Wall motion at 4D-CT angiography and surgical correlation in unruptured intracranial aneurysms: a pilot study.

Background: Unruptured intracranial aneurysms (UIAs) are reported more frequently nowadays but their management is not well established; it depends on different structural features of the aneurysms and on multiple patient's risk factors. With this prospective observational study we report our preliminary experience by using four-dimensional (4D) computed tomographic (CT) angiography with ECG-gated reconstructions in the evaluation of dynamic modifications of the aneurysm wall, as a potential predicting factor of growth or rupture. The novelty of this study consists in the correlation between Angio 4D-CT angiography images and surgical findings; only few scientific papers, in fact, have studied this issue.

Ophthalmoplegic migraine: from questions to answers.

Introduction: The International Classification of Headache Disorders classifies ophthalmoplegic migraine (OM) under "cranial neuralgias and central causes of facial pain." OM is diagnosed when all the following criteria are satisfied: A. At least two attacks fulfilling criterion B.

Cavernous sinus apoplexy presenting isolated sixth cranial nerve palsy: case report.

The clinical and radiological findings of a patient affected by apoplexy of an adenoma located within cavernous sinus and presenting isolated Cranial Nerve (CN) VI palsy are reported. The differential diagnosis with other pathologies is debated, and pathogenesis of isolated abducens nerve palsy is investigated. The pertinent literature of this uncommon case of apoplexy is reviewed.

Computed tomography and magnetic resonance imaging findings in ophthalmoplegic migraine.

A patient with ophthalmoplegic migraine is described, and his computed tomography and magnetic resonance imaging findings are discussed. According to our results, triad migraine, third nerve palsy, and focal enhancement of an enlarged third cranial nerve at the root exit zone should be considered pathognomonic of the disease, and further examinations should be avoided. Pathogenetic theories of the disease are discussed, and we suggest a new pathogenetic theory.

A combined a-EEG and MR spectroscopy study in term newborns with hypoxic-ischemic encephalopathy.

Objectives: Brain damage following a perinatal hypoxic-ischemic (HI) insult has been documented by different diagnostic techniques. The aim of the present study was to relate a-EEG time course during the first 24h of life to brain metabolic changes detected by proton MR spectroscopy ((1)H-MRS) at 7-10days of life and to evaluate their correlation with outcome.

Methods: Thirty-two patients with any grade HI encephalopathy were studied.

Anterior spinal artery syndrome complicated by the ondine curse.

Background: Anterior spinal artery (ASA) syndrome results in motor palsy and dissociated sensory loss below the level of the lesion, accompanied by bladder dysfunction. When the cervical spine is involved, breathing disorders may be observed.

Objective: To describe the polysomnographic findings in a patient with cervical ASA syndrome complicated by a sleep breathing disorder.
