1/78. Compression of the visual pathway by anterior cerebral artery aneurysm.Visual failure is an uncommon presenting symptom of an intracranial aneurysm. It is even more uncommon in aneurysms arising from the anterior cerebral artery (ACA). We presented 2 patients with an aneurysm of the A1 segment of the anterior cerebral artery causing visual field defects. One patient presented with a complete homonymous hemianopia due to compression of the optic tract by a giant aneurysm of the proximal left A1 segment. The second patient had an almost complete unilateral anopia caused by compression of the optic nerve and chiasm by an aneurysm of the distal part of the A1 segment with a small chiasmatic hemorrhage and ventricular rupture.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/78. Lumbar spinal subdural hematoma following craniotomy--case report.A 52-year-old female complained of lumbago and weakness in the lower extremities 6 days after craniotomy for clipping an aneurysm. Neurological examination revealed symptoms consistent with lumbosacral cauda equina compression. The symptoms affecting the lower extremities spontaneously disappeared within 3 days. Magnetic resonance (MR) imaging 10 days after the operation demonstrated a lumbar spinal subdural hematoma (SSH). She had no risk factor for bleeding at this site, the symptoms appeared after she began to walk, and MR imaging suggested the SSH was subacute. Therefore, the SSH was probably due to downward movement of blood from the cranial subdural space under the influence of gravity. SSH as a complication of cranial surgery is rare, but should be considered if a patient develops symptoms consistent with a lumbar SSH after craniotomy.- - - - - - - - - - ranking = 0.11111111111111keywords = aneurysm (Clic here for more details about this article) |
3/78. Double vision in a child.A 10-year-old boy presented with a complete left oculomotor cranial nerve palsy. Diagnostic evaluation, including neuroimaging and cerebral angiography revealed a small intracranial aneurysm compressing the third nerve. Neurosurgical clipping of the aneurysm produced resolution of the third nerve palsy. The rarity of this presentation in a young patient is discussed, along with the importance of rapid diagnosis and treatment.- - - - - - - - - - ranking = 0.22222222222222keywords = aneurysm (Clic here for more details about this article) |
4/78. Anchoring method for hemifacial spasm associated with vertebral artery: technical note.OBJECTIVE: We describe an easy and useful method for treating hemifacial spasm related to the vertebral artery. methods: The technique entails the manufacture of a dural belt harvested from the cerebellar convexity dura and a dural bridge made at the petrous dura combined with the use of an aneurysm clip. The dural belt holds the vertebral artery and is anchored to the dural bridge by fixation with an aneurysm clip after the vertebral artery is transposed to an appropriate position. RESULTS: The technique proved to be safe and effective in a series of six patients with hemifacial spasm who were followed up for a period of 2 months to more than 10 years after surgery. All patients were affected on the left side. Multiple offending arteries were present in three cases. hemifacial spasm completely disappeared in all patients. CONCLUSION: This method represents a feasible option for the treatment of hemifacial spasm caused by a tortuous, elongated, or enlarged vertebral artery.- - - - - - - - - - ranking = 0.22222222222222keywords = aneurysm (Clic here for more details about this article) |
5/78. Late-onset isolated gelastic epilepsy secondary to entrapment of the right temporal horn.The case is reported of a 70 year-old woman with isolated gelastic seizures (GS) secondary to a rare form of focal obstructive hydrocephalus, called entrapment of the lateral horn. Laughing attacks started five years after conservative intracranial surgery for a giant basilar aneurysm. Serial neuro-imaging studies revealed a progressive cystic enlargement of the right temporal horn, damaging the baso-lateral temporal cortex. An ictal EEG recording confirmed the epileptic nature of laughing attacks, and showed that the epileptiform activity originated in the right temporal lobe. Complete seizure control was achieved with current doses of diphenilhydantoin. Analysis of this and other previously reported cases, indicate that symptomatic GS may originate in multiple sites of both cerebral hemispheres, although related to the limbic system. The fact that this case exhibited isolated GS stresses the importance of the baso-lateral temporal cortex in the genesis of this type of seizures.- - - - - - - - - - ranking = 0.11111111111111keywords = aneurysm (Clic here for more details about this article) |
6/78. Remission of hemifacial spasm after proximal occlusion of vertebrobasilar dissecting aneurysm with coils: case report.intracranial aneurysm is a rare cause of hemifacial spasm and most of the previously reported cases are treated with surgical microvascular decompression. Authors report a case of hemifacial spasm caused by a dissecting aneurysm located at the vertebrobasilar junction which improved after endovascular obliteration of the affected vertebral artery with coils.The patient was a 69-year-old man with 20 months' history of left hemifacial spasm. A vertebral angiogram showed an irregular dilatation of the right vertebral artery associated with aneurysmal dilatation at the vertebrobasilar junction. Endovascular obliteration of the abnormally dilated right vertebral artery proximal to the vertebrobasilar junction was performed. The hemifacial spasm gradually improved after the embolisation and disappeared 6 months later. Endovascular proximal obliteration of the vertebral artery may have changed the hemodynamic force inside the aneurysm and eliminated the vascular compression at the root exit zone of the facial nerve.- - - - - - - - - - ranking = 0.88888888888889keywords = aneurysm (Clic here for more details about this article) |
7/78. median nerve compression caused by a venous aneurysm. Case report.A rare case of peripheral-nerve compression in the upper arm caused by a spontaneous venous aneurysm is reported. The apparent dysfunction of the median nerve led to various vain surgical explorations of the nerve at different levels. The real localization of nerve entrapment was identified by a thorough clinical examination, and sonography yielded a correct diagnosis. Surgical resection of the venous aneurysm resulted in complete relief of pain. To the authors' knowledge, this is the first report of a spontaneous venous malformation in the upper arm causing focal neuropathy.- - - - - - - - - - ranking = 0.66666666666667keywords = aneurysm (Clic here for more details about this article) |
8/78. brain stem compression by a giant vertebrobasilar aneurysm mimicking seronegative myasthenia.A patient is described with a vertebrobasilar aneurysm who was erroneously thought to have myasthenia gravis on the basis of the clinical presentation and investigations, which were interpreted as supportive of a disorder of the neuromuscular junction. Despite the correct diagnosis being made at a late stage the patient made a full recovery after radiological intervention.- - - - - - - - - - ranking = 0.55555555555556keywords = aneurysm (Clic here for more details about this article) |
9/78. A spontaneous ductal aneurysm presenting with left recurrent laryngeal nerve palsy.A 76-year-old man was found to have a left recurrent laryngeal nerve palsy, due to a spontaneous patent ductus arteriosus aneurysm. Ortner's syndrome (left recurrent laryngeal nerve palsy caused by cardiovascular pathology) secondary to patent ductus arteriosus aneurysm has not previously been described in the literature. We present a case, illustrated with surface rendering computer tomogram reconstructions.- - - - - - - - - - ranking = 0.66666666666667keywords = aneurysm (Clic here for more details about this article) |
10/78. A huge osteoblastoma with aneurysmal bone cyst in skull base.We reported a case of a huge osteoblastoma in the skull base of a young girl who had developed blindness in her right eye 1 year prior to examination. CT showed a large expansile bony lesion with eggshell margin over the skull base. MR imaging showed mixed solid and cystic parts with multiple fluid-fluid levels in the lesion. The optic chiasma and bilateral optic nerves were severely compressed by the tumor.- - - - - - - - - - ranking = 0.44444444444444keywords = aneurysm (Clic here for more details about this article) |
