: Osteoporosis is a common disease with a strong genetic component. Several studies have reported the vitamin D receptor (VDR), collagen type I (COL1A1), and LDL receptor-related protein 5 (LRP5) genes as the most likely candidates. However, most of the studies have been carried out in postmenopausal women and older men and show inconsistent results. CASE PRESENTATION: We report a case of a 26-year old male who presented with severe back pain of acute onset, unrelated to any kind of trauma, and diffuse myalgia...

Positron Emission Tomography-Computed Tomography (PET-CT) is routinely used for staging and monitoring of human cancer patients and is becoming increasingly available in veterinary medicine. In this study, 18-fluorodeoxyglucose (18FDG)-PET-CT was used in dogs with naturally occurring splenic hemangiosarcoma (HSA) to assess its utility as a staging and monitoring modality as compared to standard radiography and ultrasonography. Nine dogs with stage-2 HSA underwent 18FDG-PET-CT following splenectomy and prior to commencement of chemotherapy...

An 87-year-old woman with severe aortic stenosis underwent a transfemoral transcatheter aortic valve replacement (TAVR). Intraoperative transesophageal echocardiography demonstrated a well-seated valve with no paravalvular leak; however, a new acute type B aortic dissection was identified. Endografts were delivered through the TAVR sheath and deployed, effectively treating the dissection. The patient did well postoperatively, with imaging at 2 years demonstrating a well-functioning aortic valve and no migration or endoleak of the thoracic endografts...

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...

Diffuse-type tenosynovial giant cell tumor (TS-GCT) is categorized as a locally aggressive but non-metastasizing neoplasm according to the WHO classification. Herein, we report an extremely rare case of a 41-year-old woman who developed multiple metastases from diffuse TS-GCT with benign histological features. The patient complained of a painful buttock mass and imaging studies revealed a soft tissue tumor of the buttock and multiple pulmonary nodules. The buttock tumor was excised and the final diagnosis was extra-articular diffuse-type TS-GCT...

BACKGROUND AND AIMS: Ultrasound imaging before neuraxial blocks was reported to improve the ease of insertion and minimize the traumatic trials. However, the data about the use of ultrasound in thoracic epidural block are scanty. In this study, pre-insertion ultrasound scanning was compared to traditional manual palpation technique for insertion of the thoracic epidural catheter in abdominal operations. SUBJECTS AND METHODS: Forty-eight patients scheduled to midline laparotomy under combined general anesthesia with thoracic epidural analgesia were included in the study...

BACKGROUND Kaposi sarcoma (KS) is known to involve the mucocutaneous tissues and the aero-digestive tracts. In acquired immune deficiency syndrome (AIDS) patients, KS has an aggressive course and carries poor prognosis. We present a case of pulmonary KS with osseous metastases as the first presentation of human immunodeficiency virus (HIV) infection in a young male. The lesions impressively decreased in size and numbers following initiation of highly active antiretroviral therapy (HAART). CASE REPORT A 34-year-old heterosexual male presented with a one month history of cough and 15-20 pound weight loss within six months...

For the resection of pulmonary ground glass opacity (GGO) or non-palpable nodule on video-assisted thoracic surgery (VATS), preoperative computed tomography (CT)-guided VATS marker pricking is usually performed. Recently, air embolisms after VATS marker pricking have been reported to be serious problems. The purpose of this study was to evaluate the usefulness of intraoperative cone beam CT images on VATS to avoid preoperative VATS marker pricking. The CT number of the both GGO and nodule indicate the range from -200 to -800 HU in general...

BACKGROUND: Aortic arch disease is a challenging clinical problem, especially in high-risk patients, in whom open repair can have morbidity and mortality rates of 30% to 40% and 2% to 20%, respectively. Aortic arch chimney (AAC) stents used during thoracic endovascular aortic repair (TEVAR) are a less invasive treatment strategy than open repair, but the current literature is inconclusive about the role of this technology. The focus of this analysis is on our experience with TEVAR and AAC stents...

RATIONALE AND OBJECTIVES: Imaging-based assessment of cardiovascular structure and function provides clinically relevant information in smokers. Non-cardiac-gated thoracic computed tomographic (CT) scanning is increasingly leveraged for clinical care and lung cancer screening. We sought to determine if more comprehensive measures of ventricular geometry could be obtained from CT using an atlas-based surface model of the heart. MATERIALS AND METHODS: Subcohorts of 24 subjects with cardiac magnetic resonance imaging (MRI) and 262 subjects with echocardiography were identified from COPDGene, a longitudinal observational study of smokers...

Transthoracic echocardiography ( TTE transthoracic echocardiography ) is a critical tool in the field of clinical cardiology. It often serves as one of the first-line imaging modalities in the evaluation of cardiac disease owing to its low cost, portability, widespread availability, lack of ionizing radiation, and ability to evaluate both anatomy and function of the heart. Consequently, a large majority of patients undergoing a cardiac computed tomography (CT) or magnetic resonance (MR) imaging examination will have a TTE transthoracic echocardiography available for review...

BACKGROUND: Sodium fluoride (NaF) positron emission tomography combined with computer tomography (PET/CT) has shown to be more sensitive than the whole-body bone scan in the detection of skeletal uptake due to metastases in prostate cancer. We aimed to calculate a 3D index for NaF PET/CT and investigate its correlation to the bone scan index (BSI) and overall survival (OS) in a group of patients with prostate cancer. METHODS: NaF PET/CT and bone scans were studied in 48 patients with prostate cancer...

PURPOSE: Recent pulmonary imaging research has revealed that in patients with chronic obstructive pulmonary disease (COPD) and asthma, structural and functional abnormalities are spatially heterogeneous. This novel information may help optimize treatment in individual patients, monitor interventional efficacy and develop new treatments. Moreover, by automating the measurement of regional biomarkers for the 19 different anatomical lung segments, there is an opportunity to embed imaging biomarkers into clinically-acceptable clinical workflows and improve lung disease clinical care...

A chronic expanding hematoma is a hematoma with long term, continuous growth. A 69-year-old male presented with an extra-thoracic chronic expanding hematoma 45 years after thoracoplasty. Six months prior to his visit with us, he had noticed a slight swelling on his back. Three months before his visit with us, the size of the swollen area gradually increased after bowling. Magnetic resonance imaging (MRI) showed an extra-thoracic lesion measuring 120 mm in diameter. Heterogeneous signal intensity on T1- and T2-weighted images inside the lesion was reflected as hematoma of various ages...
