Extra-axial chordoma is a chordoma that occurs in non-axial locations. It is a very rare tumor, with 20 cases reported to date; 14 in bone and six in soft tissue. Of the 14 skeletal extra-axial chordomas, ten were intramedullary and four were intracortical. We report the first case of parosteal extra-axial chordoma arising in the second metacarpal bone, expressing brachyury on immunohistochemical analysis, and describe the pathologic and radiologic findings. We suggest that extra-axial chordoma can occur in parosteal bone lesions or the hand, without features of bone distribution or bone-specific sites...

In the early days of ultrasound, it was not a translational discipline. The heart was claimed by cardiologists, with others, such as gynaecologists, urologists and vascular surgeons claiming their part while the rest was given to radiologists. Only recently, ultrasound transgressed and crossed the usual borders between the different disciplines, such as emergency and critical care medicine. The advent of portable machines in the early 1980s, allowed the critical care physician to perform bedside ultrasound, and the development of whole body critical care ultrasound (CCUS) was born...

INTRODUCTION: Pre-operative physical examination of male epispadias allows for classification of epispadias level as glanular (GE), penile (PE) or penopubic (PPE), and for delineation of anatomic anomalies. The incidence of associated extragenital abnormalities, such as vesicoureteral reflux (VUR), bladder neck (BN) abnormality and abnormal pubic diastasis (PD), and their impact on urinary continence has not yet been systematically studied. OBJECTIVE: The goal of this study was to evaluate whether the more proximal level of epispadias correlated with associated extragenital anatomic anomalies seen on initial imaging or endoscopic evaluation, and whether these pre-operative findings contributed to subsequent surgical management and impacted on achieving urinary continence...

Living kidney donor (LKD) transplantation is an important alternative for the end-stage renal disease population and is preferred due to superior outcomes when compared with dialysis or deceased donor transplantation. LKD evaluation includes a computed tomography angiogram (CTA) for assessment of renal and renovascular anatomy. Incidental nonrenal findings are frequently noted during the CTAs, and these may have variable clinical significance. These incidental findings lead to further testing, procedures, and referrals, which incur additional cost...

INTRODUCTION: Decompressive craniectomy (DC) is a lifesaving procedure but is associated to several post-operative complications, namely cerebrospinal fluid (CSF) dynamics impairment. The aim of this multicentric study was to evaluate the incidence of such CSF alterations after DC and review their impact on the overall outcome. MATERIAL AND METHODS: We performed a retrospective multicentric study to analyze the CSF disorders occurring in children aged from 0 to 17 years who had undergone a DC for traumatic brain injury (TBI) in the major Departments of Pediatric Neurosurgery of France between January 2006 and August 2016...

BACKGROUND: The treatment of sacral fractures has evolved since its first description in 1982. Several techniques for sacral augmentation have been developed since 2001, and the rate of improvement is rapid with over 50% reduction in pain achieved prior to post-procedure discharge of the patient. Pain reduction occurs primarily within the first 3 months and is sustained at 12 months; however, the long-term outcomes have not previously been studied. OBJECTIVES: We aim to evaluate the long-term efficacy of sacroplasty versus non-surgical management (NSM) in treating sacral insufficiency fractures (SIFs), including the effect on pain relief, opioid and other analgesic use, patient satisfaction, and complication rates...

BACKGROUND: Metastases to the bone are common in cancer patients, and it has been estimated that up to 50% of patients with pelvic bone metastases will not achieve adequate pain control with medications alone. This has led to a paradigm shift over recent years towards the use and development of minimally invasive image-guided treatment options for palliation of bony metastases. Despite these developments, large metastatic lesions are still often considered to be "hopeless cases" that would garner little to no benefit from image-guided intervention...

