The epidural space is frequently used for placement of the epidural needle, catheter, and various pharmacological agents. The presence of structures in the epidural space such as epidural fat, venous plexus, or ligaments that may lead to uneven distribution of agents within the epidural space have been described.(1-3) Whether these structures are anatomical (such as connective tissue) or functional (due to distortions of actual anatomy secondary to injection of agents epidurally) has been disputed.(2-5) We describe our management of a patient who presented with bilateral radicular symptoms and severe low back pain...

BACKGROUND: For decades, epidural steroid injections have been an effective tool in the management of many pain related conditions, including lumbar radiculopathy. Transforaminal epidural steroid injections in particular have been reported to potentially result in central nervous system infarctions which have not been reported with interlaminar epidural steroid injections, while providing comparable efficacy. This rare, catastrophic complication has been attributed by some authors to be due to vascular injury secondary to vasospasm, thrombus formation, dissection, as well as concerns with placing the needle at the so-called "safe triangle...

INTRODUCTION: Spinal infarction accounts for 1% of all strokes. Cardioembolism is a rare cause. Common areas of ischemic spinal damage are watershed in the dorsal or lumbar regions; however cervical spinal cord infarction has been reported previously. CASE REPORT: We present a new case of a man-in-the-barrel syndrome produced by cardiac embolization associated with atrial fibrillation during an acute myocardial infarction, which caused cervical ischemic neuronopathy (infarction of the anterior horn)...

BACKGROUND AND PURPOSE: Spinal epidural AVFs are rare spinal vascular malformations. When there is associated intradural venous reflux, they may mimic the more common spinal dural AVFs. Correct diagnosis and localization before conventional angiography is beneficial to facilitate treatment. We hypothesize that first-pass contrast-enhanced MRA can diagnose and localize spinal epidural AVFs with intradural venous reflux and distinguish them from other spinal AVFs. MATERIALS AND METHODS: Forty-two consecutive patients with a clinical and/or radiologic suspicion of spinal AVF underwent MR imaging, first-pass contrast-enhanced MRA, and DSA at a single institute (2000-2015)...

BACKGROUND: Dentigerous cyst occurs in approximately 20% of jaw cysts, being the second major common odontogenic cyst, after radicular cyst. This oral lesion has the ability to destroy maxillary bones and could be the origin of several odontogenic tumors. However, molecules implicated in its pathogenesis as well as those involved in its neoplastic transformation remain unknown. Here, we established a cell population derived from a dentigerous cyst as an in vitro model for the study of this oral lesion...

Aortic pseudoaneurysm can create a constellation of symptoms that can mimic lumbar back pain. There are rare but well-documented reports of aortic pathology (aneurysms, pseudoaneurysms, and chronic contained aneurysm ruptures) eroding into the vertebral column causing neural compression. We report a case of a rapidly progressive aortic pseudoaneurysm in a patient with pre-existing lumbar spine pathology which had the potential for catastrophic intraoperative bleeding during a minimally invasive surgery (MIS) using the transforaminal lumbar interbody fusion (TLIF) technique...

BACKGROUND CONTEXT: In today's healthcare climate, Magnetic Resonance Imaging (MRI) is often perceived as a commodity - a service where there are no meaningful differences in quality and thus an area in which patients can be advised to select a provider based on price and convenience alone. If this prevailing view is correct, then a patient should expect to receive the same radiological diagnosis regardless of which imaging center he or she visits or which radiologist reviews the examination...

INTRODUCTION: The purpose of this study was to establish a stable experimental mice pulpal inflammatory model and to evaluate inflammatory reactions of pulpal tissue after pulpal exposure. METHODS: Pulpal inflammation was induced in 80 C57BL/6 mice by occlusal exposure of the pulp of the maxillary first molar. The mice were sacrificed randomly at 0, 1, 6, 12, 24, 48, and 72 hours after pulpal exposure. Mice without pulpal exposure served as controls. Maxillary teeth were obtained and prepared for histologic analyses and real-time polymerase chain reaction analyses...

INTRODUCTION: Spontaneous spinal epidural hematoma (SSEH) is an uncommon but potentially fatal condition. The increased bleeding tendency associated with anticoagulant medications has been proven to increase the risk of SSEH. The symptoms of SSEH usually begin with sudden severe neck or back pain and are followed by neurological deficits. However, some cases present with only axial pain or with radicular pain similar to herniated disc disorders. CASE PRESENTATION: A 28-year-old healthy man developed a sudden onset of severe neck and right shoulder pain with mild arm weakness...

BACKGROUND: Another rare cause of lower back pain with radiculopathy is the discal cyst. It is believed to arise from degeneration of a herniated disc, although many other theories of its origin have been proposed. Here, we report a patient with lower back pain/radiculopathy attributed originally to a herniated lumbar disc, which transformed within 6 months into a discal cyst. CASE DESCRIPTION: A 42-year-old male had a magnetic resonance (MR) documented herniated lumbar disc at the L4-5 level...
