Abstract
This short review has the aim of helping the radiologist to identify medical devices when interpreting a chest X-ray, as well as looking for their most commonly detectable complications. Nowadays, many different medical devices are used, often together, especially in critical patients. It is important for the radiologist to know what to look for and to remember the technical factors that need to be considered when checking each device's positioning.

Abstract
A systemic framework for teaching vascular sonography that is centered on hemodynamics is useful to unify the initial test-by-test approach that developed with the pioneering and expansion of the field. Vascular sonography education is most powerful when taught with a system-level view of the circulation that connects how vascular anatomy (form) and physiology (function) are inextricably linked with hemodynamics (flow). Furthermore, understanding hemodynamic principles is key to using waveform morphology as a diagnostic tool. Teaching a system-based, hemodynamic-centered aligns with the objectives of the recent Consensus Statement on Doppler Waveforms by the Society for Vascular Medicine and the Society for Vascular Ultrasound and equips the vascular sonography student to recognize, understand, and appropriately document vascular findings.

Abstract
Background Rosai-Dorfman disease (RDD) is a rare lympho-histiocytic disorder of indeterminate etiology usually presenting with lymph node involvement, and infrequently with extra-nodal manifestations. The diagnosis of this condition is challenging due to the wide spectrum of disease manifestations. Purpose To elucidate the radiologic features of this disease using multimodality imaging in histopathologically proven cases and to identify characteristic features that would enable its differentiation from its mimics. Material and Methods We retrospectively evaluated imaging studies of 19 patients with histopathologically confirmed RDD presenting to our institute between January 2004 and March 2016. Imaging modalities included magnetic resonance imaging (MRI), computed tomography, FDG-positron emission tomography (PET) CT, mammography, and ultrasonography. Results Lymphadenopathy was the most common imaging feature in our study, seen in 11 (57.8%) cases followed by sino-nasal involvement in 7 (36.8%) cases and intracranial masses in 5 (26.3%) cases. Bilateral homogeneously enhancing cervical lymphadenopathy with avidity on FDG-PET scans was the predominant abnormality on imaging. Sino-nasal involvement manifested as homogeneously enhancing soft-tissue masses occupying the paranasal sinuses. Intracranial disease manifested as sellar/suprasellar masses, dural-based lesions along the cerebral hemispheres and choroid plexus enlargement. Unusual disease manifestations included spinal, osseous, and breast lesions. Conclusion Due to the high likelihood of multifocal involvement, the recognition of RDD at one site necessitates screening of other sites for disease. Homogeneously enhancing, FDG-avid lymphadenopathy and sino-nasal masses in association with hypointense extra-nodal lesions on T2-weighted MRI are imaging features which could aid the diagnosis of RDD and facilitate its differentiation from pathologies that present in a similar manner.

Abstract
We report the case of a 58-year-old Caucasian woman who presented with a subacute cerebellar syndrome accompanied by disturbance of the hypothalamic–pituitary axis and was diagnosed with isolated neurosarcoidosis based on radiological findings including typically located cerebral lesions (infratentorial and pituitary stalk). Due to persistent clinical and radiological disease activity during several years despite escalation of immunosuppressive treatment, the diagnosis was reevaluated, and a transsphenoidal biopsy of a lesion at the pituitary stalk was performed revealing Langerhans cell histiocytosis. In this case, we discuss the different steps leading to the diagnostic error, as well as the presence of red flags, which should have led to an earlier diagnostic reevaluation.

Abstract
Multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) are chronic inflammatory diseases of the central nervous system (CNS). They may cause inflammation in the brain, spinal cord and optic nerve. Both conditions must be differentiated from CNS manifestations of other systemic autoimmune diseases such as systemic lupus erythematosus (SLE), Sjögren's syndrome, autoinflammtory diseases and sarcoidosis, since amongst others myelitis and optic nerve inflammation may also occur in these conditions. Nevertheless, coexistence of MS or NMOSD with rheumatic disorders such as SLE or Sjögren's syndrome has also been reported especially in NMOSD. Since the therapeutic approach is different it is important to determine a clear diagnosis. In addition some drugs used in rheumatic disease such as anti-tumor necrosis factor biologics may induce inflammatory disease of the CNS and should be avoided in MS. An interdisciplinary approach between neuroimmunology and rheumatology is important for optimal care and treatment in such patients.

Abstract
Spinal neurosarcoidosis is a rare form of neurosarcoid which can be challenging to diagnose given its clinical or radiographic findings are often indistinguishable from other causes of spinal demyelinating disease. We present a series of three patients with spinal neurosarcoid, all of whom demonstrated concurrent longitudinally enhancing transverse myelitis as well as spinal nerve root enhancement. These findings may be suggestive of spinal neurosarcoid and may help clinicians make the diagnosis as well as reduce the need for invasive biopsy.

Abstract
In the setting of mechanical circulatory support devices, including ventricular assist devices, extracorporeal membrane oxygenation, intraaortic balloon pumps, and the total artificial heart, the spectral Doppler waveform is significantly altered, reflecting systemic hemodynamic changes. As the prevalence of these devices increases, a better understanding of both the devices themselves and their associated Doppler ultrasound findings is necessary for accurate image interpretation. This article reviews the clinical indications, pathophysiology, and sonographic findings of these devices, with emphasis on the variation in arterial Doppler waveforms that can be seen with normal function, as well as the major complications.

