Abstract
Cancer therapy duration is variable and may take years, adding a new challenge of maintaining the best life quality for cancer survivors. In cancer patients, late-onset toxicities have been reported with monoclonal antibodies and may involve several body organs or systems. They are defined as an autoimmune illnesses that can happen months to years after treatment discontinuation. Late-onset toxicities have become a focus of clinical care and related research. After cancer therapy is completed, the patient should receive longitudinal follow-up to detect these late effects as early as possible. The current review summarizes the recently reported late-onset toxicities of four classes of monoclonal antibodies (anti-CD52, anti-CTLA-4, anti-PD-1 and anti-CD20) with guidance for the diagnostic tools, appropriate management and treatment.

Abstract
Neurosarcoidosis (NS) is an often severe, destructive manifestation with a likely under-reported prevalence of 5 to 15% of sarcoidosis cases, and in its active phase demands timely treatment intervention. Clinical signs and symptoms of NS are variable and wide-ranging, depending on anatomical involvement. Cranial nerve dysfunction, cerebrospinal parenchymal disease, aseptic meningitis, and leptomeningeal disease are the most commonly recognized manifestations. However, non-organ-specific potentially neurologically driven symptoms, such as fatigue, cognitive dysfunction, and small fiber neuropathy, appear frequently.Heterogeneous clinical presentations and absence of any single conclusive test or biomarker render NS, and sarcoidosis itself, a challenging definitive diagnosis. Clinical suspicion of NS warrants a thorough systemic and neurologic evaluation hopefully resulting in supportive extraneural physical exam and/or tissue findings. Treatment targets the severity of the manifestation, with careful discernment of whether NS reflects active potentially reversible inflammatory granulomatous disease versus inactive postinflammatory damage whereby functional impairment is unlikely to be pharmacologically responsive. Non-organ-specific symptoms are poorly understood, challenging in deciphering reversibility and often identified too late to respond to conventional immunosuppressive/pharmacological treatment. Physical therapy, coping strategies, and stress reduction may benefit patients with all disease activity levels of NS.This publication provides an approach to screening, diagnosis, disease activity discernment, and pharmacological as well as nonpharmacological treatment interventions to reduce disability and protect health-related quality of life in NS.

Abstract
As sarcoidosis may involve any organ, sarcoidosis patients should be evaluated for occult disease. Screening for some organ involvement may not be warranted if it is unlikely to cause symptoms, organ dysfunction, or affect clinical outcome. Even organ involvement that affects clinical outcome does not necessarily require screening if early detection fails to change the patient's quality of life or prognosis. On the other hand, early detection of some forms of sarcoidosis may improve outcomes and survival. This manuscript describes the approach to screening sarcoidosis patients for previously undetected disease. Screening for sarcoidosis should commence with a meticulous medical history and physical examination. Many sarcoidosis patients present with physical signs or symptoms of sarcoidosis that have not been recognized as manifestations of the disease. Detection of sarcoidosis in these instances depends on the clinician's familiarity with the varied clinical presentations of sarcoidosis. In addition, sarcoidosis patients may present with symptoms or signs that are not related to specific organ involvement that have been described as parasarcoidosis syndromes. It is conjectured that parasarcoidosis syndromes result from systemic release of inflammatory mediators from the sarcoidosis granuloma. Certain forms of sarcoidosis may cause permanent and serious problems that can be prevented if they are detected early in the course of their disease. These include (1) ocular involvement that may lead to permanent vision impairment; (2) vitamin D dysregulation that may lead to hypercalcemia, nephrolithiasis, and permanent kidney injury; and (3) cardiac sarcoidosis that may lead to a cardiomyopathy, ventricular arrhythmias, heart block, and sudden death. Screening for these forms of organ involvement requires detailed screening approaches.

Clinical Presentations, Pathogenesis, and Therapy of Sarcoidosis: State of the Art. J Clin Med 2020; 9:jcm9082363.

