BACKGROUND Magnetic resonance imaging is a diagnostic tool of growing importance. Since its introduction, certain medical implants, e.g., pacemakers, were considered an absolute contraindication, mainly due to the presence of ferromagnetic components and the potential for electromagnetic interference. Patients with such implants were therefore prevented(More)
We describe a patient who was in a stupor for several days after combined general-spinal anesthesia. Both clinical manifestations and magnetic resonance imaging findings were consistent with posterior reversible encephalopathy syndrome and resolved after the patient recovered spontaneously.
One of the key aspects of creativity is the ability to produce original ideas. Originality is defined in terms of the novelty and rarity of an idea and is measured by the infrequency of the idea compared to other ideas. In the current study we focused on divergent thinking (DT) - the ability to produce many alternate ideas - and assessed the neural pathways(More)
Posterior fossa mass lesions in children usually present a diagnostic challenge despite their high frequency and the limited number of differential diagnostic possibilities. Consideration of medulloblastoma within the differential diagnosis of such lesions mandates an aggressive surgical approach as residual tumor is a known risk factor for poor prognosis.(More)
Rhabdoid meningioma is an aggressive phenotype of meningioma, associated with a poor prognosis. We present a very rare case of high-grade meningioma with rhabdoid features that eventually expressed in a coma state. Comprehensive genomic profiling using a Next Generation Sequencing (NGS) assay revealed three genomic alterations: activating BRAF mutation(More)
We studied three siblings, born to consanguineous parents who presented with severe intellectual disability, cachexia, strabismus, seizures and episodes of abnormal respiratory rhythm. Whole exome sequencing led to identification of a novel homozygous splice site mutation, IVS29-1G > A in the NALCN gene, that resulted in aberrant transcript in the patients.(More)
A 15-year-old boy was diagnosed with choroid plexus carcinoma (CPC) of the right lateral ventricle. His metastatic work-up was negative. After complete macroscopic resection of the tumor, the patient was treated with chemotherapy consisting of vincristine, cisplatin, etoposide, and carboplatin, followed by radiotherapy for a total dose of 34.2 Gy on the(More)
Aortic dissection masquerading as ischemic stroke is particularly challenging in the era of thrombolysis as a result of narrow diagnostic time window and severe hemorrhagic potential. We describe a case of a 77-year-old patient with a presumed ischemic cerebral infarct, in whom planned treatment with tissue plasminogen activator therapy (TPA) was withheld(More)
OBJECTIVES The purpose of this study was to determine the value of dynamic high-resolution sonography for evaluation of temporomandibular joint (TMJ) disk displacement compared to magnetic resonance imaging (MRI) with the mouth closed and during the maximal mandibular range of motion. METHODS Dynamic high-resolution sonography with the mouth closed and(More)
Background. Thalamotomy is effective in alleviating tremor in Parkinson's disease (PD). Methods. Seven PD patients, mean age 59.4 ± 9.8 years (range, 46-74) with a mean disease duration of 5.4 ± 2.8 years (range, 2-10) suffering from severe refractory tremor, underwent ventral intermediate nucleus thalamotomy using MRI guided focused ultrasound (MRgFUS), an(More)
