Arachnoid cysts are a relatively common finding in adult patients, especially with the advent of advanced imaging techniques. The overall incidence ranges from 1-2%, and the majority are clinically silent1,2 . Arachnoid cysts are postulated to arise by congenital anomalies or trauma1 . De novo formation of arachnoid cysts has been reported, but is exceptionally rare and mostly found in the pediatric population after head trauma3-5 . There have only been two reported cases of symptomatic de novo arachnoid cyst formation in adult patients to date, both with histories of head trauma6,7 ...

Spinal extradural arachnoid cyst (SEAC) is a rare cause of spinal cord compression. Bifocal location of thoracic and sacral SEACs is rarely reported in the literature. We report a case of thoracic spinal cord compression by SEAC associated with asymptomatic multiple sacral Tarlov cysts (TC). The surgical management and postoperative outcome of the patient are discussed. A 34-year-old woman was referred to the hospital for acute thoracic pain with a history of chronic long-standing back pain. She complained of walking difficulties...

Arachnoid cysts constitute mere 1% of all the non-traumatic intracranial space occupying lesions and only 10% of these are present in the infra-tentorial compartment. We hereby report a case of a ten month-old female child with a tri-compartmental arachnoid cyst. It spanned both the infra-tentorial and supra-tentorial compartment of the intracranial space. In addition to this, it was also herniating into the extra-cranial compartment through a congenital defect in the parietal bone. The child was brought to us with a disfiguring swelling over her scalp which was progressively increasing in size...

A 12-year-old female presented with complaints of progressive visual impairment in both her eyes. On clinical examination, she was short for her age and her ophthalmoscopic examination revealed bilateral optic atrophy. Computed tomography of the patient revealed multiple expansile lytic lesions of mandible suggesting cherubism. The optic atrophy was confirmed on magnetic resonance imaging, which additionally revealed bilateral retrocerebellar arachnoid cysts. This association of cherubism with optic atrophy and short stature was grouped as orphan disease by National Institutes of Health and only one case was reported in the literature so far...

Spinal extradural arachnoid cysts are rare lesions which typically involve the thoracic spine and are an asymptomatic condition of unknown origin. They may also produce symptoms by compressing the spinal cord or nerve roots. Surgery is the treatment of choice in such lesions, but asymptomatic patients can be managed conservatively. We present a case of symptomatic, probable traumatic origin, spinal arachnoid cyst at our center in Hospital Kuala Lumpur, Malaysia. Magnetic resonance imaging spine showed well-defined, nonenhancing extradural cystic lesion from T5 to T6 vertebrae level compressing spinal cord anteriorly...

BACKGROUND: The traumatic complication of an arachnoid cyst (AC) with intra-cystic and subdural hematoma has been reported in many cases. However, a unilateral extradural hematoma (EDH) as a complication of AC is extremely rare. Most arachnoid cysts are unilateral and are located in the middle cranial fossa. Bilateral temporal AC alone is an extremely rare condition, and a bilateral EDH on top of a bilateral temporal AC has never been reported in the literature. CLINICAL PRESENTATION: We report the case of a 25-year-old male with a known bilateral AC who was involved in a car accident and developed a bilateral temporal EDH...

Background: Perineural cysts formed within the nerve-root sheath at the dorsal root ganglion. They are most commonly located in the arachnoid covering the junction of the dorsal ganglion and nerve root. They are usually asymptomatic, incidental findings, usually located in the lumbar and sacral region of the spinal canal. It is important to consolidate the imaging findings of this rare disease so clinicians can become more clinically relevant in the evaluation of these cysts. Case: Herein we report a case of perineural cyst misdiagnosed with hydrosalpinx by pelvic ultrasonography and finally diagnosed with magnetic resonance image...

The appearance of a subdural hygroma after the rupture of an arachnoid cyst wall is extremely rare, with very few cases described in the literature. Most cases are due to a traumatic cause. The therapeutic approach in symptomatic cases is controversial, with a current tendency toward conservative management initially. In those cases that require surgical treatment, multiple therapeutic options are available, with fenestration techniques being recommended as first-line treatment. We describe 2cases treated in our centre and review the literature...

Spinal arachnoiditis (SA) is an extremely rare and delayed complication of subarachnoid hemorrhage (SAH). Little is known about its underlying pathogenesis and subsequent clinical course. A middle-aged patient presented with the worst headache of her life and a grade 3 SAH of the basal-cisterns and posterior fossa was identified on Computed Tomography scans (CT). Angiography revealed a ruptured dissecting aneurysm of the left vertebral artery (VA-V4), as well as an unruptured left Anterior Cerebral Artery (ACA-A1) aneurysm...

Background: Hereditary tumour predisposition syndromes may increase the risk for development of thyroid nodules at a young age. We present the case of an adolescent female with Cowden syndrome who had some atypical phenotypic features which overlapped with the DICER1 syndrome. Material and Methods: A 17-year-old female presented with a 3-month history of progressive right neck swelling. Fine needle cytology of the thyroid revealed a follicular neoplasm with features suggestive of follicular variant of papillary thyroid carcinoma and she underwent a hemithyroidectomy...

A 22-year-old man was admitted with gradually aggravating stereotypic head movement with hypomania. Brain magnetic resonance imaging showed a large suprasellar arachnoid cyst extending into the third ventricle, with obstructive hydrocephalus, characteristic of bobble-head doll syndrome. Endoscopic fenestration of the suprasellar arachnoid cyst was performed. Stereotypic head movement stopped immediately after surgery and hypomanic symptoms gradually improved within a month. During 4 years of follow-up observation without medication, neuropsychiatric symptoms did not relapse...

Arachnoid cysts are an uncommon postoperative complication and can result in back pain, radiculopathy, and/or cauda equina syndrome. For symptomatic postoperative arachnoid cysts, surgical management is the accepted treatment. While excision of arachnoid cysts is the preferred surgical method, cysts with adhesions to nerve roots and/or dura can be treated with cyst fenestration to reduce morbidity of excision. Surgeons should be prepared for dural defects after cyst excision, which can require dural grafting and lumbar drains for cerebrospinal fluid diversion...

Background: Intracranial arachnoid cysts are space-occupying lesions that typically remain stable or decrease in size over time. Cysts in infants younger than 1 year of age are remarkably different from those in older children and adults in terms of cyst localization and enlargement. Arachnoid cysts of the posterior fossa (PFACs) are very rare in infants and do not typically grow or present with clinical symptoms, such that surgical treatment is generally considered to be unnecessary...