Abstract
Sarcoidosis is a systemic disease of unknown etiology characterized by the presence of noncaseating granulomas that can occur in any organ, most commonly the lungs. Early and accurate diagnosis of sarcoidosis remains challenging because initial presentations may vary, many patients are asymptomatic, and there is no single reliable diagnostic test. Prognosis is variable and depends on epidemiologic factors, mode of onset, initial clinical course, and specific organ involvement. From a pathobiological standpoint, sarcoidosis represents an immune paradox, where an excessive spread of both the innate and the adaptive immune arms of the immune system is accompanied by a state of partial immune anergy. For all these reasons, the optimal treatment for sarcoidosis remains unclear, with corticosteroid therapy being the current gold standard for those patients with significantly symptomatic or progressive pulmonary disease or serious extrapulmonary disease. This review is a state of the art of clinical presentations and immunological features of sarcoidosis, and the current therapeutic approaches used to treat the disease.

Abstract
PURPOSE OF REVIEW This article provides an overview and update on the neurologic manifestations of sarcoidosis. RECENT FINDINGS The 2018 Neurosarcoidosis Consortium diagnostic criteria emphasize that biopsy is key for diagnosis and determines the level of diagnostic certainty. Thus, definite neurosarcoidosis requires nervous system biopsy and probable neurosarcoidosis requires biopsy from extraneural tissue. Without biopsy, possible neurosarcoidosis can be diagnosed if the clinical, imaging, and laboratory picture is compatible and other causes are ruled out. Recent large retrospective studies from the United States and France established that infliximab appears to be efficacious when other treatments are inadequate. SUMMARY Sarcoidosis is a multisystem noninfectious granulomatous disorder that is immune mediated, reflecting the response to an as-yet unidentified antigen or antigens. Neurosarcoidosis refers to neurologic involvement due to sarcoidosis that clinically manifests in 5% of cases of sarcoidosis, with asymptomatic involvement in as many as another one in five patients with sarcoidosis. Sarcoid granulomas can occur in any anatomic substrate in the nervous system, causing protean manifestations that have earned neurosarcoidosis the sobriquet the great mimic. Nevertheless, central nervous system sarcoidosis occurs in well-defined presentations that can be classified as cranial neuropathies, meningeal disease, brain parenchymal (including pituitary-hypothalamic) disease, and spinal cord disease. In addition, the peripheral nervous system is affected in the form of peripheral neuropathy and myopathy. Glucocorticoids are the cornerstone of treatment, especially in the acute stage, whereas steroid-sparing agents such as methotrexate, mycophenolate mofetil, and azathioprine are used for prolonged therapy to minimize steroid toxicity. Anti-tumor necrosis factor agents may help in refractory cases.

Abstract
BACKGROUND Immune checkpoint inhibitors have transformed the treatment landscape for many cancers, including metastatic melanoma, but have also opened the door for a diverse variety of immune-related adverse effects. CASE PRESENTATION We describe the first reported case of presumed neurosarcoidosis as an immune-related adverse effect that developed nearly a year after discontinuation of treatment with combination ipilimumab and nivolumab for recurrent metastatic melanoma. The patient was noted to develop clinical signs consistent with systemic sarcoidosis shortly after the initiation of treatment and underwent a biopsy of hilar lymphadenopathy that confirmed sarcoidosis and after which immunotherapy was discontinued. His melanoma remained stable on surveillance imaging for the next year after which time he developed neurological symptoms and was found to have MRI brain abnormalities without evidence of intracranial metastatic disease, consistent with probable neurosarcoidosis given biopsy-proven systemic sarcoidosis and lack of evidence of CNS infection or malignancy. He underwent treatment with high dose steroids, followed by infliximab, and then methotrexate with both clinical and radiographic improvement within 4 months of starting treatment. CONCLUSIONS Immune-related adverse effects often occur within 3-6 months of receiving immune checkpoint inhibitor therapy, with some reports of late toxicity. This report highlights a case of probable neurosarcoidosis nearly a year after discontinuation of immune checkpoint therapy. The potential for durable responses after discontinuation of therapy also likely underscores a potential for late toxicity. In patients presenting with new or unexplained symptoms after checkpoint inhibitor therapy, the index of suspicion for an immune-related adverse effect should remain high, irrespective of timing.

