Outcome of utilizing real-time contrast medium to detect the fistulas in spinal epidural arachnoidcysts and treat with minimally invasive surgery. Spinal epidural arachnoidcysts (SEACs) are rare, non-neoplastic pathologies that can cause compressive myelopathy. Preoperative identification of the exact fistula location is crucial for minimally invasive management. This single-center
Positive outcome after endoscopic treatment of a symptomatic convexity arachnoidcyst in an elderly. Cerebral convexity arachnoidcysts (ACs) only represent around 10-14% of the cysts. Symptomatic ACs in the elderly are rare. We present a 66-year-old woman with headache and a focal epileptic seizure. Imaging revealed a left parietal AC. Conservative management chosen but the patient's
Effect of continuous drainage of cranial arachnoidcysts into the ventricular system by stereotactic placed catheters. Surgical treatment of intracranial arachnoidcysts (iACs) is challenging. Microsurgical resection, endoscopic fenestration and cysto-peritoneal shunting are the most frequently used methods, each implying their own drawbacks. Stereotactic-guided cysto-ventricular drainage has course through the iAC to allow drainage into the ventricular system. Clinical and radiological control was performed on outpatient basis after a mean follow-up of 2 (1-3) months. The overall mean follow-up was 32 months (6-59). The measurement of the cyst volume was conducted by the ABC/2-method. Six patients with symptomatic arachnoidcysts (4 f, 2 m) were treated between 2010 and 2016. The overall
Outcomes of neuroendoscopy for suprasellar arachnoidcysts: a single center experiences. Arachnoidcysts are extra parenchymal, intra-arachnoid fluid collections of unknown origin, similar in content to cerebrospinal fluid. Suprasellar arachnoidcysts are a rarer localization resulting from abnormalities of the Liliequist membrane or cystic dilatation of the interpeduncular cisterna. We aimed to contribute to the literature by presenting a series of suprasellar arachnoidcyst cases with endoscopic intervention and long-term results. This study analyzed radiographic data, clinical symptoms, surgical records, and videos of giant arachnoidcysts that underwent endoscopic surgery between 2013 and 2023. Cyst volumes and Evan's indexes were calculated both preoperatively and postoperatively. The patient
Embolization as adjunctive treatment to achieve complete cure of ruptured arachnoidcyst associated with chronic subdural hematoma. Chronic Subdural Hematoma (CSDH) is a rare but classical evolutive complication of arachnoidcysts (AC). Its management has rarely been evaluated to date. Several approaches have been proposed including conservative and surgical treatments. Endovascular treatment in such CSDH subtype remains poorly reported. We present here an original case of a 16 years-old-boy suffering from ruptured AC responsible for CSDH successfully treated with embolization. Endovascular approach may be considered in the treatment of CSDH related to arachnoidcyst rupture.
Ophthalmic manifestations of ruptured arachnoidcysts in children. Intracranial arachnoidcysts are relatively common in the pediatric population. Rarely, they rupture, leading to acute subdural fluid collections, which can cause a sudden increase in intracranial pressure. The purpose of this study was to characterize ophthalmic sequelae in a large cohort of these patients. The medical records of all children treated for ruptured arachnoidcysts who presented at a single tertiary pediatric hospital for initial assessment between 2009 and 2021 were reviewed retrospectively. Of 35 children treated for ruptured arachnoidcysts during the study period, 30 received ophthalmological examination. Papilledema was found in 57% of these children, abducens palsy in 20%, and retinal hemorrhages in 10
Multiomic analyses implicate a neurodevelopmental program in the pathogenesis of cerebral arachnoidcysts. Cerebral arachnoidcysts (ACs) are one of the most common and poorly understood types of developmental brain lesion. To begin to elucidate AC pathogenesis, we performed an integrated analysis of 617 patient-parent (trio) exomes, 152,898 human brain and mouse meningeal single-cell RNA
Spinal extradural arachnoidcysts: a rare entity and review of the literature. Spinal extradural arachnoidcysts (SEDC) are rare primary spinal lesions, accounting for less than 1% of all spinal epidural lesions. The literature contains only case reports of this pathology, and treatment remains controversial due to its rarity. Major reported SEDC cases are caused by leaking out of cerebrospinal . The extradural cyst was excised completely and the dural defect was repaired. After surgical decompression, neurological symptoms gradually recovered. The extradural arachnoidcyst is an uncommon entity. Preoperative imaging is one of the determining elements in orienting the therapeutic management of the SEDCs. The choice of the surgical technique must be the least invasive in order to avoid postoperative
Growing and symptomatic intracranial arachnoidcyst in an elderly patient: a case report and literature review. We report an elderly patient with a symptomatic and growing arachnoidcyst. Physician should be cautious in counseling asymptomatic arachnoidcyst patients, regardless of their age, and inform them of the possibility, although rare, of growth and symptom development even in their late
How to locate the fistula orifice of spinal extradural arachnoidcyst: Surgical experience and clinical outcome. In clinical practice, spinal extradural arachnoidcysts (SEAC) are relatively rare. The key to the treatment of SEAC is recognize and close the dural defects (fistula orifice), but there is currently no convenient method to locate and identify the fistula. We propose a method
