Background: Many intracranial lesions can induce psychotic symptoms. Arachonoid cyst is one of the suspicious etiologies. A possible link between arachnoid cyst and psychosis gives an interest to the pathogenesis of psychotic symptoms. Here, we present a case of schizophrenia with a large cerebellar arachnoid cyst. Case Presentation: Ms. Lu is a 31-year-old woman with schizophrenia for 7 years...

Spinal subarachnoid hemorrhage is a rare condition that usually occurs because of secondary causes and idiopathic spontaneous ones are extremely rare. We report a 56-year-old woman who presented with severe headache, neck pain and urinary retention. Magnetic resonance imaging revealed subarachnoid hemorrhage that extended from T1 to lumbar vertebrae. She was treated conservatively and symptoms ...

Recognizing syndromes which mimic ALS is crucial both to avoid giving this diagnosis erroneously and since there may be appropriate treatments. We report a 63-year-old woman diagnosed with possible ALS five years ago based on upper and lower motor neuron signs with typical electrophysiology and normal cranial MRI. At reassessment, spinal MRI revealed a cervicothoracic cyst with cord compression...

Arachnoid cysts are relatively uncommon in infancy and are incidental findings in intracranial imaging in pediatric patients. Presentation at a younger age is usually associated with cyst enlargement. Arachnoid cysts are considered to be congenital in origin but the natural history and prevalence is not well defined. Here we report a case of a 2 months old male infant with nonspecific illness w...

Arachnoid cysts are thin-walled fluid-filled cavities that are uncommon causes of intracranial mass lesions [1 , 2]. These lesions have been found in various locations, both supratentorial and infratentorial [1 , 3-7] . This report describes a case in which the arachnoid cyst arose from the tela choroidea and occupied the cistern of the velum interpositum. The cyst caused symptoms similar to th...

Few case reports discuss suspected psychiatric disturbances secondary to arachnoid cysts. To the best of our knowledge, psychosis from arachnoid cysts has not been reported in the recent literature. This case report discusses our experience with a 55-year-old male patient who manifested multiple psychotic episodes suspected in association with an arachnoid cyst. During the initial examinations,...

INTRODUCTION Hemorrhagic complications of arachnoid cysts have been reported, extensively presenting with subdural or intracystic hematoma after trauma, but presentation with extradural hemorrhage is very rare. In this paper, we report the case of a patient with an arachnoid cyst who developed an extradural hematoma after a subtle head injury. Our patient presented with very mild symptoms in sp...

Surgical Treatment of Suprasellar Arachnoid Cyst Dr. A. Barth, Neurochirurgische Klinik, Inselspital, CH-3010 Bern (Switzerland) Dear Sir, Suprasellar arachnoid cysts often present with hydrocephalus [1, 2]. Even if hydrocephalus can usually be treated without permanent shunting devices, the best surgical approach remains presently controversial concerning the operative risks and the avoidance ...

Neuroendoscopy is considered a safe treatment option for intracranial arachnoid cysts. However a variety of complications has been reported after such interventions. Here we present the first case of a chronic subdural hematoma two months after the combined treatment of a supracellar arachnoid cyst with endoscopic third ventriculostomy and cyst fenestration.