Abstract
Single or multiple space-occupying lesions on brain MRI, with or without contrast enhancement and/or perilesional oedema, evoke a neoplastic origin. However, a multitude of non-neoplastic disorders can simulate cerebral neoplasia. In this review, we will discuss the MRI characteristics of non-neoplastic disorders that can mimic cerebral neoplasia. Distinguishing MRI characteristics are discussed for each of these non-neoplastic disorders.

Abstract
The diagnosis and treatment of neurosarcoidosis can be very challenging for several reasons. It affects clinically 5%-10% of sarcoidosis patients, but can be found in up to 25% of autopsies. These data reveal that a high percentage of asymptomatic or misdiagnosed cases can be missed at an initial diagnostic approach. Clinical and imaging findings are often non-specific since they can be found in a large number of neurological disorders. Histopathology can also be confounding if not performed by an expert pathologist and not placed in an appropriate clinical context. In this review, we discuss clinical features, laboratory findings, imaging, and histology of neurosarcoidosis, and we report current evidence regarding drug therapy. We conclude that a correct diagnostic approach should include a multidisciplinary evaluation involving clinicians, radiologists, and pathologists and that future studies should evaluate the genetic signature of neurosarcoidosis as they could be helpful in the assessment of this uncommon disease. With head-to-head comparisons of medical treatment for neurosarcoidosis still lacking due to the rarity of the disease and an increasing number of immunomodulating therapies at hand, novel therapeutic approaches are to be expected within the next few years.

Abstract
Chronic meningitis is defined as an inflammatory cerebrospinal fluid (CSF) profile that persists for at least 1 month. The presentation often includes headache, nausea, vomiting, cranial neuropathies, symptoms of elevated intracranial pressure, or focal neurologic deficits. The most common etiologies of chronic meningitis fall into 3 broad categories: infectious, autoimmune, and neoplastic. Evaluation of the patient with suspected chronic meningitis should include a detailed history and physical examination as well as repeated CSF diagnostics, serologic studies, and biopsy of the brain or other abnormal tissue (eg, lymph node or lung), when indicated. Early identification of the etiology and rapid treatment are crucial for improving morbidity and mortality, but potential infectious and neoplastic conditions should be excluded prior to empirically starting steroids or immunosuppressive medications.

Abstract
PURPOSE OF REVIEW The aims of this article are to discuss the epidemiology, pathophysiology and clinical phenomenology of neurosarcoidosis, as well as current approaches to diagnosis and treatment. This review focuses on central nervous system (CNS) complications of sarcoidosis. RECENT FINDINGS Neurosarcoidosis is a rare disorder with diverse clinical manifestations and outcomes. It is often difficult to diagnose and even more difficult to treat. New diagnostic approaches include the use of [¹⁸F]-fluorodeoxyglucose PET to identify potential biopsy sites. Success has been reported in the treatment of steroid refractory cases with disease-modifying therapies that were originally designed to manage other chronic inflammatory conditions by neutralizing key cytokines or depleting leukocyte subsets. SUMMARY The diagnosis and management of neurosarcoidosis can be challenging. Currently, the disorder is treated with corticosteroids in combination with global immunosuppressant agents and/or immunomodulatory monoclonal antibodies, such as infliximab. The development of novel CNS penetrant drugs that are particularly effective at inhibiting granuloma formation would represent a significant therapeutic advance. Future progress will be informed by a deeper understanding of the pathways underlying the granulomatous inflammation characteristic of sarcoidosis and by an increased appreciation of how sarcoid lesions evolve in the CNS microenvironment.

Abstract
PURPOSE OF REVIEW This article describes the background, clinical presentation, diagnosis, and treatment of selected etiologies of subacute and chronic meningitis. Key diagnostic considerations when evaluating a patient presenting with chronic inflammation of the CNS are discussed, and several specific infectious, neoplastic, and autoimmune etiologies are reviewed in detail. RECENT FINDINGS With recent advancement in serologic and CSF diagnostic testing, specific infectious, neoplastic, or autoimmune etiologies of chronic meningitis can be identified. Eliminating previous diagnostic uncertainty of chronic inflammation in the CNS has led to rapid and specific treatment regimens that ultimately improve patient outcomes. Recent advances in imaging have also aided clinicians in both their diagnostic approach and the detection of inflammatory complications such as hydrocephalus, hemorrhage, and ischemic stroke. SUMMARY Meningitis is defined as inflammation involving the meninges of the brain and spinal cord. Meningitis can be categorized as acute, subacute, or chronic based on duration of inflammation. This article focuses on the most common causes of subacute and chronic meningitis. Chronic meningitis is commonly defined as inflammation evolving during weeks to months without resolution of CSF abnormalities. Determining the time course of meningitis is important for creating a differential diagnosis. Most organisms causing acute meningitis rarely persist more than a few weeks. Although numerous etiologies of subacute and chronic meningitis have been identified, this article focuses on the most common etiologies: (1) infectious, (2) autoimmune, and (3) neoplastic.

Abstract
We report a 61-year-old woman with definite diagnosis of isolated neurosarcoidosis in the medulla oblongata involving the fourth ventricle. We could not recognize neurosarcoidosis as one of the differential diagnoses of the lesion before biopsy because the brainstem lesion location and periventricular lesion configuration were quite unusual.
