Imaging three-dimensional cerebellar connectivity using diffusion tractography is challenging because of the ubiquitous features of crossing axonal pathways within a folium as well as intersecting pathways from neighboring folia. We applied high-angular resolution diffusion imaging (HARDI) tractography to intact postmortem adult brainstem and cerebellum to(More)
BACKGROUND Postoperative nausea and vomiting (PONV) are common complications after anesthesia and surgery. This study was designed to compare the effects of palonosetron and ondansetron in preventing PONV in high-risk patients receiving intravenous opioid-based patient-controlled analgesia (IV-PCA) after gynecological laparoscopic surgery. METHODS One(More)
BACKGROUND Primary meningeal osteosarcomas and radiation-induced extraosseous tumors are extremely rare. We encountered a patient with a radiation-induced meningeal osteosarcoma with metastatic spread. CASE DESCRIPTION A 54-year-old man presented with a 2-week history of nausea, vomiting, and ataxia. CT and MRI studies revealed an extra-axial, dural-based(More)
provided the original work is properly cited. CC A 12-years-old boy (165 cm/72 kg) complained of severe posterior neck pain radiating to the right arm. The resting pain score was VAS 80 of 100 and on moving the neck the VAS was 90/100. X-ray and MRI showed C7-T1 intervertebral disc calci-fication (IDC) with right C8 nerve compression (Fig. 1). Conservative(More)
OBJECTIVE For the treatment of osteoporotic vertebral compression fracture, percutaneous vertebroplasty (PVP) is currently widely used as an effective and relatively safe procedure. However, some patients do not experience pain relief after PVP. We performed several additional PVP procedures in those patients who did not have any improvement of pain after(More)
Osteoporosis is a worldwide problem and it mainly affects postmenopausal women. Osteoporosis associated with pregnancy or lactation is a rare condition. The incidence and mechanism of this phenomenon has not been clarified, but it can cause one or more vertebral compression fractures with severe, prolonged back pain in the affected women. We experienced(More)
OBJECTIVE Avascular necrosis (AVN) of the vertebral body is known as a relatively uncommon phenomenon in a vertebral compression fracture (VCF). The outstanding radiologic findings of AVN are intravertebral vacuum phenomenon with or without fluid collection. Several reports revealed that PVP or balloon kyphoplasty might be the effective treatment modalities(More)
Osteoporotic patients who undergo percutaneous vertebroplasty (PVP) have the risk of a repeated collapse of their adjacent vertebral body due to alteration of load transfer into the adjacent vertebral body. The authors have experienced a rare case of repeated osteoporotic vertebral compression fractures (VCF) resulting in extreme multi-level PVP. A(More)
