Thunderclap headache: Diagnostic considerations and neuroimaging features
Thunderclap headache (TCH) is an acute and severe headache that has maximum intensity at onset; TCH can be primary or secondary. Primary TCH is diagnosed when no underlying cause is discovered; however, imaging is crucial in distinguishing secondary causes, which are wide-ranging. The radiologist should be aware of the list of potential diagnoses. Subarachnoid haemorrhage (SAH) is the most common cause of secondary TCH. Aneurysmal SAH accounts for the majority of cases, although other causes should also be considered and these include perimesencephalic haemorrhage, arteriovenous malformations, and dural arteriovenous fistu...

Contemporary management of pediatric lateral sinus thrombosis: A twenty year review
Conclusion: Lateral sinus thrombosis is a rare but treatable complication of otologic disease in the pediatric population, warranting a high index of suspicion. Management should include broad spectrum antibiotics and surgical removal of all perisinus infection. Anticoagulation is not definitively associated with improved outcomes and warrants further investigation.

A cloudy story: Guillain–Barré syndrome concealed by a spontaneous intracerebral haemorrhage
We present a case of Guillain–Barré syndrome (GBS), probably associated with influenza vaccine, occurring in a patient some days after a spontaneous haemorrhagic stroke. A 79-year-old woman was admitted to the neurosurgery department after a sudden severe headache, dizziness, and progressive generalised weakness. She had a history of hypertension and paroxysmal atrial fibrillation in dicumarolic therapy. Head CT scan showed a haemorrhagic stroke in left cerebellum, with compression on the fourth ventricle.

Clinical and Radiological Management and Outcome of Pregnancies Complicated by Cerebral Venous Thrombosis: A Review of 19 Cases
Conclusions: If magnetic resonance imaging is available, it should be used for the detection of CVT in all pregnant patients instead of computed tomography. Patients with parenchymal lesions, thrombophilia, and antiphospholipid syndrome had a greater risk of being left with neurologic sequelae. For pregnant patients with CVT, low molecular weight heparin in full anticoagulant doses should be continued throughout the pregnancy. Anticoagulant therapy did not appear to predispose patients to further intracranial hemorrhage.
