Syringomyelia is frequently associated with Chiari malformation or one of many other pathological conditions. Its co-occurrence with medulloblastoma is rare, and to our knowledge, only 4 patients have been reported, although some reports have documented on syringomyelia associated with intracranial processes or intramedullary tumor. The authors describe an unusual case of asymptomatic thoracic syringomyelia complicated by an intrasyringal hemorrhage in a child with medulloblastoma. This report illustrates that, although unusual, syringomyelia is a potential complication in the natural history of medulloblastoma, and the authors consider the possible pathogenesis of syrinx enlargement. 相似文献

Among cases of embryonic carotid-basilar anastomosis which may persist after birth, persistent trigeminal artery is the most common. It has been associated with a wide variety of intracranial abnormalities. We are unaware of any other reported association with cavernoma. We report a young woman who experienced seizures following spontaneous abortion. A CT scan disclosed a right frontal hematoma. MRI revealed a cavernoma associated with a persistent trigeminal artery. The cavernoma was removed through a frontal approach. The aim of the present case is to report another type of lesion fortuitously associated with a persistent trigeminal artery. 相似文献

Background and purpose
The WEB is an innovative flow disruption device for cerebral aneurysm embolization with rapidly expanding indications. Our purpose was to evaluate the diagnostic performance of computed tomography angiography (CTA) at 1-year follow-up of aneurysms treated with the WEB.Materials and methods
Between April 2014 and May 2016, the study prospectively included patients treated with the WEB at our institution, and followed up within 24 hours by CTA and at 1 year by CTA, time-of-flight magnetic resonance angiography (TOF MRA) and digital subtraction angiography (DSA). The diagnostic quality of imaging data was assessed based on the confidence index, artifacts, and WEB shape depiction. The imaging diagnostic performance was assessed using 3 criteria at 1 year: aneurysm occlusion status and worsening, and WEB shape compression. Interobserver and intermodality agreement was determined by calculating κ values.Results
The study ultimately included 16 patients (9 women, mean age 53 ± 7.6 years). CTA quality confidence was scored as 2/2, artifacts 0.4/2 and WEB shape depiction 1.9/2, superior to TOF MRA for the latter two criteria. Aneurysm occlusion was adequate in 93.7% of patients, with CTA showing excellent interobserver reproducibility and agreement with DSA on a 4-grade scale (κ = 1.00), while TOF MRA yielded good reproducibility (κ = 0.76) and agreement with DSA (κ = 0.69). CTA also identified aneurysm occlusion worsening (43.7%) and WEB compression (81.2%) in excellent agreement with DSA (κ = 0.85 and 1.00).Conclusions
CTA is a reproducible and reliable technique for the follow-up of aneurysms treated with the WEB device. 相似文献5.

Even if acute subarachnoid hemorrhage (SAH) accounts for only 5% of strokes, its diagnosis is very important because its clinical consequences can be tragic. Recent technological advances in medical imaging have improved diagnostic and therapeutic management of patients with SAH. Nonenhanced CT of the head is the initial imaging modality in suspected SAH for the detection of ruptured intracranial aneurysms. Digital subtraction angiography (DSA) remains the reference exam. Multidetector row CT angiography may potentially replace DSA in the emergency setting, as it provides image data that allows evaluating aneurysmal morphology, the neck size or the visualization of vessels in the vicinity of the aneurysm. For SAH unrelated to aneurysm rupture (15% of cases), MRI and MRA can be added to the diagnostic work-up in order to exclude other differential diagnoses such as venous thrombosis or angiitis. Finally, transcranial color-coded duplex sonography, CT, or MRI are used in clinical practice in order to detect aggravating factors of SAH like hydrocephalus or vasospasm. 相似文献

Between June 1987 and October 1989, nine patients with suspected Cushing's disease were explored by magnetic resonance imaging (MRI), using an 0.35 or 0.5 Tesla magnet. All these patients underwent transsphenoidal surgery and radio-surgical correlations could be established. MRI showed a lesion in 5 cases; it was negative in 2 cases and doubtful in 2 cases. Surgery was positive for pituitary adenoma in 7 cases and negative in 2 cases (including 1 patient with subsequently discovered paraneoplastic syndrome). Using sagittal and coronal planes and combined with gadolinium enhancement, MRI proved to be the most sensitive and specific of all exploratory methods for the diagnosis of ACTH-secreting pituitary adenomas. 相似文献

Summary The authors document a rapid development, within 3 weeks, of hydromyelia in a 12 year-old boy. The boy was admitted to a local
hospital because of drowsiness and persistent severe neck pain. Neurological examination disclosed a lethargic boy with no
neurological deficit other than Parinaud’s sign. During his transfer to our department, he presented a cardio-respiratory
arrest with coma and bilateral mydriasis. External ventricular drain and craniocervical decompression achieved excellent clinical
and neuroradiological outcomes. The development of hydromyelia in this case is caused by obstruction to the natural cerebrospinal
fluid pathway at the craniocervical junction and the cardio-respiratory arrest is provoked by a brain stem compression against
the clivus and odontoid process. This report illustrates that hydromyelia may complicate acute obstructive hydrocephalus due
to acquired Chiari malformation. 相似文献
