Despite recent advances in the management of aneurysmal subarachnoid haemorrhage delayed ischaemic deficits from cerebral vasospasm remains a major cause of morbidity and mortality. As magnesium is a potent cerebral vasodilator we have introduced routine supplementation in patients presented with subarachnoid haemorrhage to determine whether there has been a reduction in the incidence of cerebral vasospasm. ⋯ From our pilot study it appears that magnesium supplement has a beneficial role in the prevention of cerebral vasospasm following aneurysmal subarachnoid haemorrhage. Further studies would seem justified.

We report the case of a 32-year-old South Korean male who presented with bilateral leg weakness, spastic gait and associated sensory loss from below the T5 dermatome. MRI and CT scans of the spine confirmed the presence of calcified ligamentum flavum from T1-T6. ⋯ This case review will discuss the differences that exist between ossification of the posterior longitudinal ligament (OPLL) and ossification of the ligamentum flavum (OLF), but also the similarities at a molecular and possibly at a genetic level. We have reviewed the reported literature of patients presenting with progressive lower limb spacity due to OLF, and an excellent outcome is achieved using decompressive laminectomy.

Intracranial dural arteriovenous fistula (DAVF) is an uncommon neurosurgical condition; in particular, it has been infrequently reported in Korea. To understand the general clinical characteristics of DAVFs, the authors reviewed 53 cases and analyzed factors affecting DAVF hemorrhage of and treatment outcome. Since 1980 we have encountered 480 pial and 53 DAVFs, a ratio of 9.1 to 1. ⋯ Endovascular treatment is preferred in the majority of cases except tentorial DAVF. The goal of embolization in cavernous DAVF is the alleviation of symptoms, not angiographic cure. But transverse-sigmoid sinus DAVF with venous restriction and leptomeningeal drainage should be treated aggressively.

Case Reports
Growth hormone-secreting pituitary adenoma confined to the sphenoid sinus associated with a normal-sized empty sella.
We present a case of growth hormone (GH)-secreting ectopic pituitary adenoma confined to the sphenoid sinus associated with a normal-sized empty sella. It has been well known that acromegaly is sometimes associated with an empty sella. ⋯ Primary empty sella existed originally, and the pituitary adenoma developed later. The adenoma extended into the sphenoid sinus because of the pulsatile intracranial cerebrospinal fluid pressure.