Abstract
PURPOSE OF REVIEW Sarcoidosis is a multisystemic inflammatory disease that commonly affects the eye and less often the neuro-ophthalmic pathways. The manifestations can be quite variable but can have characteristic signs and clinical features. This review provides a comprehensive overview of the various ocular and neuro-ophthalmic manifestations of sarcoidosis, emerging diagnostic measures and approach to treatment. Particular focus is given to recent advances in diagnostic approach and available treatment options. RECENT FINDINGS Laboratory investigations, chest and nuclear medicine imaging remain important techniques for helping to diagnose sarcoidosis. Recent evidence suggests a role for aqueous humor analysis in the diagnosis of ocular sarcoidosis. Characteristic neuroimaging may help differentiate neurosarcoidosis from other causes. The role of blind conjunctival biopsy for suspected neurosarcoidosis is discussed. The emerging role and use of biologics is delineated for the treatment of both ocular and neuro-ophthalmic sarcoidosis. SUMMARY Sarcoidosis can affect any part of the visual system: the most common ocular manifestation is uveitis and the most common neuro-ophthalmic manifestation is optic neuropathy. Although diagnosis remains challenging, recent advancements in diagnosis are promising. Emerging biologics with particular efficacy for ocular and neuro-ophthalmic disease provide expanding treatment options for sight-threatening disease.

Abstract
Sarcoidosis has innumerable clinical manifestations, as the disease may affect every body organ. Furthermore, the severity of sarcoidosis involvement may range from an asymptomatic state to a life-threatening condition. This manuscript reviews a wide variety of common and less common clinical characteristics of sarcoidosis. These manifestations are presented organ by organ, although additional sections describe systemic and multiorgan presentations of sarcoidosis. The lung is the organ most commonly involved with sarcoidosis with at least 90 % of sarcoidosis patients demonstrating lung involvement in most series. The skin, eye, liver, and peripheral lymph node are the next most commonly clinically involved organs in most series, with the frequency of involvement ranging from 10 to 30 %. The actual frequency of sarcoidosis organ involvement is probably much higher as it is frequently asymptomatic and may avoid detection. This is particularly common with lung, liver, cardiac, and bone involvement. Cardiac sarcoidosis is present in 25 % of all sarcoidosis but only causes clinical problems in 5 % of them. Nevertheless, unlike sarcoidosis involvement of most other organs, it may be suddenly fatal. Therefore, it is important to screen for cardiac sarcoidosis in all sarcoidosis patients. All sarcoidosis patients should also be screened for eye involvement as asymptomatic patients may have eye involvement that may cause permanent vision impairment. Pulmonary fibrosis from sarcoidosis is usually slowly progressive but may be life-threatening because of the development of respiratory failure, pulmonary hypertension, or hemoptysis related to a mycetoma or bronchiectasis. Some manifestations of sarcoidosis are not organ-specific and probably are the result of a release of mediators from the sarcoid granuloma. Two such manifestations include small fiber neuropathy and fatigue syndromes, and they are observed in a large percentage of patients.

Abstract
Sarcoidosis of the spinal cord is a rare disease. The aims of this study are to describe the features of spinal cord sarcoidosis (SCS) and identify prognostic markers. We analyzed 20 patients over a 20-year period in 8 French hospitals. There were 12 men (60 %), mostly Caucasian (75 %). The median ages at diagnosis of sarcoidosis and myelitis were 34.5 and 37 years, respectively. SCS revealed sarcoidosis in 12 patients (60 %). Eleven patients presented with motor deficit (55 %) and 9 had sphincter dysfunction (45 %). The median initial Edmus Grading Scale (EGS) score was 2.5. The cerebrospinal fluid (CSF) showed elevated protein level (median: 1.00 g/L, interquartile range (IQR) 0.72-1.97), low glucose level (median 2.84 mmol/L, IQR 1.42-3.45), and elevated white cell count (median 22/mm(3), IQR 6-45). The cervical and thoracic cords were most often affected (90 %). All patients received steroids and an immunosuppressive drug was added in 10 cases (50 %). After a mean follow-up of 52.1 months (range 8-43), 18 patients had partial response (90 %), 7 displayed functional impairment (35 %), and the median final EGS score was 1. Six patients experienced relapse (30 %). There was an association between the initial and the final EGS scores (p = 0.006). High CSF protein level showed a trend toward an association with relapse (p = 0.076). The spinal cord lesion was often the presenting feature of sarcoidosis. Most patients experienced clinical improvement with corticosteroids and/or immunosuppressive treatment. The long-term functional prognosis was correlated with the initial severity.

