Meningeal melanocytoma is a rare benign CNS tumor derived from the leptomeningeal melanocytes. Although unusual, malignant transformation with leptomeningeal seeding into the brain or spinal cord may occur years after the initial diagnosis. The authors report a unique case of multifocal benign meningeal melanocytoma involving both cerebellopontine angles(More)
Korsakoff-like amnestic syndromes have been rarely described following structural lesions of the central nervous system. In this report, we describe a case of acute Korsakoff-like syndrome resulting from the combination of a left anteromedian thalamic infarct and a right hippocampal hemorrhage. We also review the literature relevant to the neuropathology(More)
Trigeminal neuralgia has been rarely reported in association with dural arteriovenous malformations (DAVMs). We describe a case of trigeminal neuralgia resulting from compression of the trigeminal nerve at its root entry zone by a large tentorial DAVM. Surgical interruption of the draining vein at its exit from the tentorium resulted in complete(More)
OBJECTIVE To analyze the impact of the lunar cycle and season on the incidence of aneurysmal subarachnoid hemorrhage (SAH). PATIENTS AND METHODS The medical records of 111 patients who were admitted over a 5-year period to our department because of aneurysmal SAH were retrospectively reviewed. The date of aneurysm rupture was matched with the(More)
OBJECT Radiofrequency (RF) ablation is a minimally invasive technique often used percutaneously in the treatment of many conditions such as spasticity, pain, and osteoid osteoma. The purpose of this study was to assess the value of motor response threshold (MRT) as an indirect indicator of the RF generator's electrode to nerve distance, and to evaluate the(More)
INTRODUCTION Brucellosis is a rare disease in which neurological complications, and more particularly, intracranial aneurysmal hemorrhages were rarely reported. CASE REPORT A brucellar meningitis was diagnosed in a 29-year-old man, who had been suffering from an unusual headache for about two months. Three days after beginning treatment, the patient(More)
Spinal epidural hematomas (SEHs) are rare complications following spine surgery, especially for single level lumbar discectomies. The appropriate surgical management for such cases remains to be investigated. We report a case of an extensive spinal epidural hematoma from T11-L5 following a L3-L4 discectomy. The patient underwent a single level L4. A(More)
INTRODUCTION Brucellosis is a rare disease with variable neurological and imaging manifestations. CASE REPORT A 54-year-old woman presented with progressive paraparesis and sensorineural hearing loss over 18 months. The presence of diffuse white matter changes on brain magnetic resonance imaging (MRI) and cerebrospinal fluid findings led to the diagnosis(More)
Hydrocephalus resulting from bilateral thrombosis of the jugular veins has been rarely described in the literature. We report the case of an 18-month-old girl who was diagnosed with this condition following total parenteral nutrition. We also review the literature relevant to this subject and discuss the pathophysiology of hydrocephalus in the setting of(More)
