tarlov cysts/asthenia

BACKGROUND Tarlov cysts (TC) are focal dilations of arachnoid and dura mater of the spinal posterior nerve root sheath that appear as cystic lesions of the nerve roots typically in the lower spine, especially in the sacrum, which can cause radicular symptoms when they increase in size and compress

BACKGROUND Perineural cysts of the sacrum, or Tarlov cysts, are cerebrospinal fluid (CSF)-filled sacs that commonly occur at the intersection of the dorsal root ganglion and posterior nerve root in the lumbosacral spine. Although often asymptomatic, these cysts have the potential to produce

BACKGROUND It is now recognized that most, if not all, cases of spontaneous intracraneal hypotension result from spontaneous cerebrospinal fluid (CSF) leaks. The exact cause of spontaneous leak often remains unclear. However, two factors are typically considered: trivial trauma and weakness of the

Perineural (Tarlov) cysts are cerebrospinal fluid-containing perineural sacs that are usually located in the sacral spine. While often asymptomatic, they can cause progressive neurological symptoms including pain, paraesthesia and weakness. We present a case of a 24-year-old patient who had

Perineural cysts are believed to be asymptomatic; however, they rarely cause symptoms related to nerve root compression. Cervical symptomatic perineural cysts are in fact exceedingly rare. There are no reported cervical perineural cysts in the literature that present like cubital tunnel syndrome. A

We describe the rare simultaneous occurrence of epidural lipomatosis and a perineural cyst at the same level, lumbar kyphosis, osteoporotic vertebral fractures, and neurological deficits. A 75-year-old corticosteroid-dependent female farmer presented with severe low back pain, progressive lumbar

The primary aim of our study was to provide a comprehensive review of the clinical, imaging, and histopathological features of Tarlov cysts (TCs) and to report operative and nonoperative management strategies in patients with sacral TCs. A literature review was performed to identify articles that

OBJECTIVE Tarlov cyst is an abnormal expansion of the spinal nerve sleeve, and it communicates with the subarachnoid cavity via a perineural fistula. This study presents our experience of a balloon-assisted fistula sealing procedure in treating Tarlov cyst. METHODS Twenty-two patients with

Spontaneous spinal cerebrospinal fluid (CSF) leaks are increasingly recognized in patients presenting with orthostatic headache and ultimately diagnosed with intracranial hypotension. While the precise cause of these spontaneous leaks is unknown, it is thought to result from underlying weakness in

Sacral bone remodeling with abnormal dilatation of intervertebral foramina is usually associated with Tarlov's perineurial cysts but can also be caused by slow-growth lesions. In this case report, an atypical inflammatory sacral cyst with bone scalloping was found and some possible causes are

OBJECTIVE Intrasacral meningoceles are rare cystic lesions that can cause focal compression within the bony sacral canal. Their mechanisms are poorly understood, but most intrasacral meningoceles appear to be intrasacral extradural cysts caused by arachnoid herniating through a small dural defect in

Perineural Tarlov cysts located on lumbo-sacral roots can be a cause of cauda equina syndrome. OBJECTIVE 1) To draw attention to the fact that multiple Tarlov lumbo-sacral perineural cysts can produce serious movement disturbances. 2) To document the usefulness of the magnetic resonance imaging in
