Jinyoung Park, Duk Hyun Sung
Polymyalgia rheumatica (PMR) is almost an exclusive disease of adults over the age of 50, and only a few cases have been reported. Two 46-year-old females visited our locomotor pain clinic with multiple joint pain with increased acute phase reactants. Rheumatologic markers, and HLA-B27 were checked. Serum protein electrophoresis and serum immunofixation electrophoresis, imaging studies including plane image, sonography, and magnetic resonance image was done. (18)F-Fludeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) showed characteristic findings of PMR, without evidences of sacroiliitis...

An 84-year-old woman presented to our hospital with dyspnea on exertion and left back pain. Chest X-ray and chest computed tomography (CT) revealed an irregular pleural mass invading her left chest wall with rib destruction and pleural effusion. CT-guided needle biopsy revealed diffuse large B-cell lymphoma. Low-dose oral etoposide produced a complete response, and she continued oral chemotherapy for one year after the diagnosis and maintained good performance status. We herein report a very rare case of non-pyothorax-associated lymphoma that nonetheless resulted in great recovery...

Background Extraforaminal lumbar interbody fusion (ELIF) surgery is a muscle-sparing approach that allows the treatment of various degenerative spinal diseases. It is technical challenging to perform the ELIF approach at the L5-S1 level because the sacral ala obstructs the view of the intervertebral disk space. Methods We reported earlier on the ELIF technique in which the intervertebral disk is targeted at an angle of 45 degrees relative to the midline. In this article we describe the technical process we developed to overcome the anatomic relation between the sacral ala and the intervertebral disk space L5-S1 that hinders the ELIF approach at this level...

Spinal fusion via anterior lumbar interbody fusion (ALIF) can offer symptomatic relief to patients that suffer severe low back pain, radiculopathy, and claudication. However, a detailed working knowledge of the thoracic, abdominal, and lumbar anatomy, particularly of the vasculature, is vital. We report the case of a 68-year-old man who presented with radiculopathy and progressively worsening low back pain despite 9 months of unsuccessful conservative therapy and pain management. Preoperative computed tomography and magnetic resonance imaging revealed a rare anatomical variation, with an anomalous left-sided inferior vena cava and anomalous aorta...

Several studies have shown that half of all young athletes experience back pain (BP). However, high intensity and frequency of BP may be harmful, and the factors associated with BP severity have not been investigated in detail. Here, we investigated the factors associated with a high intensity and high frequency of BP in high school athletes. We included 251 athletes (173 boys and 78 girls [14-20 years old]) in this cross-sectional study. The dependent variables were a high frequency and high intensity of BP, and the independent variables were demographic, socioeconomic, psychosocial, hereditary, anthropometric, behavioural, and postural factors and the level of exercise...

We report the case of a 40-year-old female presenting with back pain that was complicated by a solitary intramedullary spinal cord mass at the T10-11 levels, confirmed by magnetic resonance imaging and computed tomography myelography. Microsurgical en bloc extirpation of the tumor approached through a recapping T-saw laminoplasty of T10 was done, and histopathology findings revealed a diagnosis of neurofibroma. Solitary spinal neurofibroma is one of the rarest tumors involving the spinal cord and is very adherent for the lack of a well-defined capsule, requiring careful dissection under microscope magnification for successful en bloc resection...