Abstract
OBJECTIVE Neurosarcoidosis is a rare granulomatous disease that can result in cranial neuropathy, chronic meningitis, and intracranial granuloma formation. Meningeal involvement may cause focal nodular enhancement that can simulate common cranial base tumors. The objective of the current study is to further define the clinical features of neurosarcoidosis in a large cohort of patients, focusing on characteristics relevant to the skull base surgeon. STUDY DESIGN Retrospective series. SETTING Two tertiary academic referral centers. PATIENTS Consecutive patients diagnosed with neurosarcoidosis. INTERVENTION(S) Review of clinical presentation, physical examination, radiologic findings, biopsy results, and laboratory testing. MAIN OUTCOME MEASURES Prevalence and distribution of cranial neuropathy, radiologic features of meningeal enhancement, and patterns of simulated tumors. RESULTS A total of 305 patients met study criteria. The mean age at diagnosis was 47 years and 53% were female. The optic nerve was the most commonly involved cranial nerve, followed by the trigeminal and the facial nerve. Meningeal enhancement was present in 67% of cases with 17% demonstrating focal or multicentric nodular enhancement simulating tumor. The most common locations of inflammatory tumor development included the cavernous sinus, petrous temporal bone, and sphenoid wing; six patients had bilateral internal auditory canal lesions, several mimicking neurofibromatosis type II. CONCLUSION Establishing the diagnosis of neurosarcoidosis remains challenging. Meningeal involvement and cranial neuropathy often mimic other more common conditions. Careful review of patient history and clinical imaging can reveal important clues toward the diagnosis of neurosarcoidosis. The clinician must maintain a high index of suspicion in patients with atypical presentation to avoid misdiagnosis and facilitate early medical treatment.

Abstract
We discuss a case of a 61-year-old woman who presented with substernal chest pain. She was found to have elevated calcium levels, anemia, and acute kidney injury. The hypercalcemia persisted despite therapy with fluids and bisphosphonates. She was found to have nonparathyroid hormone (PTH) mediated hypercalcemia. The chest X-ray did not reveal any pathology. Our Initial impression was likely underlying hematologic malignancy such as lymphoma or multiple myeloma. A bone marrow biopsy was performed that revealed nonnecrotizing granulomatous inflammation. Further workup revealed elevated vitamin 1,25 dihydroxy level, beta-two microglobulin level, and ACE levels. Noncontrast computed tomography (CT) scan of chest showed bilateral apical bronchiectasis, but did not show any lymphadenopathy or evidence of malignancy. Subsequently, a fiber optic bronchoscopy with transbronchial biopsy showed nonnecrotizing granulomatous inflammation consistent with sarcoidosis. After initiating glucocorticoid therapy, the patient's hypercalcemia improved and her kidney function returned to baseline.

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
A 59-year-old woman was admitted to our hospital for an evaluation of a 10-day history of progressive pain and hypoesthesia of the right lower back associated with fever and constipation. Sarcoidosis was confirmed on mediastinal lymph node and skin biopsies. Although the neurological symptoms were suspected due to sarcoidosis-induced nerve dysfunction, nerve conduction studies and other routine examinations did not show any abnormalities. The intraepidermal nerve fiber density assessed on a skin biopsy was significantly reduced, suggesting small-fiber neuropathy (SFN). The patient was finally diagnosed with sarcoidosis-induced SFN, and her neurological symptoms were effectively relieved with high-dose steroid therapy.

