INTRODUCTION: Spinal bronchogenic cysts are rare findings, with only four cases of lumbar bronchogenic cysts reported in the literature. All of these bronchogenic cysts involved the conus medullaris. We present the first case of a lumbar bronchogenic cyst and arachnoid cyst arising from the cauda equina in a 68-year-old male. Uniquely, this bronchogenic cyst also contained components of an arachnoid cyst. METHODS: Magnetic resonance imaging (MRI) demonstrated a compressive cystic lesion at the level of the L3 vertebra splaying the cauda equina...

We describe a rare case and novel management strategy of painful trigeminal neuropathy caused by an arachnoid cyst confined to Meckel's cave. A 57-year-old female presented with several years of progressive trigeminal pain and signs of trigeminal deafferentation, including sensory loss, corneal anesthesia and mastication muscle atrophy. Medical treatment with carbamazepine provided partial and temporary pain control. Surgical treatment was eventually performed by aspiration of the arachnoid cyst through the foramen ovale using a percutaneous approach...

Arachnoid cyst is a benign, congenital space-occupying brain lesion, which has been found in patients with schizophrenia. The association between arachnoid cyst and schizophrenia remains controversial, but the location of the arachnoid cyst may give rise to a specific symptom presentation in schizophrenia. We present a 31-year-old woman with an established diagnosis of schizophrenia coexisting with a large cerebellar arachnoid cyst who presented mainly with delusions of control. This cerebellar arachnoid cyst and schizophrenia may have been found together coincidentally or brain dysfunction due to this cerebellar arachnoid cyst may have caused or contributed to the appearance of psychotic symptoms...

BACKGROUND: Spinal extradural arachnoid cysts (SEAC) are relatively rare and usually asymptomatic. They preferentially are situated in the thoracic extradural space, and almost always dorsal. SEACs may present with back pain and/or cord compression symptoms. Needle aspiration, needle fenestration or open surgical resection/fenestration have been reported as treatment modalities. CASE DESCRIPTION: We present a 35-year-old woman who complained of radiating pain from the right lower thoracic region of her back towards the right inguinal region which was aggravated upon defecation and straining...

INTRODUCTION: Arachnoid cysts are benign developmental anomalies of arachnoid membrane origin that can occur anywhere along the neuro-axis. They are believed to develop from the splitting or duplication of the arachnoid membrane by CSF that is trapped by a ball-valve mechanism. Intracranial arachnoid cysts have only been described as intradural lesions while spinal arachnoid cysts can be both intradural or extradural. CASE REPORT: After an extensive literature review, we report the first case of an intracranial, extradural arachnoid cyst in a 5-yearold girl...

Intracranial arachnoid cysts need to be operated on when they are causing symptoms and aesthetic problems. The aim of this case report was to describe a new method of reconstructing the skull by eliminating a left frontal bone deformity by turning the inside out and the outside inward, which provided good aesthetics and protected the region of surgical interest after the removal of an arachnoid cyst of the left frontal lobe.

PURPOSE: Less than 0.5% of arachnoid cysts are intraventricular in origin. We review our experience with endoscopic surgery for intraventricular arachnoid cysts in children. METHODS: This is a retrospective review of children with intraventricular arachnoid cysts who underwent surgery between 2005 and 2016. Clinical notes and imaging were reviewed. RESULTS: Twenty-nine patients with endoscopically treated intraventricular arachnoid cysts were identified (M/F = 17:12; median age = 1...

Encephalocraniocutaneous lipomatosis (ECCL) or Haberland syndrome is an uncommon sporadic neurocutaneous syndrome of unknown origin. The rarity and common ignorance of the condition often makes diagnosis difficult. The hallmark of this syndrome is the triad of skin, ocular and central nervous system (CNS) involvement and includes a long list of combination of conditions. Herein we report a case of a 5-month-old male child who presented to our centre with complaint of seizure. The patient had various cutaneous and ocular stigmatas of the disease in the form of patchy alopecia of the scalp, right-sided limbal dermoid and a nodular skin tag near the lateral canthus of the right eye...

