A 12-year-old girl presented with a supracollicular arachnoid cyst manifesting as a compressive headache. Neurological examination on admission revealed no deficit except bilateral papilledema. Stereotactic cyst puncture failed to perforate the cyst wall. The wall was then punctured using microforceps under neuroendoscopic guidance, followed by cystoperitoneal shunting. Her headache disappeared...

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...

Acquired torticollis can be the result of several different pathological mechanisms. It is generally related to trauma, tumors, and inflammatory processes of the cervical muscles, nerves, and vertebral synovia. Although upper respiratory tract and neck inflammation are common causes of acute febrile torticollis in children, diseases with as yet undefined relationships may also result in tortico...

∑ Herniation of the spinal cord through a dural defect is a rather rare deformity and very easily misdiagnosed as retromedullary occult intraspinal arachnoid cyst or meningocele. The possible origin of the dural defect can be traumatic, iatrogenic or unknown, so in these cases, congenital with great probability. On the thoracal part of the spinal column it shows a rather characteristic and misl...

Arachnoid cysts are a congenital disorder, and most cases begin during infancy; however, onset may be delayed until adolescence. Here we present an unusual case of atypical Paraplegia with Lymphoedema, with onset during adolescence and rapid progression in a young female patient who showed the characteristic appearance of cyst on magnetic resonance imaging (MRI) of spinal cord. This report inte...

Arachnoid cysts involving the cerebellopontine angle are an unusual cause of hemifacial spasm. The case is reported of a 71-year old woman presenting with a right hemifacial spasm and an ipsilateral arachnoid cyst. Preoperative magnetic resonance imaging findings suggested a neurovascular compression caused by displacement of the facial-acoustic complex and the anterior inferior cerebellar arte...

Arachnoid cysts are benign developmental cysts that occur throughout the cerebrospinal axis in relation to the arachnoid membrane and the subarachnoid space(l). Intracranial arachnoid cysts usually occur in close proximity to arachnoid cisterns, most often in the sylvian fissure(2) and they become symptomatic in early childhood(3). We report an interhemispheric arachnoid cyst associated with ag...

We present the case of a 49-year-old woman who presented with acute, nonprogressive left sensorineural hearing loss and benign positional vertigo that was associated with an arachnoid cyst of the cerebellopontine angle. The presence of the lesion was documented by MRI examinations that were obtained 7 years apart. Arachnoid cysts at the cerebellopontine angle are usually found incidentally on M...
