Cutaneous metastasis from glioblastoma.

A rare case of glioblastoma with isolated cutaneous metastasis adjacent to the scar site is described. Its pathogenesis and clinical significance are discussed.

Idiopathic spinal epidural lipomatosis.

We report a rare case of paraparesis caused by thoracic spinal epidural lipomatosis in a female patient who did not have any recognized predisposing factor for this condition.

Urinary bladder calculi complicating ventriculo-vesical shunt.

A rare case of vesical calculi complicating the procedure of ventriculo-vesical shunt is presented. In addition to highlighting technical difficulties in placing shunt catheters into the urinary system, the potential complications are discussed. We consider this route of cerebrospinal fluid(CSF) diversion less physiological compared with the peritoneal, pleural or the venous sites, and discourage use of the urinary bladder as the drainage site for the shunting of CSF.

Wrapping and coating of cerebral aneurysms: history, evolution and surgical management after a re-bleed.

Wrapping or coating of ruptured cerebral aneurysms was an acceptable method of surgical treatment until the 1980s. Occasionally, patients still present with a re-bleed. Management of these patients can be challenging. The author describes his experience of surgically treating ruptured aneurysms that have been previously wrapped. Technical issues in the surgical treatment are discussed with three illustrative cases of aneurysms at different locations encountered from 1999 to 2003. Despite operative difficulties satisfactory surgical results can be accomplished in the majority of these cases.

Isolated conjugate gaze palsy after frontal lobe tumour surgery.

Isolated conjugate gaze palsy following unilateral frontal lobe surgery is uncommon. When it does occur, usually it recovers within hours. We report a case of isolated conjugate gaze palsy which persisted for four weeks post-operatively before recovery commenced.

Meningioma presenting with transient ischaemic attacks.

A case of sphenoid wing meningioma mimicking the presentation of a transient ischaemic attack (TIA) is described. Based on findings from neuroimaging in this case, possible explanations of the mechanism of this uncommon presentation of meningiomas are discussed and the literature is reviewed.

Subarachnoid haemorrhage and akinetic mutism.

Two rare cases of akinetic mutism induced by aneurysmal subarachnoid haemorrhage are reported. The literature is reviewed, the possible pathophysiological mechanism of akinetic mutism is considered and the association between these two conditions is explored with an attempt to address the roles of medical treatment and surgery and to discuss prognosis.

Meningiomas induced by high dose cranial irradiation.

The authors present four patients with a history of high dose cranial irradiation, who were diagnosed years later to have symptomatic meningiomas requiring surgical management. Relevant literature pertaining to these rare tumours is reviewed and their unusual characteristics highlighted. Their aetio-pathogenesis and management strategies are discussed.

Terson's syndrome as the sole presentation of aneurysmal rupture.

The authors report a rare case of aneurysmal haemorrhage that presented with Terson's syndrome without any classical features of subarachnoid haemorrhage. The mechanism of this phenomenon is discussed and the importance of its identification is highlighted.

Fibrosarcoma of the brachial plexus presenting in childhood.

We report a case of malignant fibrosarcoma involving the brachial plexus presenting in childhood. Primary malignant tumours of the brachial plexus are rare entities. In particular, fibrosarcoma of the brachial plexus occurring in a child has not been previously reported. Dilemmas in resolving the management and long-term consequences of this condition are discussed.

'Plunging' during burr hole craniostomy: a persistent problem amongst neurosurgeons in Britain and Ireland.

The inadvertent 'plunging' of an instrument into the cranial cavity is a feared complication of drilling a burr hole and while anecdotes abound, little is known about the extent or the consequences of this problem. A survey by anonymous postal questionnaire of 304 neurosurgeons in Britain and Ireland was conducted to analyse the extent of this complication. Of respondents, 65.6% had experienced 'plunging', 22.3% having 'plunged' at least twice, indicating a high prevalence of this complication. The Cushing perforator was implicated by most. 'Plunging' carried a 12% risk of death or permanent neurological morbidity. The authors analyse the prevalence and significance of this preventable complication, and discuss various options available to minimize its occurrence.

Delayed post-surgical development of dural arteriovenous fistula after cervical meningocele repair.

A 34-year-old female patient presented with an intracranial subarachnoid hemorrhage and was found to have a dural arteriovenous fistula at the site of previous cervical meningocele repair. Subsequent occlusion was achieved with endovascular embolization. To our knowledge, the phenomenon of the development of a spinal dural fistula at the site of a meningocele repair has not been recorded before.
