INTRODUCTION: Hemangiomas are benign tumors characterized by proliferation of blood vessels. A few hemangiomas are aggressive, characterized by bone expansion and extraosseous extension. These benign tumors may be mistaken for metatasis resulting in unnecessary biopsies, which have a high risk of hemorrhage. These hemangiomas can spread not just into the paraspinal soft tissues but also into the epidural region of the spinal canal causing cord compression and paraparesis. These clinical symptoms can be relieved by surgical decompression of the posterior elements, embolization or radiotherapy...

Traumatic thoracolumbar burst fractures are one of the most common forms of spinal trauma with the majority occurring at the junctional area where mechanical load is maximal (AOSpine Thoracolumbar Spine Injury Classification System Subtype A3 or A4). Burst fractures entail the involvement of the middle column, and therefore, they are typically associated with bone fragment in the spinal canal, which may cause compression of the spinal cord, conus medullaris, cauda equina, or a combination of these. Fortunately, approximately half of the patients with thoracolumbar burst fractures are neurologically intact due to the wide canal diameter...

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: Current surgical management of degenerative spondylolisthesis (DS) involves decompression of the spinal canal followed by fusion with or without interbody. The additional functional and operative benefits derived from interbody inclusion has yet to be thoroughly established with a number of recent studies producing conflicting results. Thus, we aim to compare the functional and operative outcomes after fusion against interbody fusion in the treatment of DS...

The risk for spinal cord injuries (SCIs) ranging from devastating traumatic injuries, compression due to degenerative pathology, and neurapraxia is increased in patients with congenital spinal stenosis. Classical diagnostic criteria include an absolute anteroposterior diameter of <12-13mm or a Torg-Pavlov Ratio of <0.80-0.82; however, these factors do not take into account the size of the spinal cord, which varies across patients independent of canal size. Recent large MRI studies of population cohorts have allowed newer methods to emerge that account for both cord and canal size by measuring a spinal cord occupation ratio (SCOR)...

The diagnosis of decompression illness (DCI), which is based on a history of decompression and clinical findings, can sometimes be confounded with other vascular events of the central nervous system. The authors report three cases of divers who were urgently transported to a hyperbaric facility for hyperbaric oxygen treatment of DCI which at admission turned out to be something else. The first case, a 45-year-old experienced diver with unconsciousness, was clinically diagnosed as having experienced subarachnoid hemorrhage, which was confirmed by CT scan...

BACKGROUND: The lumbar spine includes 5 lumbar vertebral bodies, L1, L2, L3, L4, and L5. At each level, there is a disc space defined by the two bones (vertebral bodies) in the back; for example, there is a disc space at the L5-S1 level etc. The normal front to back (anterior to posterior or AP diameter) measurement of the spinal canal is typically 18-20 mm, but some patients have narrowing called spinal stenosis. METHODS: Lumbar stenosis is defined by two major types...

PURPOSE: Anterior approach to the upper thoracic spine is difficult. It is important for spine surgeons to know the indication and the effect of anterior decompression for upper thoracic lesions and also to recognize the complications which are related to the approach with sternotomy. We present two patients for whom we took the sternum-splitting anterior approach for thoracic ossification of the posterior longitudinal ligament (OPLL) following posterior decompression and fusion surgery; the clinical course and surgical outcome are discussed, with particular reference to complication avoidance and also we review the previous literature...

Ossification of the ligamentum flavum (OLF) may result in thoracic myelopathy (TM) because of the spinal canal narrowing. The aim of this study was to investigate clinical outcomes of symptomatic thoracic OLF treated using posterior decompressive laminectomy. We made a retrospective review of patients who underwent posterior decompressive laminectomy from 2007 through 2016 for symptomatic TM caused by OLF. Thirty-three patients who had surgery for TM caused by OLF that was diagnosed based on clinical, radiologic, and pathologic evaluations...

Orbital emphysema and associated pneumocephalus usually result from trauma to orbital bones or due to sinus disease, allowing air to travel from paranasal sinus into orbit and brain. However, it is extremely rare to have orbital emphysema and pneumocephalus in the absence of orbital wall fracture. In our case, a young male was admitted with severe eye pain, diminution of vision due to sudden exposure of compressed air gun. Examination revealed proptosed, emphysematous right eye with conjunctival laceration...

BACKGROUND CONTEXT: Although lumbar disc herniations are common, only a small portion of these herniations lead to cauda equina syndrome (CES) which is an uncommon but debilitating disorder. Why some patients with herniation develop CES, when most do not, remains unknown. Pre-existing subclinical epidural lipomatosis may limit canal space such that an otherwise benign herniation causes CES. PURPOSE: This study determines whether patients with an acute disc herniation and CES have a greater body mass index (BMI) and greater quantity of epidural fat compared to control subjects with non-CES symptomatic lumbar herniated discs...

The objective of this work is to automatically produce radiological gradings of spinal lumbar MRIs and also localize the predicted pathologies. We show that this can be achieved via a Convolutional Neural Network (CNN) framework that takes intervertebral disc volumes as inputs and is trained only on disc-specific class labels. Our contributions are: (i) a CNN architecture that predicts multiple gradings at once, and we propose variants of the architecture including using 3D convolutions; (ii) showing that this architecture can be trained using a multi-task loss function without requiring segmentation level annotation; and (iii) a localization method that clearly shows pathological regions in the disc volumes...

Indeterminate dendritic cell tumor (IDCT) is an extremely rare hematological disorder with poorly understood pathogenesis. Occasionally encountered by hematologists, unusual presentations of IDCT have never been reported in the spine literature. The authors report a case of a 51-year-old man who presented with progressively worsening axial thoracic back pain radiating to his sides for three months. MRI revealed a large 3-cm enhancing mass at the T9 vertebral body with an exophytic component causing significant canal stenosis...

BACKGROUND: An enterogenous cyst is a rare entity categorized as an intestinal cyst. In most cases, enterogenous cysts are seen in the mediastinum, peritoneal cavity, spinal canal, subarachnoid space, and cerebral ventricle. CASE PRESENTATION: A 14-year-old Asian (Japanese) boy reported feeling pain in his left groin, and a mass was found. We did not perform orchiectomy because intraoperative frozen sections showed no malignant findings. On histological examination the resected specimens contained columnar epithelium surrounded by smooth muscle...
