OBJECTIVE Despite widespread use of lumbar spinal fusion as a treatment for back pain, outcomes remain variable. Optimizing patient selection can help to reduce adverse outcomes. This literature review was conducted to better understand factors associated with optimal postoperative results after lumbar spinal fusion for chronic back pain and current tools(More)
In order to better delineate the profile of central actions of neuropeptide Y (NPY), the effects of intracerebroventricular administration of several doses (2.5-20 micrograms) of the peptide on spontaneous activity, muscular tone, body temperature, food intake, nociception and cataleptic manifestations were examined in rats. Results indicate that, starting(More)
Lymphoplasmacytic lymphoma is a chronic lymphoproliferative disorder characterized by a proliferation of plasma cells, small lymphocytes, plasmacytoid lymphocytes and the production of monoclonal IgM. Primary central nervous system lymphomas (PCNSL) are rare non-Hodgkin lymphomas (NHL) that can be found in the brain, leptomeninges, eyes or spinal cord, and(More)
 Pseudotumor cerebri (PTC) patients exhibit clear clinical signs and symptoms of higher intracranial pressure (ICP) without ventricular enlargement or mass lesions. The clinical picture of patients with PTC can sometimes be similar to that of Chiari Malformation type I (CMI). There is some evidence that Chiari I malformation and PTC may(More)
BACKGROUND This article illustrates, summarizes, and reviews the multifaceted application of four-dimensional (4D) computed tomography angiography (CTA) in the characterization and diagnosis of various cerebrovascular and tumor-associated vascular pathologies through the presentation of clinical cases, including acute and chronic stroke, arteriovenous(More)
The risks associated with unruptured intracranial aneurysms can be neurologically debilitating and even fatal. Evaluation of these aneurysms is critical for determining what type of intervention is warranted, if at all. Cerebral angiography has long been the gold standard in the evaluation of intracranial aneurysms. However, this diagnostic modality is(More)
Thirty-seven-year old female with hydrocephalus managed by a ventriculoatrial (VA) shunt presented with upper body edema, dysphagia, and headache. Imaging demonstrated thrombosis of the superior vena cava (SVC). Direct catheter thrombolysis led to resolution of thrombus burden. Superior vena cava thrombosis is a rare consequence of VA shunting and must be(More)
A 52-year-old man with a seven-year history of progressive weakness, gait problems, and pain in his extremities presented with subacute worsening of his symptoms. Examination revealed weakness in all four extremities, increased tone, hyperreflexia, and sensory deficits. MRI of the cervical spine showed an area of signal abnormality and abnormal enhancement(More)
