Tarlov cysts (TCs) consist of dilated nerve root sheaths filled with cerebrospinal fluid (CSF) and are most frequently found in the sacrum. It is estimated that 25% of detected TCs cause chronic pain and intestinal and urogenital symptoms due to compression of the sacral nerve root fibers inside the
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
Although most patients with intracranial hypotension typically present with headaches, the rest of the clinical spectrum is characteristically non-specific and often quite variable. In a patient with concurrent pathologies that can produce a similar clinical picture, a high index of suspicion must
BACKGROUND
Tarlov cysts (TC) are present in 4.6% of the population and represent a potential source of chronic pain. When present at lumbosacral levels, symptoms are classically described as perineal pain/pressure, radiculopathy, and headache. Treatment outlined to date primarily includes cyst
Tarlov cysts (TC) are commonly found spinal perineural cysts. Symptomatic TCs are rare, however, and there is no consensus on their pathogenesis and optimal management.To characterize cyst growth in patients with symptomatic The origin and pathogenesis of perineurial cysts remain unclear. Here, we report a rare case of multiple sacral perineurial cysts presented symptoms triggered by nonaneurysmal perimesencephalic subarachnoid hemorrhage (SAH). A 48-year-old male presented with a severe headache of sudden onset. Brain
While infrequent, cerebrospinal fluid (CSF) leaks are known to occur after surgical resection of vestibular schwannomas. Early signs of CSF leak often include headache and altered mental status. If untreated, life-threatening complications can occur, including brainstem herniation and meningitis.
Perineurial cysts usually affect the lumbosacral spinal nerve roots, but sometimes they can erode the sacrum and reach the retroperitoneal space. In such cases misdiagnosis can lead to an improper treatment and cause serious complications. A presacral mass was diagnosed in a young woman during
A 47-year-old woman with postural headache, episodic stupor, and vertical gaze palsy had brain imaging findings consistent with spontaneous intracranial hypotension (SIH), including severe descent of the mesodiencephalic structures and diffuse pachymeningeal enhancement. The source of the
A 56-year-old female with 2 prior Chiari decompressions presented with rapidly progressive cognitive decline. Brain magnetic resonance imaging, computed tomography myelogram, and prone digital subtraction myelography revealed signs of brain sag and left T9 perineural cysts but no cerebrospinal fluid
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
A 76-year-old woman was admitted to our hospital with complaints of a three-day history of severe postural headache without any apparent cause. Neurological examination revealed nuchal rigidity, and right auditory nerve paresis. Lumbar puncture yielded a low opening pressure of 50mmH2O and an
BACKGROUND
Anatomic variations of the superior sagittal sinus (SSS) and falx cerebri (FC) are uncommon in that agenesis of these structures is extremely rare. We report an extremely rare anatomic variation, total agenesis of the SSS and FC, and briefly discuss it from the anatomical, embryological,
The authors describe a technique for percutaneous endoscopic shunt placement to treat clinically symptomatic spinal cysts. Seven patients underwent the procedure--five with syringomyelia, one with a symptomatic perineurial cyst, and one with a large arachnoid cyst. In all patients the shunt was
