INTRODUCTION Many papers have been published recently on the subject of pseudotumors surrounding metal-on-metal hip resurfacing and replacement prostheses. These pseudotumors are sterile, inflammatory lesions within the periprosthetic tissues and have been variously termed masses, cysts, bursae, collections, or aseptic lymphocyte-dominated(More)
PURPOSE To retrospectively evaluate embolotherapy of bleeding residual uterine vascular malformations in patients with gestational trophoblastic tumors. MATERIALS AND METHODS Fourteen patients were treated over the past 20 years. Embolizations were performed with a common femoral artery approach. Duplex ultrasonography was performed before and after(More)
Metal artifact reduction sequence magnetic resonance imaging findings are reported in a prospective series of 31 patients with unexplained painful metal-on-metal (MOM) hips. The abnormalities identified were fluid collection (20 patients), solid mass (2 patients), moderate to severe muscle atrophy (23 patients), and muscle edema (8 patients). In conclusion,(More)
Gestational trophoblastic neoplasia (GTN) encompasses a broad spectrum of placental lesions from the pre-malignant hydatidiform mole (complete and partial) through to the malignant invasive mole, choriocarcinoma and rare placental site trophoblastic tumour (PSTT). Ultrasound remains the radiological investigation of choice for initial diagnosis, and it can(More)
BACKGROUND AND PURPOSE Operative findings during revision of metal-on-metal hip arthroplasty (MOMHA) vary widely and can involve massive soft tissue and bone disruption. As a result, planning of theater time and resources is difficult, surgery is challenging, and outcomes are often poor. We describe our experience with revision of MOMHA and provide(More)
Neural tube defects (NTDs) are common birth defects (~1 in 1000 pregnancies in the US and Europe) that have complex origins, including environmental and genetic factors. A low level of maternal folate is one well-established risk factor, with maternal periconceptional folic acid supplementation reducing the occurrence of NTD pregnancies by 50-70%. Gene(More)
The treatment of internal iliac artery aneurysms is aimed at the prevention of rupture. Traditionally, this is undertaken surgically; however, endovascular techniques are an acceptable alternative and these techniques are also not without complication. Herein, the authors describe the endovascular treatment of two patients with internal iliac aneurysms.(More)
Lipoma arborescens is a rare benign fat-containing synovial proliferative lesion that is typically known to affect the knee joint in adults. We present the first case of lipoma arborescens of the ankle joint in an adult patient with involvement of the intra-articluar synovium as well as the synovial sheath of the tendons around the ankle. The MRI features(More)
Minimally-invasive treatments for chronic Achilles tendinopathy may prevent the need for surgery when conservative methods have failed. Whilst injections have traditionally been used to manage symptoms, recently described therapies may also have disease-modifying potential. Ultrasound provides the ability to guide therapeutic interventions, ensuring that(More)
Injuries to muscle in the elite athlete are common and may be responsible for prolonged periods of loss of competitive activity. The implications for the athlete and his/her coach and team may be catastrophic if the injury occurs at a critical time in the athlete's diary. Imaging now plays a crucial role in diagnosis, prognostication and management of(More)
