1/14. Migrainous spasm simulating carotid dissection: a pitfall in MR arteriographic findings.

    An MR arteriogram obtained in a patient with migraine headaches during prodrome showed features of carotid dissection. A repeated study conducted within minutes demonstrated complete patency. Vascular spasm was proposed to be the cause. Migraine occurs in more than 10% of the population. The possibility of misdiagnosing a vascular spasm as carotid dissection is real and should be guarded against since there are great prognostic and treatment implications.

2/14. Pseudomigraine with prolonged aphasia in a child with cranial irradiation for medulloblastoma.

    We report a 12-year-old child with episodes of migraine-like headaches with visual and motor auras a year after the surgical resection and radiation therapy for medulloblastoma The patient presented with an episode of headache, prolonged aphasia, right hemiparesis, status epilepticus, and salt wasting. There was no evidence of a structural lesion. The neurologic deficits resolved over a period of 6 weeks. Because of the progressive deterioration in neurologic deficits, the patient underwent an extensive battery of laboratory tests and multiple neuroimages, all of which were normal. The unusually prolonged neurologic deficit in this patient without demonstrable structural lesions and his eventual complete recovery were most likely caused by ischemia in the left hemisphere secondary to vasospasm. This presentation mimics migraine headache. Evidence suggesting that this represents a long-term complication of treatment of children with central nervous system neoplasia is presented.

3/14. Reversible segmental cerebral vasoconstriction (Call-Fleming syndrome): are calcium channel inhibitors a potential treatment option?

    The Call-Fleming syndrome is characterized by sudden onset of thunderclap-like headache and focal neurological deficits. The pathophysiological correlate is a reversible segmental cerebral vasoconstriction frequently associated with focal cerebral ischaemia. The syndrome has been described in a variety of clinical conditions, and recently an association between the syndrome and exposure to vasoactive drugs was observed. Effective treatment options are not known. A 63-year-old female developed sudden 'worst ever' headache. Initial neurological examination, laboratory blood tests, CSF examination and brain magnetic resonance imaging (MRI) were normal. Previous medical history was unremarkable and she did not take vasoactive drugs. Eleven days after the onset of headache she developed visual field impairment and a right-sided hemiparesis. brain MRI revealed bilateral posterior and left parietal ischaemic strokes. Cerebral catheter angiography showed segmental arterial vasoconstriction. A vasodilative therapy with calcium channel inhibitors was started and serial transcranial Doppler ultrasonography demonstrated resolution of cerebral arterial vasoconstriction. The present case illustrates that calcium channel inhibitors may be an effective therapy for segmental cerebral arterial vasoconstriction. However, more clinical data are needed to prove this observation.

4/14. angioplasty and coiling of ruptured aneurysm with symptomatic vasospasm: technical case report.

    BACKGROUND: Treating a ruptured cerebral aneurysm during symptomatic vasospasm is very difficult. We describe the successful endovascular treatment of such a case and discuss its efficacy. CASE PRESENTATION: A 34-year-old man had a sudden onset of severe headache. One week later, he was referred to our institute with gradually progressing right hemiparesis and global aphasia. cerebral angiography demonstrated severe vasospasm of the left internal carotid artery system and an anterior communicating artery aneurysm. With the patient under general anesthesia, 90% occlusion of the aneurysm was achieved with detachable coils after successful dilatation of the spastic vessels. The patient had an uneventful postoperative course and his neurologic symptoms were improved. Seven months after the endovascular treatment, the enlarged neck remnant of the aneurysm was successfully clipped without difficulty. CONCLUSION: The simultaneous treatment of a ruptured aneurysm and vasospasm with percutaneous transluminal angioplasty and coils can produce a better outcome for the patient.

5/14. Posterior encephalopathy with vasospasm: MRI and angiography.

    Posterior encephalopathy is characterised by headache, impairment of consciousness, seizures and progressive visual loss. MRI shows bilateral, predominantly posterior, cortical and subcortical lesions with a distribution. Our aim was to analyse the MRI lesion pattern and angiographic findings because the pathophysiology of posterior encephalopathy is incompletely understood. We report three patients with clinical and imaging findings consistent with posterior encephalopathy who underwent serial MRI including diffusion-weighted imaging (DWI) and construction of apparent diffusion coefficient (ADC) maps, and four-vessel digital subtraction angiography (DSA). DWI revealed symmetrical subcortical and cortical parieto-occipital high signal. High and also low ADCs indicated probable vasogenic and cytotoxic oedema. On follow-up there was focal cortical laminar necrosis, while the white-matter lesions resolved almost completely, except in the arterial border zones. DSA revealed diffuse arterial narrowing, slightly more marked in the posterior circulation. These findings suggest that posterior encephalopathy may in some cases be due to diffuse, severe vasospasm affecting especially in the parieto-occipital grey matter, with its higher vulnerability to ischemia. Cerebral vasospasm due to digitoxin intoxication, resulting in posterior encephalopathy, has not yet been described previously.