BACKGROUND: There is disagreement regarding the anatomy of the pediatric airway, particularly regarding the shape of the cricoid cartilage and the location of the narrowest portion of the larynx. AIMS: The aim of this review is to clarify the origin and the science behind these differing views. METHODS: We undertook a review of published literature, University Libraries, and authoritative textbooks with key search words and phrases. RESULTS: In vivo observations suggest that the narrowest portion of the airway is more proximal than the cricoid cartilage...

Gallstone ileus is a rare cause of bowel obstruction, which mainly affects the elderly population. The associated mortality is estimated to be up to 30%. The presentation of gallstone ileus is notoriously non-specific, and this often contributes to the delay in diagnosis. The diagnosis of gallstone ileus relies on a radiological approach, and herein we discuss the benefits and drawbacks of the use of different modalities of radiological imaging: plain abdominal films, computed tomography, magnetic resonance imaging, and ultrasound scanning...

Transarterial radioembolization is a novel therapy that has gained rapid clinical acceptance for the treatment of hepatocellular carcinoma (HCC). Segmental radioembolization [also termed radiation segmentectomy (RS)] is a technique that can deliver high doses (> 190 Gy) of radiation selectively to the hepatic segment(s) containing the tumor. The aim of this comprehensive review is to provide an illustrative summary of the most relevant imaging findings encountered after radiation segmentectomy. A 62-patient cohort of Child-Pugh A patients with solitary HCC < 5 cm in size was identified...

AIMS: Phyllodes tumour (PT) is an uncommon fibroepithelial tumour of the breast. It has a spectrum of aggressiveness in biological behaviour with chance of local recurrence and, occasionally, metastasis. METHODS: A 15-year retrospective review from a multicentre database in Hong Kong was performed. RESULTS: Clinical and pathological records of 465 patients with 469 PTs between 1998 and 2014 were reviewed. Median age of occurrence was 44 years (range 12-86 years)...

OBJECTIVE: Isolated spontaneous dissection of the superior mesenteric artery (SMA) and celiac artery (CA) remains a rare condition; however, it has been increasingly noted incidentally on diagnostic imaging. The purpose of this study was to examine the natural history and outcomes of patients presenting with isolated spontaneous mesenteric artery dissection (SMAD). We hypothesized that most SMADs can be treated nonoperatively. METHODS: This was a single-center retrospective review of patients presenting with the diagnosis of SMAD between 2006 and 2016...

Giant cell arteritis (GCA) and Takayasu arteritis (TAK) are the two main large vessel vasculitides. They share some similarities regarding their clinical, radiological and histological presentations but some pathogenic processes in GCA and TAK are activated differently, thus explaining their different sensitivity to biological therapies. The treatment of GCA and TAK essentially relies on glucocorticoids. However, thanks to major progress in our understanding of their pathogenesis, the role of biological therapies in the treatment of these two vasculitides is expanding, especially in relapsing or refractory diseases...

BACKGROUND: Intraductal tubulopapillary neoplasm (ITPN) depicts a distinct entity in the subgroup of premalignant epithelial tumors of the pancreas. Although the histomorphological and immunophenotypical characterization of ITPN has been described by several authors in terms of report of case series in the past, the rarity of that tumor subtype and similarity to other entities still makes identification of ITPN a challenge for radiologists and pathologists. To date, little is known about tubulopapillary carcinoma that can evolve from ITPN...

BACKGROUND: Repair of proximal hamstring avulsions requires mobilization of the sciatic nerve away from the tendon stump, which can be achieved with varying difficulty depending on the degree of scar formation and adherence. Predicting when a scarred, adherent, difficult-to-mobilize nerve will be encountered has been difficult.

Background: Chronic granulomatous disease (CGD) is a rare genetic disorder causing recurrent infections. Over one quarter of patients develop hepatic abscesses and liver dysfunction. Recent reports suggest disease-modifying treatment with corticosteroids is effective for these abscesses. Comparison of corticosteroid therapy to traditional invasive treatments has not been performed. Methods: Records of 268 patients with CGD treated at the National Institutes of Health (NIH) from 1980 to 2014 were reviewed...
