meningeal cysts. The presence or absence of a check-valve mechanism is very important in determining the need for surgical intervention for sacral meningeal cysts.
What are spinal meningeal cysts?
The cysts contain CSF and have thin walls. They may be intradural or extradural and may contain neural tissue. The spinal meningeal cyst classification uses these features to separate the different type of cysts. They have been occasionally associated with patient’s with connective tissue disorders such as :
What is a meningeal cyst or diverticulum?
David J. Dabbs MD, in Diagnostic Immunohistochemistry, 2019 A cyst located in the posterior or lateral epidural space in the spinal canal lined only by fibrous tissue that resembles dura and lacks arachnoid membrane is a meningeal cyst or diverticulum (seeTable 20.14 ).
Which MR findings are characteristic of intradural meningeal cysts?
Sagittal T2WI MR depicts an intradural dorsal meningeal cyst causing mild spinal cord compression. The cyst margins can be visualized adjacent to areas of turbulent CSF flow. This is a typical case of an intradural meningeal cyst presenting with myelopathy.
