Background Large bone defects and losses play a crucial role in both tumour surgery and in complex primary and revision total knee replacement. The established options of cemented or uncemented long intramedullary stems are limited by large bone defects and are at risk from relatively high exposure to aseptic loosening. There is no general valid agreement on implant fixation of the distal femur. A further option is the cementless fixation method with compressive osseointegration, based on the so-called Wolff law of bone remodelling...

The Liver Imaging Reporting and Data System (LI-RADS) standardizes the interpretation, reporting, and data collection for imaging examinations in patients at risk for hepatocellular carcinoma (HCC). It assigns category codes reflecting relative probability of HCC to imaging-detected liver observations based on major and ancillary imaging features. LI-RADS also includes imaging features suggesting malignancy other than HCC. Supported and endorsed by the American College of Radiology (ACR), the system has been developed by a committee of radiologists, hepatologists, pathologists, surgeons, lexicon experts, and ACR staff, with input from the American Association for the Study of Liver Diseases and the Organ Procurement Transplantation Network/United Network for Organ Sharing...

OBJECTIVE: The purposes of this article are to detail the experience of a single-center academic institution in applying the patient-centered approach to a lung cancer screening program and to examine how this approach can expand to other aspects of follow-up imaging of lung nodules. CONCLUSION: As the practice of patient-centered radiology gains attention, diagnostic radiologists are findings new ways to become more involved in patient care. A lung cancer screening program is one opportunity for radiologists to consult with and educate patients...

In this report, we present two cases of patients with cerebrospinal fluid (CSF) otorrhea who underwent surgical repair through either a transmastoid or middle cranial fossa approach. In our first case, a 34-year-old male after head trauma with conductive hearing loss and a House-Brackmann grade 2 facial palsy was found to have a soft tissue mass protruding through his right tympanic membrane. Radiological examination revealed a wide tegmen tympani defect. He underwent surgery via a transmastoid approach with repair of the defect and blind sac closure of the external auditory canal after middle ear cavity obliteration...

Supratentorial embryonal tumours are very rare malignant tumours of neuroectodermal origin, characterized by an aggressive clinical behavior. They occur prevalently in children. They have been sporadically described in adults and represent an even rarer occurrence in elderly patients, raising many issues on the diagnostic pitfalls and their appropriate management. We present an unusual case of embryonal tumor in a 62-year-old man who presented with speech disorder, left IIIrd and Vth cranial nerves partial deficit secondary to a left temporo-insular embryonal tumour: clinico-radiological features, histopathological insights, therapeutic options and results are discussed along with a review of the most relevant literature, addressing the specific issue of differential diagnosis and the expected results in the elderly population...

Endolymphatic sac tumour (ELST) is infrequent, as emerges from small series reported in the literature. It is a slow-growing malignancy with local aggressiveness and a low risk of distant metastases. It is often misdiagnosed because of the late onset of symptoms and difficulty in obtaining a biopsy. Its frequency is higher in von Hippel-Lindau (VHL) disease (a genetic systemic syndrome involving multiple tumours), with a prevalence of around 25%. The diagnosis is based on radiology, with specific patterns on contrast-enhanced MRI and typical petrous bone erosion on bone CT scan...

BACKGROUND: Interstitial lung disease (ILD) complicates the course of systemic sclerosis (SSc), representing the main cause of death in these patients. The identification of parameters that can predict the early onset and progression of ILD in SSc represents an unmet need in clinical practice. The study was designed to explore whether the surfactant proteins (SP) A and D may be used as noninvasive tools for the early identification of ILD in SSc. Alveolar exhaled nitric oxide (NO) was investigated as a surrogate marker of distal inflammation...

INTRODUCTION: Postoperative collections are an important cause of morbidity following obesity surgery. Surgical revision is most often required if general sepsis is present. Conservative treatment consists of broad spectrum antibiotics and percutaneous drainage of any collection. EUS drainage is a new technique that is gaining momentum allowing an easy access to collections close to the GI tract. MATERIALS AND METHODS: We present the case report of a 39-year-old woman who underwent to robotic Roux-en-Y gastric bypass for morbid obesity...

Leptomeningeal carcinomatosis (LC) is found in around 4% of patients with non-small cell lung cancer (NSCLC). The most common radiological finding of LC is diffuse leptomeningeal enhancement on contrast-enhanced brain magnetic resonance imaging (MRI). Herein, we report a novel brain MRI finding-non-enhanced, band-like, symmetric restricted diffusion along the anterior surface of the brainstem-of LC in four patients with NSCLC. We also identified three additional cases with similar MRI findings in a literature review...

BACKGROUND & AIMS: Stroke involving the brainstem (SBS) causes severe oropharyngeal dysphagia (OD). Research on the therapeutic efficacy of vagus nerve modulation (VNM) by using repetitive transcranial magnetic stimulation (rTMS) in SBS patients with OD has been limited thus far. We aimed to assess the effect of VNM by using rTMS in improving swallowing function after SBS. METHOD: We conducted a sham-controlled, double-blinded, parallel pilot study in 28 SBS patients with OD randomly allocated to a real rTMS group (n = 13; TMSreal) or a sham group (n = 15; TMSsham)...
