Intradiploic cysts in the posterior fossa are rare. We report a post-traumatic intradiploic leptomeningeal cyst in an adult and review the diagnosis and pathogenesis of this lesion. A 28-year-old woman presented with a headache and a hard mass in the occipital region. ⋯ The dural defect was sutured primarily and covered with the autogenous outer table. An intradiploic cyst of the occipital bone can be detected in adults and might be caused by remote head injuries during childhood. Prompt surgical repair of the dural and bony defect in an adult patient has an excellent prognosis.

Dolichoectasia is an angiopathy characterized by dilatation, elongation, and tortuosity of the brain arteries. It most frequently involves the vertebral and basilar arteries; involvement of both the vertebrobasilar and carotid systems is rare. We present a patient with fatal dolichoectasia involving both the vertebrobasilar and carotid artery systems.

The past decade (1999-2009) has witnessed a dramatic increase in the use of electrical stimulation to treat chronic, intractable pain. The implantation of electrodes in close proximity to peripheral nerves, known as peripheral nerve stimulation, has been enthusiastically adopted by neurosurgeons and interventional pain specialists. ⋯ The potential application of peripheral neuromodulation to relatively common and frequently disabling conditions such as migraine and lower back pain represents an exciting phase in the evolution of contemporary pain surgery. We review the available evidence relating to the use of peripheral nerve stimulation for the treatment of medically refractory, chronic non-cancer pain in a variety of clinical situations, highlight the absence of randomised controlled studies, and emphasise the need for scientifically sound research in this field.

Seventy-one patients from northern Sweden were diagnosed with chronic subdural haematomas (CSDH) and treated at the Department of Neurosurgery at Umeå University Hospital over 12 months. Fifty-four patients with CSDH had a history of head trauma (trauma group), while 17 patients had no previous head trauma (non-trauma group). In the non-trauma group 71% of patients were treated with anticoagulants or antiplatelet aggregation agents (AAA) compared to 18% in the trauma group. ⋯ The recurrence rate for all patients was 17%. These findings confirm that the use of anticoagulants and AAA is over-represented in patients with non-traumatic CSDH. In our study, recurrence was not associated with previous use of anticoagulants or AAA.

Venous air emboli from intravenous catheterization: a report of iatrogenic intravascular pneumocephalus.
Pneumocephalus in the absence of a recent intracranial or intrathecal procedure is a significant radiographic finding and may be clinically relevant. Pneumocephalus secondary to intravenous catheterization may be a more common finding than previously expected. ⋯ This unexpected radiographic finding should not necessarily be cause for alarm, and there is no evidence that intravenous pneumocephalus alone is harmful. We present a patient with intravenous pneumocephalus and a review of the literature.