The prevalence of syringomyelia (SM) caused by adhesive arachnoiditis (AA) is 2 to 4 cases per 100000 population. Surgical treatment of this pathology usually includes implantation of shunts into the cyst cavity or opening and drainage of the cavity. In this case, SM continues to progress in 72-100% of patients. Unsatisfactory outcomes of this surgical approach necessitate searching for other treatment options. PURPOSE: To define the optimal amount of surgery for SM associated with AA and the criteria for assessment of surgery outcomes...

A family with familial spinal extradural arachnoid cyst is presented. A 14-year-old boy had an extensive T-8 through L-2 dorsal extradural arachnoid cyst with spinal cord compression and slowly progressive myelopathy. His mother had presented 4 years earlier with acute excruciating back pain due to the combination of a lumbar extradural arachnoid cyst at L2-4 and an extruded disc at L3-4. The literature is reviewed in light of the pathogenesis, imaging, and surgical technique required for treatment.

We report the case of a 40-year-old man presenting with focal headache and a bulge at the right parietal bone, diagnosed as an intradiploic arachnoid cyst. The cyst wall included "meningothelial hyperplasia," which is a rare finding. While over 40 cases of intradiploic arachnoid cysts have been reported to date, meningothelial hyperplasia in an intradiploic arachnoid cyst does not appear to have been reported. We also discuss the pathological findings of arachnoid cysts with meningothelial hyperplasia and mechanisms of enlargement of the arachnoid cyst...

Quadrigeminal arachnoid cysts (QAC) are usually accompanied by a symptomatic obstructive hydrocephalus. Several endoscopic and surgical treatments exist; however, the critical location of these cysts further complicates treatment and usually more than one procedure is required. In this report, a 31 year old female with QAC and associated obstructive hydrocephalus was successfully treated with stereotactic placement of a permanent ventricular - cystic stent (intraventricualr - cystic catheterization) in single - session...

An 18-year-old patient developed multiple infarcts, nine days after endoscopic fenestration of a large arachnoid cyst. We consider vasospasm to be the most likely cause, presumably triggered by a chemical meningitis. Although mostly seen after subarachnoid haemorrhage, vasospasm can also occur after traumatic brain injury, brain surgery or meningitis.

BACKGROUND: Ecchordosis physaliphora (EP) is a benign notochordal remnant, which is usually asymptomatic. Herein, we report a case of symptomatic large EP mimicking an epidermoid cyst. CASE DESCRIPTION: A 44-year-old female presented with right facial dysesthesia. Brain magnetic resonance imaging (MRI) showed a mass with a diameter of 3.2 cm that was hypointense on T1-weighted images (T1WI), hyperintense on T2-weighted images (T2WI), iso-to-hyperintense on diffusion-weighted (DW) images, and hyperintense on apparent diffusion coefficient (ADC) map (1...

INTRODUCTION: The advent of chromosome microarray analysis (CMA) for evaluation of patients with multiple congenital anomalies has made it possible to define chromosomal imbalances with greater precision and resolutions significantly smaller than possible by standard G-banded chromosome analysis. We describe two patients with novel chromosomal anomalies involving chromosome 22q13, a locus also associated with Phelan-McDermid syndrome (PMS). OBJECTIVE: We aim to characterize the novel phenotypic and genotypic findings of two patients with 22q13 microdeletions, distinct from PMS, comparing and contrasting with features of PMS...

Giant dorsolumbar spinal arachnoid cysts are a complex, poorly understood, and difficult to manage clinical entity. Traditional CT myelography is technically difficult to use in these cases to detect the site of leakage preoperatively. The authors report a novel technique for detecting the site of the leak by using sequential, dynamic intraoperative MR myelography. To the authors' knowledge, there is no other similar report in the literature.
