Extranodal lymphomas constitute 20% to 30% of all non-Hodgkin's lymphomas. The common sites involved are skin, stomach, brain, and small intestine. Epidural localization is a rare site for lymphomas, accounting for 10% of spinal epidural tumors. Lymphomas occurring primarily in the epidural space without other previously detected lymphomatous foci (i.e., primary spinal epidural lymphomas) repre...

220 July 2016 P mediana dorsalis (PMD) has been rarely visualized but is occasionally implicated as a cause of unilateral epidural local anesthesia. Herein, we demonstrate PMD using epidurography. a normal anteroposterior epidurogram should show contrast outlining the lateral margins of the epidural space bilaterally.1 Herein, we show a unilateral epidurogram through a midline epidural catheter...

STUDY DESIGN A multicenter, retrospective analysis of cervical epidurograms. OBJECTIVES To determine the effectiveness of the loss of resistance (LOR) technique in identifying the cervical epidural space. To delineate the pattern of epidural contrast spread during cervical epidural steroid injections. BACKGROUND Previous studies have shown that if performed without fluoroscopy, the LOR tech...

Cavernous hemangiomas affect mainly the brain and infrequently they are located in the intramedullary space. Spinal epidural cavernous haemangiomas are extremely rare and are mainly located to the cervico-thoracic spine. It is infrequently considered in the differential diagnosis of spinal epidural masses. We report a rare case of a cavernous haemangioma confined to the lumbar spinal epidural s...

Background. Extraosseous Ewing's sarcoma in the spinal epidural space is a rare malignancy, especially in adults. Case Presentation. A 40-year-old male presented with back pain and urinary hesitancy. MRI revealed a thoracic extradural mass with no osseous involvement. He underwent surgery for gross total resection of the mass, which was diagnosed as Ewing's sarcoma. He was subsequently treated ...

The amount of pressure exerted on the syringe and the depth of needle insertion are the two key factors for successfully carrying out epidural procedure. The force feedback from the syringe plunger is helpful in judging the loss of pressure, and the depth of the needle insertion is crucial in identifying when the needle is precisely placed in the epidural space. This article presents the develo...

BACKGROUND Incorrect placement of epidural catheters causes medical complications. We used linear discriminant analysis (LDA) to develop an intelligent recognition system (i-RS) in order to guide epidural placement and reduce physician error. METHODS We analysed real-time dual-wavelength fibreoptic data recorded from the end of an epidural needle in a live porcine model. Two categories of tis...

This review aims to report an update on drugs administered into the epidural space for anesthesia and analgesia in dogs, describing their potential advantages and disadvantages in the clinical setting. Databases searched include Pubmed, Google scholar, and CAB abstracts. Benefits of administering local anesthetics, opioids, and alpha2 agonists into the epidural space include the use of lower do...

BACKGROUND Epidural anaesthesia is one of the most commonly used locoregional techniques in ruminants. The lumbosacral epidural technique is reasonably easy to perform and requires low volumes of local anaesthetic drug to allow procedures caudal to the umbilicus. However, surgical procedures in the flank of the animal would require an increased volume of drugs. The anaesthetized area provided b...

Epidural analgesia has widespread use in infants and children for postoperative pain management and for certain chronic pain conditions such as cancer pain and complex regional pain syndrome. While epidurals can provide excellent analgesia in pediatric patients, they do require specific expertise in both the techniques of placement and in the management. Pediatric-specific protocols and guideli...