Abstract
Sarcoidosis is a systemic granulomatous disease characterized by the presence of non-caseating granulomas. Its etiology remains obscure. A plausible hypothesis suggests that a complex interplay of host factors, infectious processes, and non-infectious environmental factors, matched with a susceptible genetic background, results in a pathway that leads to systemic granulomatous inflammation. Although presentations of sarcoidosis vary enormously, multi-organ involvement is a common feature. Cutaneous involvement occurs in about 25% of patients with protean manifestations and variable prognoses. Skin manifestations are divided into specific lesions with histopathologically evident non-caseating granulomas and nonspecific lesions arising from a reactive process that does not form granulomas. A peculiar form of cutaneous sarcoidosis is represented by sarcoidal lesions at sites of trauma that has caused scarring. The pathogenesis of scar sarcoidosis remains unknown. Scar sarcoidosis is also associated with herpes zoster infection, surgery, and tattooing. Such heterogeneous events, along with those at the sites of chronic lymphedema, thermal burns, radiation dermatitis, and vaccinations, occur on areas of vulnerable skin labeled "immunocompromised districts". Numerous options are available for the treatment of cutaneous sarcoidosis. Although corticosteroids remain the treatment of choice for initial systemic therapy, other nonsteroidal agents have proven effective and therefore useful for long-term management. Tumor necrosis factor-α antagonists such as infliximab may have a role in the treatment of cutaneous sarcoidosis, especially in refractory cases that are resistant to standard regimens. Elucidation of the relationship of sarcoidal granulomas with malignancy and immunity may facilitate a better understanding of some pathomechanisms operating in neoplastic and immunity-related disorders.

Abstract
Sarcoidosis (SA) is a granulomatous, multisystem disease of unknown etiology. Most often the disease affects lungs and mediastinal lymph nodes, but it may occur in other organs. Neurosarcoidosis (NS) more commonly occurs with other sarcoidosis forms, in 1 % of cases it involves only nervous system. Symptomatic NS occurs but on autopsy study up to 25 % of cases are confirmed. NS can affect central nervous system: the brain, spinal cord and peripheral nerves, and muscles. The diagnosis of neurosarcoidosis facilitates diagnostic criteria: histopathological, imaging and cerebrospinal fluid examination, and clinical symptoms. At present, there are no set standards for treatment of patients suffering from NS. Early therapy of symptomatic patients is recommended. Corticosteroids still are the first line of treatment for NS patients. In cases of steroids resistance, lack of their effectiveness or existence of contraindication to their use, immunosuppressant treatment is recommended. The latest NS algorithm with immunosuppressive treatment is discussed.

Abstract
Sarcoidosis can be a major therapeutic challenge given its multiplicity of clinical presentations, variable combination of organ involvement and severity, and unpredictable longitudinal behaviour. Six manifestations of sarcoidosis are especially difficult to manage because of (i) an incomplete knowledge of causation - fatigue and small fibre neuropathy, (ii) the rare occurrence in sarcoidosis - intra-abdominal complications or (iii) the potentially life-threatening consequences in some patients - neurological disease, pulmonary hypertension and hypercalcaemia. In none of these situations have a prospective, double-blind, placebo-controlled trial of any therapy been conducted. Despite this absence of any firm evidence base to support therapeutic recommendations, these six entities can be extremely problematic for the practising clinician. It is for this reason that we have focused in this review on these six disease manifestations and provided a synopsis of each problem together with suggested treatment approaches, based on an analysis of the current literature.

Abstract
Transverse myelitis is an acute inflammatory disease of the spinal cord, characterized by rapid onset of bilateral neurological symptoms. Weakness, sensory disturbance, and autonomic dysfunction evolve over hours or days, most progressing to maximal clinical severity within 10 days of onset. At maximal clinical severity, half will have a paraparesis, and almost all patients have sensory disturbance and bladder dysfunction. Residual disability is divided equally between severe, moderate and minimal or none. The causes of transverse myelitis are diverse; etiologies implicated include demyelinating conditions, collagen vascular disease, and parainfectious causes, however, despite extensive diagnostic work-up many cases are considered idiopathic. Due to heterogeneity in pathogenesis, and the similarity of its clinical presentation with those of various noninflammatory myelopathies, transverse myelitis has frequently been viewed as a diagnostic dilemma. However, as targeted therapies to optimize patient outcome develop, timely identification of the underlying etiology is becoming increasingly important. In this review, we describe the imaging and clinical features of idiopathic and disease-associated transverse myelitis and its major differentials, with discussion of how MR imaging features assist in the identification of various sub-types of transverse myelitis. We will also discuss the potential for advanced MR techniques to contribute to diagnosis and prognostication.