Long-term outcomes following surgical treatment of spinal arachnoidcysts: a population-based consecutive cohort study. Spinal arachnoidcysts (SACs) are rare, cerebrospinal fluid-filled sacs lined by an arachnoid membrane in the spinal canal. Symptoms can develop due to pressure on the spinal cord or adjacent spinal nerves by the cyst itself or by interrupted flow of cerebrospinal fluid. If non
Does right hemisphere compensate for the left in school-age children with large left middle fossa arachnoidcysts? To assess the cognitive function changes and brain network neuroplasticity in school-age children having large (diameter > 5 cm) left middle fossa arachnoidcyst (MFACs). Eleven patients and 22 normal controls (NC) between 6 and 14 years of age were included. The CNS Vital Signs
Bilateral pediatric pial arteriovenous fistulas accompanying a giant arachnoidcyst with torticollis: A case report. Pial arteriovenous fistula (PAVF) occurs when intracranial arteries communicate directly with veins. PAVFs are very rare congenital vascular lesions that are commonly seen in infants and children. Arachnoidcysts are congenital cavitation often filled with cerebrospinal fluid. We present a very rare associated occurrence of bilateral pediatric PAVF and a giant arachnoidcyst presenting as torticollis in a child. So far, this is the first case. A 6-year-old male child was referred to our facility from a local hospital due to severe torticollis. An enhanced computed tomography scan revealed 2 slightly high-density masses at the anterior pontine cistern, right circumferential
Symptomatic hemiparkinsonism due to extensive middle and posterior fossa arachnoidcyst: case report. Intracranial neoplasms are an uncommon cause of symptomatic parkinsonism. We here report a patient with an extensive middle and posterior fossa arachnoidcyst presenting with parkinsonism that was treated by neurosurgical intervention. Retrospective chart review and clinical examination membranes parkinsonism improved with a MDS- UPDRS III score reduction from 39 to 21. Histology revealed arachnoid cystic material. We report on a rare case of recurrent symptomatic hemiparkinsonism resulting from arachnoidcysts.
Spinal cord atrophy following the resection of multiple intraspinal arachnoidcysts: case report and literature review. We report the first case of spinal cord atrophy developing 16 months after resection of multiple intraspinal arachnoidcysts. The patient presented with back pain and the cysts were successfully resected. Sixteen months later, her back pain recurred. Magnetic resonance imaging
Intradural symptomatic arachnoidcyst formation following non-instrumented lumbar decompression. Intradural arachnoidcyst is a rare complication of lumbar puncture, post-trauma or post-intraoperative durotomies. We aim to estimate the incidence of early intradural arachnoidcyst radiologically in non-instrumented posterior lumbar decompression among symptomatic patients, and establish clinical requested to investigate new or ongoing pain. Ten demonstrated an intradural arachnoidcyst - seven had no documented durotomy. Eight were primary operations, three were emergency operations. Statistically, we have not identified durotomy, primary-vs-revision surgery, and elective-vs-emergency surgery as risk factors. Two patients required revision operations, of these, one had a repeat post-operative
Arachnoidcysts on magnetic resonance imaging: just an incidental finding? To determine the clinical significance of arachnoidcysts. The scans of 6978 patients undergoing magnetic resonance imaging of the internal acoustic meatus for unilateral cochleovestibular symptoms were retrospectively reviewed. We identified the scans with arachnoidcysts, and assessed the statistical associations between the laterality, location and size of the arachnoidcyst, the laterality of symptoms, the patients' age and gender. In a total of 37 arachnoidcysts identified in 36 patients (0.5 per cent), no associations were identified between the laterality of symptoms and the laterality of the arachnoidcyst, regardless of its size or location. There were no significant associations between the location
Spinal intradural arachnoidcyst as a complication of insertion of an interspinous device. Spinal intradural arachnoidcysts (SACs) account for approximately 10% of total arachnoidcysts, and iatrogenic attribution is rare. A 50-year-old male presented with low back pain and severe radiating pain in his right leg along the S1 dermatome. He had an interspinous device (ISD) inserted 10 years earlier. Plain radiographs showed breakage and angular movement of the ISD at L4/5. Magnetic resonance imaging (MRI) of the lumbosacral spine disclosed multiple intradural cystic tumors in the entire lumbar region. He underwent removal of the ISD, laminectomy, and resection of the intradural cyst. The pathologic finding of the cystic tumor was compatible with arachnoidcyst. Antibodies to parasites
Supratentorial arachnoidcysts and seizures/epilepsy: A population study in community dwellers aged ≥20 years. Literature on the association between arachnoidcysts and seizures/epilepsy is inconsistent, and most series have been flawed due to recruitment bias. In this study, we aimed to assess the prevalence of supratentorial arachnoidcysts (SACs) in Atahualpa residents aged ≥20 years
Spinal intradural arachnoidcyst associated with diastematomyelia in an adult: a case report and review of literature. We report a case of a spinal intradural arachnoidcyst in a thirty year old female with a previously undiagnosed and untreated diastematomyelia. The cyst was located exactly between the two hemi-cords of the split cord malformation. The patient was treated successfully by laminoplasty and total removal of the cyst. Additionally, sectioning of the filium terminale was done in the same sitting by a separate incision. This case posed a diagnostic dilemma. Though the clinical findings favoured an extramedullary lesion, the possibility of cystic degeneration in the spinal cord due to the tethered cord syndrome could not be completely negated. Spinal intradural arachnoidcysts have
