Vertebral artery dissections (VADs) comprise about 2% of ischemic strokes and can be associated with trauma, chiropractic manipulation, motor vehicle collisions, whiplash, amusement park rides, golfing, and other motion-induced injuries to the neck. We present a case of bilateral extracranial VAD as a complication of conducting an orchestra. To our knowledge, this has not been documented in the literature. Conceivably, vigorous neck twisting in an inexperienced, amateur conductor may place excessive rotational forces upon mobile portions of the verterbral arteries, tear the intima, deposit subintimal blood that extends longitudinally, and cause neck pain and/or posterior fossa ischemic symptoms. Magnetic resonance angiography examinations of axially oriented slices of bilateral VADs resemble the face of an ostrich. This observation is similar to the "puppy sign," in which bilateral internal carotid artery dissections resemble the face of a dog. Craniocervical dissections of either the carotid or vertebral arteries have the potential to form an aneurysm, cause artery-to-artery embolism, or completely occlude the parent artery, resulting in an ischemic stroke. Because bilateral VADs in axial magnetic resonance angiographic sections stand out like the eyes of an ostrich, and because the fast identification of VADs is so critical, we eponymize this image the "ostrich sign."

We report a young woman with sudden and severe retroorbital headache, neck pain, and a large sellar mass extending to the suprasellar cistern. A presumptive diagnosis of non-secreting pituitary macroadenoma undergoing apoplexy was made and transphenoidal surgery performed. Histopathology revealed mononuclear infiltration and marked non-hemorrhagic necrosis of the anterior pituitary consistent with a diagnosis of necrotizing infundibulo-hypophysitis. The possible pathogenesis of this rare variant of hypophysitis is discussed.

Carotid artery dissection, one of the most common causes of stroke in patients younger than 40 years of age, may develop spontaneously or after trauma. In 85% of cases, central neurological signs such as stroke, transient ischemic attack and amarozis fugax are seen, while headache and cranial nerve paralysis can be the presenting symptoms in the rest of cases. In this case report, a 35-year of age young male patient who had a progressive carotid artery dissection accompanied by complaints of left sided tinnitus and ipsilateral head and neck pain. The patient was admitted to the clinic with the diagnosis of carotid artery dissection and cerebral angiography (CA) was planned. During the CA performed the day after, three stents were placed in the dissection area. Improvement was observed in all complaints of the patient who was followed up in the clinic for 10 days. The patient was discharged in a healthy condition to return after three months for a control.

Spinal epidural hematoma is an accumulation of blood in the epidural space that can mechanically compress the spinal cord. It is an uncommon condition, and most cases occur spontaneously. Detailed evaluation of neurologic deficit and detailed history taking are important tools for early diagnosis, and magnetic resonance imaging is currently the diagnostic method of choice. Prompt surgical intervention is important in achieving positive clinical outcomes. Spinal epidural hematoma usually comes with acute, severe pain with radiation to the extremities and may be accompanied with severe neurologic deficit. Common neurologic signs include paraparesis and quadriparesis. Here, we report 2 cases of cervical spinal epidural hematoma with sudden onset of neck pain, followed by the development of unilateral limbs weakness and respiratory distress. Both patients were initially suspected to have acute ischemic stroke and were considered using intravenous thrombolytic therapy with recombinant tissue plasminogen activator as treatment. Cervical spinal epidural hematoma was confirmed after obtaining magnetic resonance imaging. Patients with this uncommon presentation must be carefully distinguished from acute stroke. This article aimed to highlight the potential pitfalls in diagnosing acute hemiparesis with no cranial nerves deficits and the importance of clinical suspicion.

Bilateral abducens nerve palsy is an unusual clinical presentation, which could be caused by stroke, aneurysm, trauma and malignant neoplasm. We describe here a patient with bilateral abducens nerve palsy caused by large B cell lymphoma originated from clivus. An 83-year-old woman admitted to our hospital because of diplopia and severe posterior neck pain. Her diplopia developed one month before and progressed to her admission. Neurological examination revealed bilateral abducens nerve palsy. Brain MRI with enhancement lesion in the clivus, suggesting that bilateral petroclival segment of the abducens nerves were affected by the lesion. Biopsied was performed via a transsphenoidal approach, and histological diagnosis was made as diffuse large B cell lymphoma. She received oral corticosteroid administration combined with radiation therapy. After initiation of the treatment, posterior neck pain was resolved and tumor size was reduced in the repeated brain MRI. However, diplopia and bilateral abducens nerve palsy were still unresolved. Although malignant lymphoma originated at the clivus is uncommon, according to a presenting case as well as previously reported cases, lymphoma can present as an isolated involvement in the clivus associated with headache, and bilateral abducens nerve palsy. It is suggested that the clivus tumor affected the petroclival segment of abducent nerve in our case.

