Ankylosing Spondylitis With Bilateral Symmetrical Uptake in the Greater Trochanters on Bone Scan.

Ankylosing spondylitis is a chronic inflammatory bone disease that commonly affects the spine and the sacroiliac joints. Ankylosing spondylitis can also cause enthesitis, or enthesopathy, which is an inflammation at the tendinous or ligamentous insertion sites on the bones. In this study, we present the case of a 37-year-old man with ankylosing spondylitis with a unique Tc-HDP bone scan finding of symmetrical increased uptake bilaterally in the greater trochanters.

Pitfalls and value of organ specific approach in evaluating indeterminate lesions detected on CT in colorectal cancer by [F18] FDG PET/CT.

Objective: The objective of this study is to evaluate the value of FDG PET/CT for different involved organs showing Indeterminate/ equivocal / suspicious lesions detected on IV contrasted CT during surveillance follow up for colorectal cancer.

Materials And Methods: A total of 67 patients with colorectal cancer how are on regular surveillance follow up by IV contrasted CT scans revealing indeterminate lesions were studied. Subsequent FDG PET/CT evaluation was performed as a problem solving modality.

Successful surgical retrieval of Celt ACD® vascular closure device embolised in the tibioperoneal trunk.

Background: This report presents a case of surgical retrieval of a Celt ACD® vascular closure device (VCD) situated in the tibioperoneal trunk, following a failed attempt at deployment. Existing literature mostly recommends an endovascular approach when attempting to retrieve embolised VCDs.

Case Presentation: A 55 year old male presented with right sudden right lower limb pain and numbness 1 week following a successful left retrograde superficial femoral artery (SFA) angioplasty.

Vesico-Adnexal Fistula Treated with Transurethral Embolization Under Fluoroscopic Guidance.

BACKGROUND Vesico-adnexal fistulae are rare. Potential causes of such fistulae include infection, endometriosis, and iatrogenic causes following pelvic surgeries. To the best of our knowledge, only 3 cases of vesico-adnexal fistulae have been reported, and all these patients were treated surgically by removing the involved adnexa, excising the fistulous duct, and suturing the bladder.

Branching patterns of the aortic arch: a computed tomography angiography-based study.

Purpose: This study aimed to investigate the anatomical variations in direct branches of the aortic arch in Jordanians using the contrast Computed Tomography (CT) imaging techniques and to determine their prevalence according to sex.

Methods: This analytical, retrospective study included 500 patients (209 females, 291 males), who were referred to the Radio-Diagnostic Department at King Abdullah University Hospital for CT angiography of the aortic arch from 2010 to 2014. Patients were selected using a random sampling method.

Clinical relevance of 18F-FDG-negative osteoblastic metastatic bone lesions noted on PET/CT in breast cancer patients.

Purpose: Our study aims to assess the clinical relevance of fluorine-18 fluorodeoxyglucose (F-FDG) negative osteoblastic metastatic bone lesions noted on PET/computed tomography (CT) in breast cancer patients.

Patients And Methods: The medical records of breast cancer patients were reviewed retrospectively from January 2012 until April 2015. We included the patients who had metastatic bone disease evaluated by F-FDG-PET/CT.

Osteoblastoma is a metabolically active benign bone tumor on 18F-FDG PET imaging.

We describe a case of a 9-y-old girl who on (18)F-FDG PET imaging was found to have a highly metabolically active sacral tumor with an average standarized uptake value of 6.2. The tumor was proven to be osteoblastoma by pathologic examination.

Radiofrequency ablation of osteoid osteoma using tissue impedance as a parameter of osteonecrosis.

Introduction: The aim of this study is to assess the safety and the efficacy of radiofrequency ablation (RFA) of osteoid osteoma with Soloist monopolar electrode using tissue impedance, rather than temperature, as an indicator of osteonecrosis.

Methods: The medical records and imaging studies of 30 patients (males 18, females 12) who underwent RFA of osteoid osteoma at our institution were reviewed. The mean age of the patients was 15.

Internal jugular vein valve morphology in the patients with chronic cerebrospinal venous insufficiency (CCSVI); angiographic findings and schematic demonstrations.

Chronic cerebrospinal venous insufficiency (CCSVI) is a syndrome recently described in multiple sclerosis patients. It is characterized by abnormal venous hemodynamics resulting from numerous obstacles in the main veins draining the central nervous system, usually: the internal jugular veins and the azygous vein. Internal jugular vein is the most commonly vein affected.

Isolated lipoma of filum terminale in adults: MRI findings and clinical correlation.

Introduction: Fat within the filum terminale is frequently seen on routine magnetic resonance imaging (MRI) of the lumbosacral spine (LSS), with prevalence of 1-5%. The objective of this study was to determine the prevalence and MRI features of isolated lipoma of filum terminale (LFT) in adult population and its correlation with the patient clinical presentations.

Methods: Prospective analysis of all lumbosacral MRI performed at King Abdullah University Hospital during a 21-month period.

Reproducibility of gallbladder ejection fraction measured by Fatty meal cholescintigraphy.

Purpose: There are conflicting data in the literature regarding the reproducibility of the gallbladder ejection fraction (GBEF) measured by fatty meal cholescintigraphy (CS). We aimed to test the reproducibility of GBEF measured by fatty meal CS.

Methods: Thirty-five subjects (25 healthy volunteers and 10 patients with chronic abdominal pain) underwent fatty meal CS twice in order to measure GBEF1 and GBEF2.
