Intradural arachnoid cysts are a rare cause of spinal cord and nerve root compression. Primarily, they are present in the thoracic region posteriorly. We report a 25-year-old man who had an intradural arachnoid cyst at the level of conus medullaris presenting with cauda equina syndrome, which is very rare.

Arachnoid cysts cause a wide spectrum of clinical symptoms. Often it is difficult to clearly establish the relation between the presence of an arachnoid cyst and problems reported by the patient, which may, although not necessarily, be due to chronically elevated intracranial pressure. In recent years, increasing attention is paid to cognitive disorders accompanying arachnoid cysts, such as memory disorders, attention disorders, or language function disorders. This article presents a case of an 11-year-old patient, treated at the University Children's Hospital in Cracow for an arachnoid cyst, located in the left middle cranial fossa...

BACKGROUND: The etiology of abdominal pain is sometimes difficult to be defined. A presacral Tarlov cyst is an unusual cause of abdominal pain. The unusual location of a presacral Tarlov cyst can lead to misdiagnosis and inappropriate treatment. To guide the appropriate diagnosis and treatment, we review the cause, clinical presentations, radiological features and management options of this extremely rare lesion. METHODS: We performed an English-language literature search using Pubmed and internet searching to identify reports of patients with presacral Tarlov cysts...

Study Design: Retrospective case-control study. Purpose: To clarify the prevalence and risk factors for spinal subdural lesions (SSDLs) following lumbar spine surgery. Overview of Literature: Because SSDLs, including arachnoid cyst and subdural hematoma, that develop following spinal surgery are seldom symptomatic and require reoperation, there are few reports on these pathologies. No study has addressed the prevalence and risk factors for SSDLs following lumbar spine surgery...

Arachnoid cysts (ACs) are congenital malformations that may develop anywhere in the subarachnoid space along the cerebrospinal axis but are mostly observed in the temporal fossa and Sylvian fissure, predominantly in the left side. ACs account for 1% of all intracranial space-occupying lesions. ACs are a potential risk factor for subdural haematoma in all age groups following a traumatic head injury. Although an intracystic haemorrhage of AC without evidence of a head trauma is very rare, it may particularly develop in children and young adults who spend much more time engaged in games and forced physical exercise...

Vago-glossopharyngeal neuralgia (VGPN) is a rarely seen disease when compared to trigeminal neuralgia. When the pain is resistant to medical therapy, microvascular decompression can be performed if a vascular conflict is suspected on magnetic resonance imaging (MRI). In addition, arachnoid pathology may play a role in VGPN. We report two cases of VGPN caused by tethered arachnoid, associated with a vascular contact in which pain was reduced by freeing rootlets from arachnoid compression. We report two cases relating to 50-year-old and 30-year-old men with a history of electric shooting pain triggered by swallowing in the right pharyngeal and auricular regions...

This work makes proposals on the relationship between intracranial pressure (ICP) and hydrocephalus that changes over time with the evolution of the disease. This includes the cerebrospinal fluid (CSF) filling mechanism that leads to an increase in mode pressure if excess fluid volume exacerbates the obstructive process. Elevation in mode occurs because pressure in the central nervous system (CNS) represents a state of reduced flow, rather than an abnormality of volume. Diseases that cause elevated mode pressure by means of a primary edema can lead to hydrocephalus if there is sufficient time and obstruction to flow for the filling mechanism to act...

The purpose of this study was to perform an ophthalmological assessment in children with intracranial cysts and to assess the correlation between the occurrence of cysts and visual disorders. The documentation of 46 children with intracranial cysts, monitored by the Children's Outpatient Ophthalmology Clinic, Poznan, Poland was analysed. The best corrected visual acuity (BCVA), the alignment of the eyes, visual evoked potentials (VEP), comprehensive eye examination were performed in all patients. Additional ophthalmological tests were conducted to eliminate other causes of decreased visual acuity...

CASE REPORT: The authors report two cases of arachnoid cysts (ACs) neither detected during pregnancy nor shortly after birth when newborns underwent CT scan evaluation after birth head trauma. ACs were diagnosed at 10 months and 6 years, respectively. The first one becomes symptomatic, and the other one was incidentally found during a head trauma investigation. DISCUSSION: These cases give support for the postnatal pathogenesis for some of the assumed congenital ACs...

BACKGROUND: Spinal extradural arachnoid cysts (SEAC) are relatively uncommon. However, several large cysts have presented with spinal cord compression requiring surgical intervention. CASE DESCRIPTION: We report a patient with progressively enlarging SEAC causing worsening right S1 radiculopathy and gastrocnemius muscle atrophy. Electromyography (EMG) and nerve conduction studies (NCS) revealed an S1 motor radiculopathy. Serial magnetic resonance imaging (MRI) findings confirmed enlargement of the small cyst originating from the sacral thecal sac on the right while two smaller cyst on the left remained stable...

OBJECTIVE The pathophysiology underlying tonsillar herniation and CSF obstruction in Chiari malformation Type I (CM-I) is unclear, and the cause of CM-I-associated syringomyelia is not well understood. A better understanding of this pathophysiology is important for an improved treatment strategy. Therefore, the authors sought to identify, characterize, and examine the intradural pathology and CSF flow pathophysiology in the posterior fossa and at the level of the foramen magnum that occurs in the setting of CM-I...

Idiopathic spinal cord herniation is a rare and often missed cause of thoracic myelopathy. The clinical presentation and radiological appearance is inconsistent and commonly confused with a dorsal arachnoid cyst and often is a misdiagnosed entity. While ventral spinal cord herniation through a dural defect has been previously described, intravertebral herniation is a distinct entity and extremely rare. We present the case of a 70-year old man with idiopathic thoracic transdural intravertebral spinal cord herniation and discuss the clinico-radiological presentation, pathophysiology and operative management along with a review the literature of this unusual entity...

BACKGROUND: Intracranial prepontine cysts are rare and include epidermoid cysts, arachnoid cysts, and neurenteric cysts. Symptomatic prepontine cysts may require surgical intervention. Reports of spontaneous resolution of cysts are rare. CASE DESCRIPTION: We describe the case of a young gentleman who presented with headache and fever. Magnetic resonance imaging of the brain identified a prepontine lesion with features consistent with epidermoid cyst. During admission, the patient received symptomatic management in addition to empirical antibiotic therapy and dexamethasone...