6/14. Bathing headache: a variant of idiopathic thunderclap headache.

    Bathing headache is rarely described in literature. We report four middle-aged Taiwanese women who developed severe throbbing headache with maximum intensity of onset during bathing. Diffuse cerebral vasospasm was demonstrated in one of them. All their headaches resolved spontaneously (n = 1) or after nimodipine treatment (n = 3). Except for one patient with vasospasm in whom reversible posterior leukoencephalopathy and an asymptomatic cerebellar infarction developed, the others recovered without any complications. The clinical profile of bathing headache points to idiopathic thunderclap headache. It may not be as benign as previously reported. nimodipine might be effective in treatment of this special headache syndrome.

7/14. Development and rupture of a de novo basilar artery aneurysm after surgical removal of a cerebellar arteriovenous malformation.

    BACKGROUND: The de novo development of an aneurysm in an previously normal artery is an uncommon event. We describe a patient who developed a de novo bleeding aneurysm of the basilar artery in the three weeks following the surgical removal of a large cerebellar AVM. METHOD-FINDINGS: A 48-year-old man suddenly developed transient headache, vertigo and disturbance of balance. Neuroradiological examinations showed the presence of a large AVM of the right cerebellar hemisphere. The AVM was removed successfully; following the operation there were repeated bleeding episodes at the operating site, requiring surgical evacuation. Three weeks after the AVM removal he suffered from a massive subarachnoid haemorrhage due to the rupture of an aneurysm developed de novo in the basilar artery. INTERPRETATION: This is the first reported case, to our knowledge, of a de novo aneurysm developed in an artery hemodynamically related to a surgically removed AVM. This complication was probably due to the postoperative hemodynamic changes in the vessels afferent to the AVM, associated with arterial wall dysplasia.

8/14. Cerebral vasospasm and headache during sexual intercourse and masturbatory orgasms.

    BACKGROUND: The pathophysiology of the explosive type of headache associated with sexual activity is not completely understood. Five reported cases of patients with thunderclap headache, precipitated by sexual activity, in association with concomitant cerebral arterial narrowing, were found in the literature. methods: A 44-year-old woman with both coital and masturbatory headaches during orgasm associated with segmental reversible cerebral artery vasospasm was investigated. Cerebral anatomy and eventual spasm was documented by magnetic resonance imaging or digital angiography before, during, and after resolution of the orgasmic headache-vasospasm clinical manifestation. CONCLUSION: Findings of cerebral arterial narrowing, presented by some patients shortly after orgasmic headache attacks, support the hypothesis that segmental vasospasm may exert a role in the pathogenesis of this uncommon type of headache. The literature is reviewed, and possible mechanisms underlying the development of orgasmic headache are discussed.

9/14. Orgasmic headache with transient basilar artery vasospasm.

    A 36-year-old man without significant past medical history presented with recurrent explosive headache at the time of orgasm. magnetic resonance angiography showed focal mid-basilar artery narrowing. Despite receiving no specific therapy, the patient's headaches and vascular narrowing had resolved completely on follow-up six months later. While a number of pharmacologic agents have been proposed to be of benefit in orgasmic headache, this case suggests that spontaneous resolution may also occur.

10/14. cerebral infarction following pituitary apoplexy--case report.

    A 29-year-old man presented with lethargy, headache, high fever, and visual disturbance. Neurological examination showed mydriatic pupil, ptosis, diminished light reflex, and ophthalmoplegia on the left. Magnetic resonance (MR) imaging showed the typical findings of pituitary apoplexy, and cerebral angiography disclosed mild narrowing of the A1 segment of the left anterior cerebral artery (ACA). Transsphenoidal tumor resection was performed. Transient severe right hemiparesis occurred directly after the operation. Computed tomography demonstrated cerebral infarction in the territory of the left Heubner's and medial lenticulostriate arteries. pituitary apoplexy followed by cerebral infarction is very rare. Vasospasm of the perforating arteries of the ACA probably caused the cerebral infarction. Subarachnoid blood or vasoactive agents released from the tumor were the most likely cause of the vasospasm. MR imaging findings of contrast enhancement around the vessels may indicate reactive processes around the vessels.