Abstract
Neurosarcoidosis (NS) more commonly occurs in the setting of systemic disease. The diagnosis is based on a clinical history suggestive of NS, presence of noncaseating granulomas, and supportive evidence of sarcoid pathology, laboratory, and imaging studies. NS could involve any part of the nervous system and often demands high doses of steroids for symptom control. It presents low response to isolated steroids administration and frequently requires immunosuppressive agents. In NS, lymphocytes are polarized toward an excessive Th1 response, leading to overproduction of TNF-alpha and INF-gama, as well as lL-2 and IL-15. Infliximab, a chimeric monoclonal antibody that neutralizes the biological activity of TNF-alpha, is a new option in the NS treatment. We revised pathophysiology, clinical manifestations, diagnostic work up, and treatment of NS as guidance for the general neurologist.

Abstract
ARA 290 (a peptide designed to activate the innate repair receptor that arrests injury and initiates cytoprotection, antiinflammation and healing) reduces allodynia in preclinical neuropathy models. We studied the safety and efficacy of ARA 290 to reduce symptoms of small fiber neuropathy (SFN) in patients with sarcoidosis. A total of 22 patients diagnosed with sarcoidosis and symptoms of SFN were enrolled in a double-blind, placebo-controlled exploratory trial consisting of three times weekly intravenous dosing of ARA 290 (2 mg; n = 12) or placebo (n = 10) for 4 wks. Inclusion criteria were a diagnosis of neuropathy and a spontaneous pain score of ≥5 (Brief Pain Inventory [BPI]). Endpoints assessed were changes in pain intensity and the small fiber neuropathy screening list (SFNSL) score, quality of life (SF-36), depressive symptoms (Inventory of Depressive Symptomatology [IDS]) and fatigue (Fatigue Assessment Scale [FAS]). No safety concerns were raised by clinical or laboratory assessments. The ARA 290 group showed significant (p < 0.05) improvement at wk 4 in SFNSL score compared with placebo (Δ -11.5 ± 3.04 versus Δ -2.9 ± 3.34 [standard error of the mean]). Additionally, the ARA 290 group showed a significant change from baseline in the pain and physical functioning dimensions of the SF-36 (Δ -23.4 ± 5.5 and Δ -14.6 ± 3.9, respectively). The mean BPI and FAS scores improved significantly but equivalently in both patient groups. No change was observed in the IDS. ARA 290 appears to be safe in patients with sarcoidosis and can reduce neuropathic symptoms.

Abstract
AIM To assess clinical features, treatment and outcome of Hypothalamo-pituitary (HP) sarcoidosis and to determine whether HP is associated with a particular clinical phenotype of sarcoidosis. DESIGN Multicentric retrospective study. METHODS Retrospective chart review. Each patient was matched with two controls. RESULTS Twenty-four patients were identified (10 women, 14 men). Their median age at the sarcoidosis diagnosis was 31.5 years (range: 8-69 years). HP involvement occurred in the course of a previously known sarcoidosis in 11 cases (46%), whereas it preceded the diagnosis in 13 patients (54%). All but two patients had anterior pituitary dysfunction, 12 patients presented with diabetes insipidus. The most common hormonal features were gonadotropin deficiency (n=21), TSH deficiency (n=15) and hyperprolactinemia (n=12). Magnetic Resonance Imaging (MRI) revealed infundibulum involvement (n=8), pituitary stalk thickness (n=12) and involvement of the pituitary gland (n=14). All but two patients received prednisone. After a mean follow-up of 4 years, only two patients recovered from hormonal deficiencies. MRI abnormalities improved or disappeared in 12 cases under corticosteroid. There was no correlation between the hormonal dysfunctions and the radiologic outcomes. Patients with HP sarcoidosis had significantly more frequent sinonasal localizations and neurosarcoidosis and required a systemic treatment more frequently than controls. CONCLUSION Although HP sarcoidosis is unusual, physicians should be aware that such specific localization could be the first manifestation of sarcoidosis. HP involvement is associated with general severity of sarcoidosis. MRI abnormalities can improve or disappear under corticosteroid treatment, but most endocrine defects are irreversible.

