Comparative Study
CSF spectrophotometry in the diagnosis and exclusion of spontaneous subarachnoid haemorrhage.
To assess the sensitivity and specificity of CSF spectrophotometry for the detection of xanthochromia in patients with clinical symptoms suggestive of subarachnoid haemorrhage (SAH) but normal cranial computed tomography (CT). ⋯ CSF spectrophotometry has an unacceptably low specificity and positive predictive value, which greatly limit its use as a clinical tool.

The Neurosurgical Advanced Training curriculum of the Royal Australasian College of Surgeons (RACS) is currently undergoing change. Given the high standard of neurosurgery in Australia and New Zealand, it may be questioned why such change is necessary. ⋯ The curriculum must also adapt to the changing training environment, particularly the effects of reduced working hours, reducing caseloads due to shorter inpatient hospital stays and restricted access to public hospital beds and operating theatres, and the effects of sub-specialisation. A formal review of the curriculum is timely.

We report a 20-year-old man who developed a chronic subdural haematoma (CSDH) after riding a "giant" roller coaster. The patient had a past history of a subdural hygroma, diagnosed six weeks after a motorcycle accident. ⋯ Three weeks later, he developed a CSDH requiring surgical evacuation. Roller coaster riding, associated with high velocities and extreme acceleration/deceleration forces is a modern cause of CSDH in the young, which may be increasing due to ever-faster rides.

Case Reports
Spontaneous spinal epidural haematoma: report of two cases and review of the literature.
The clinical presentation, investigation, management and outcome of two patients with spontaneous spinal epidural haematoma (SSEH) are presented. CT myelogram revealed an extradural compressive lesion in one patient and MRI confirmed extradural haemorrhage in the second. ⋯ One patient made a complete recovery and the other made no neurological recovery. The clinical presentation, diagnosis, treatment and factors determining the outcome of SSEH are discussed and the literature reviewed.

Case Reports
Tophaceous gout of the lumbar spine mimicking infectious spondylodiscitis and epidural abscess: MR imaging findings.
We report a case of surgically proven tophaceous gout of the lumbar spine at the L5-S1 level that mimicked infectious spondylodiscitis and epidural abscess on magnetic resonance (MR) images in a 65-year-old woman. The spinal tophi were hypointense on T1-weighted images; focally and strongly hyperintense on T2-weighted images; and heterogeneously, marginally enhancing on contrast-enhanced T1-weighted images. The aim of this report is to emphasize the importance of considering this disease entity in the differential diagnosis of an epidural mass in a patient with chronic back pain.