Although carotid and vertebral (cervical) arterial dissections are not common presentations to the emergency department, timely and appropriate diagnostic strategies will allow early initiation of effective treatment therapies. Cervical arterial dissection occurs when the intimal wall of an artery is damaged as a result of trauma or defect. As blood fills the layers of the arterial wall, thrombi form, which can lead to stroke, pseudoaneurysm, vessel occlusion, and stroke. Intracranial dissections may result in subarachnoid hemorrhage. Because cervical arterial dissections may present with common signs and symptoms such as headache, neck pain, neurological deficits, and stroke, it is essential that dissection be considered early and ruled out quickly. Computed tomographic angiography, magnetic resonance angiography, and digital subtraction angiography may be used for diagnosis. Anticoagulation or antiplatelet therapy is the mainstay of treatment for spontaneous or traumatic dissections and will reduce the risk of stroke. Endovascular therapy or surgery may be indicated. Recurrence or rebleeding is a significant risk and must be managed.

Focal common carotid artery intramural haematomas are rare. A 50-year-old man with a spontaneous onset of tenderness in the region of the right common carotid artery presented to our hospital (Christchurch, New Zealand). Ultrasound and CT imaging were consistent for an intramural haematoma. He was treated with antiplatelet therapy. A follow-up MRA showed resolution of the haematoma. Focal common carotid artery intramural haematomas are rare but not to be overlooked. This case presents a cause for intractable spontaneous neck pain in the region of the common carotid artery. Given the risk of rupture through the intima and potential risk for stroke the current recommended treatment is controversial.

A 30-year-old woman with severe preeclampsia presented at 27 weeks of amenorrhea with left headache, neck pain, blurred vision and numbness of left hemiface that resolved spontaneously within 2 hours. A week later, hypertension remained poorly controlled despite combination of nicardipine and labetalol intravenous therapy; an urgent caesarean section was eventually performed due to onset of HELLP syndrome. At day 5 postpartum, the patient had a Horner syndrome with right ipsilateral disabling tinnitus. A CT-angiography of supra-aortic trunks was performed urgently; it showed a bilateral carotid arterial dissection without stroke, which was subsequently confirmed by MRI angiography. The patient was transferred in neurovascular intensive care unit. Anticoagulant therapy was implemented to prevent cerebral and retinal ischemic lesions. Symptoms resolved quickly and the patient was discharged at day 7 postpartum. MR-angiography performed 4 months later showed a full resolution of the bilateral carotid dissection. Anticoagulant therapy was therefore discontinued.

Vertebral artery dissection(VAD)presenting as isolated occipital headache and/or neck pain is being increasingly diagnosed because of the development of magnetic resonance imaging(MRI). While a majority of the patients diagnosed with this condition shows a favorable prognosis, the pain may be a predictor of fatal stroke in some patients. We aimed to find out the features of headache with VAD, identify the clinical manifestations indicative of VAD, and determine the ideal diagnostic approach to this condition to avoid fatal stroke. We reviewed medical records of 41 consecutive patients who showed VAD with isolated headache and were diagnosed between 1995 and 2008. All patients experienced pain in the occipitocervical area ipsilateral to the affected VA. Pain showed a sudden onset in 21(51%)patients, was persistent over several days in 31(76%)patients, and was severe enough to disable daily life activities in 34(83%)patients. Progression of stenosis or aneurysmal dilatation of the vessel was identified on follow-up imaging(angiography, magnetic resonance angiography)in 7 patients(17%), and was found within 14 days after pain onset in 6 of these patients(86%). Patients with persistent, severe, and unilateral pain in the occipitocervical area should undergo MRI examination, including surface anatomy scanning(SAS)imaging, and the possibility of VAD should be considered in their diagnosis. Once VAD is diagnosed, the patient should undergo meticulous blood pressure control, bed rest, and repeated MRI examination for at least 2 weeks after onset.

Vertebral artery (VA) dissecting aneurysm (VADA), which presents with headache and neck pain as the only manifestations, is an uncommon pathology, but is increasingly recognized as a cause of posterior circulation stroke in young adults. We report a case of VADA with isolated occipital headache at the time of onset and treatment using an endovascular approach. A 58-year-old man was admitted to our hospital with left occipital headache. Cranial magnetic resonance imaging (MRI) showed neither subarachnoid hemorrhage(SAH)nor cerebral infarction, but magnetic resonance angiography (MRA)revealed left VADA. Conservative treatment including pain relief and blood pressure control was provided. After 2 weeks, the dissecting lesion showed spontaneous improvement and occipital headache was gradually improving. However, 4 months after onset, the VADA showed growing aneurysmal dilatation. We therefore performed endovascular surgery (coil embolization with parent artery occlusion). Symptoms improved, and the postoperative course was uneventful. Although the natural history of VADA with isolated headache remains unclear, endovascular treatment should be considered for patients with growing aneurysmal dilatation, since the prognosis for patients with subsequent SAH is very poor.
