Background Hospital-based studies have reported variable associations between outcome after spontaneous intracerebral hemorrhage and peri-hematomal edema volume. Aims In a community-based study, we aimed to investigate the existence, strength, direction, and independence of associations between intracerebral hemorrhage and peri-hematomal edema volumes on diagnostic brain CT and one-year functional outcome and long-term survival. Methods We identified all adults, resident in Lothian, diagnosed with first-ever, symptomatic spontaneous intracerebral hemorrhage between June 2010 and May 2013 in a community-based, prospective inception cohort study. We defined regions of interest manually and used a semi-automated approach to measure intracerebral hemorrhage volume, peri-hematomal edema volume, and the sum of these measurements (total lesion volume) on first diagnostic brain CT performed at ≤3 days after symptom onset. The primary outcome was death or dependence (scores 3–6 on the modified Rankin Scale) at one-year after intracerebral hemorrhage. Results Two hundred ninety-two (85%) of 342 patients (median age 77.5 y, IQR 68–83, 186 (54%) female, median time from onset to CT 6.5 h (IQR 2.9–21.7)) were dead or dependent one year after intracerebral hemorrhage. Peri-hematomal edema and intracerebral hemorrhage volumes were colinear ( R2 = 0.77). In models using both intracerebral hemorrhage and peri-hematomal edema, 10 mL increments in intracerebral hemorrhage (adjusted odds ratio (aOR) 1.72 (95% CI 1.08–2.87); p = 0.029) but not peri-hematomal edema volume (aOR 0.92 (0.63–1.45); p = 0.69) were independently associated with one-year death or dependence. 10 mL increments in total lesion volume were independently associated with one-year death or dependence (aOR 1.24 (1.11–1.42); p = 0.0004). Conclusion Total volume of intracerebral hemorrhage and peri-hematomal edema, and intracerebral hemorrhage volume alone on diagnostic brain CT, undertaken at three days or sooner, are independently associated with death or dependence one-year after intracerebral hemorrhage, but peri-hematomal edema volume is not.

A previously well, 14-month-old girl presented with acute decreased level of consciousness. There was no history of trauma, systemic upset or significant family history. Blood pressure was within normal range and no focal neurological deficit was elicited on examination. Neuroimaging revealed a subarachnoid haemorrhage secondary to a basilar tip aneurysm. Patient underwent endovascular embolisation with good clinical outcome. Follow-up MRI revealed anterior circulation vasospasm, and although clinically asymptomatic, she was treated with a calcium channel antagonist. She was later discharged home with no neurological deficit. Follow-up MRI 3 months following presentation suggested recurrent formation of the aneurysmal sac. The patient then underwent elective endovascular repair 2 months later and was discharged home on antiplatelet therapy with planned close outpatient clinical and radiological surveillance.

This is a transcript of a scientific conference on the subject of prenatal surgery for spina bifida. It represents the views of three patients, an obstetrician, a postnatal neurosurgeon, a neonatologist, a paediatric neurologist, two surgeons who practice open spina bifida foetal surgery, a fetoscopic surgeon and an obstetrician experienced in randomised trials and systematic reviews. Implications for current practice and recommendations for future research are also discussed in detail.

Background and Purpose— The characteristics of intracerebral hemorrhage (ICH) may vary by ICH location because of differences in the distribution of underlying cerebral small vessel diseases. Therefore, we investigated the incidence, characteristics, and outcome of lobar and nonlobar ICH. Methods— In a population-based, prospective inception cohort study of ICH, we used multiple overlapping sources of case ascertainment and follow-up to identify and validate ICH diagnoses in 2010 to 2011 in an adult population of 695 335. Results— There were 128 participants with first-ever primary ICH. The overall incidence of lobar ICH was similar to nonlobar ICH (9.8 [95% confidence interval, 7.7–12.4] versus 8.6 [95% confidence interval, 6.7–11.1] per 100 000 adults/y). At baseline, adults with lobar ICH were more likely to have preceding dementia (21% versus 5%; P =0.01), lower Glasgow Coma Scale scores (median, 13 versus 14; P =0.03), larger ICHs (median, 38 versus 11 mL; P P P =0.02) than those with nonlobar ICH. One-year case fatality was lower after lobar ICH than after nonlobar ICH (adjusted odds ratio for death at 1 year: lobar versus nonlobar ICH 0.21; 95% confidence interval, 0.07–0.63; P =0.006, after adjustment for known predictors of outcome). There were 4 recurrent ICHs, which occurred exclusively in survivors of lobar ICH (annual risk of recurrent ICH after lobar ICH, 11.8%; 95% confidence interval, 4.6%–28.5% versus 0% after nonlobar ICH; log-rank P =0.04). Conclusions— The baseline characteristics and outcome of lobar ICH differ from other locations.

Hemimegalencephaly is a rare sporadic brain malformation characterized by enlargement of one cerebral hemisphere. The classical clinical triad consists of intractable epilepsy, severe psychomotor delay and hemiparesis. In this report, we describe a case of a 3-year-old girl, with all the radiological features of severe hemimegalencephaly but with a comparatively benign clinical course. She had no hemiparesis, mild delay and no seizures. An extensive literature review reveals only one previously reported case of hemimegalencephaly with the absence of seizures, as part of case series. This is the first dedicated case report, with clinical description and radiological images, of this entity.

We present a case of a 48-year-old man who was initially thought to have had a brainstem stroke and was clinically ‘locked-in’. Upon investigation, a petrous apex dural atriovenous fistula was identified causing profound brainstem venous hypertension. Surgical clipping lead to complete neurological recovery.

Although uncommon, vertebral artery pseudoaneurysms harbour significant risk of embolic stroke and their presence should be considered in cases of blunt cervical trauma. We illustrate a case of a traumatically ruptured vertebral artery pseudoaneurysm treated with coil embolisation.

The discovery of air in the cavernous sinus may cause some alarm. It may well, however, simply be a consequence of retrograde air embolism from venous cannulation. It rarely has any adverse effects and is self-limiting in nature. We provide an illustrative case report.

The authors present an unusual case of a healthy young male who developed a spontaneous subdural haematoma. Headache was followed by blurring of vision and left upper limb symptoms. The diagnosis was made from a CT scan. Symptoms resolved with surgical decompression. The authors explore the risk factors and pathophysiology implicated in this condition. The authors demonstrate that apparently ‘healthy’ pursuits can have significant consequences, but the physician must also exclude serious underlying risk factors for bleeding, which the authors discuss.