Abstract
Neuro-ophthalmic disease occurs in about a third of patients with neurosarcoidosis. Optic nerve involvement is the most common manifestation, but other cranial nerves and the optic chiasm can be involved. However, there are several other common diseases that cause optic neuropathy, including multiple sclerosis. The diagnosis of sarcoidosis can often be made based on the multi-organ nature of the disease and ancillary testing. Most patients with neuro-ophthalmic sarcoidosis require systemic therapy. While corticosteroids are usually the first step in therapy, cytotoxic agents such as methotrexate and azathioprine have been useful as steroid-sparing agents for chronic disease. The monoclonal antibodies directed against tumor necrosis factor have been reported as effective in refractory cases of neuro-ophthalmic disease.

Abstract
Transverse myelitis is an acute inflammatory condition. A relatively rare condition, the diversity of causes makes it an important diagnostic challenge. An approach to the classification and work-up standardizes diagnostic criteria and terminology to facilitate clinical research, and forms a useful tool in the clinical work-up for patients at presentation. Its pathogenesis can be grouped into four categories. Imaging appearances can be nonspecific; however, the morphology of cord involvement, enhancement pattern, and presence of coexistent abnormalities on MR imaging can provide clues as to the causes. Neuroimaging is important in identifying subgroups that may benefit from specific treatment.

Abstract
BACKGROUND Small fiber neuropathy (SFN) is commonly associated with sarcoidosis and can cause significant morbidity to afflicted patients. The appropriate treatment of this condition, when associated with sarcoidosis, is not well established. METHODS Descriptive case series of three patients with sarcoidosis and SFN. The presenting clinical features, skin biopsy results, autonomic reflex screen and quantitative sudomotor axon reflex testing (QSART) findings, and response to therapy are delineated. RESULTS We describe three patients with biopsy-proven sarcoidosis who developed intractable neuropathic pain and/or symptoms related to associated autonomic dysfunction despite treatment with various immunosuppressive medications and narcotic analgesics. QSART showed evidence of a postganglionic sudomotor abnormality in one patient and was normal in the other two. Skin biopsy findings were abnormal, demonstrating a non-length-dependent sensory SFN in all three patients. Painful neuropathic symptoms, as well as symptoms related to dysautonomia from SFN responded significantly to treatment with intravenous immunoglobulin (IVIG). CONCLUSION IVIG appears to be effective in relieving symptoms from SFN associated with sarcoidosis, suggesting an underlying immune mechanism. Larger prospective, controlled studies would be needed to confirm this response to IVIG and to further elucidate the underlying pathobiology behind this association with sarcoidosis.

Abstract
PURPOSE OF REVIEW Almost 100 years after its original description, sarcoidosis remains an enigmatic disease with unclear etiology and capricious symptomology, as well as a diagnostic challenge. This review coalesces current literature on the neuro-ophthalmic manifestations of sarcoidosis and discusses the epidemiology, etiology, clinical presentation, diagnosis, and management of this disease. RECENT FINDINGS Recent investigations strongly identify a genetic component as well as a host of candidate antigenic triggers. Certain human leukocyte antigen polymorphisms may influence not only the susceptibility of individuals to sarcoidosis but also the course of the disease. Diagnostic advances include the finding of two additional potential biomarkers of sarcoidosis as well as the use of positron emission tomography technology in localization of disease sites for biopsy. In addition to the concomitant and alternative use of immunosuppressive agents to steroid therapy, disease remission in refractory neuro-ophthalmic sarcoidosis with tumor necrosis factor alpha inhibitors has also been reported. SUMMARY Sarcoidosis can affect any part of the visual system; the most common neuro-ophthalmic presentation is optic neuropathy. Diagnosing the disease is problematic as the clinical presentation is nonspecific which may be associated with many other pathologies and no diagnostic finding is pathognomonic. In recent years, progress has been made in identifying new biomarkers and developing imaging techniques. Although corticosteroids remain the mainstay of therapy, many new pharmacological agents have been added to the treatment arsenal.

Abstract
Intra-axial pseudotumors in the central nervous system often mimic malignant brain tumors and cause difficulty in diagnosis and treatment. The present study investigates their radiologic and histological features to elucidate diagnostic clues. Six cases were included in the study, one man and five women, ranging in age from 44 to 87 years (mean age, 61 years). Histologically, three cases had demyelination, and one case each had abscess, angiitis, and non-Langerhans cell histiocytosis. All cases were evaluated radiologically on MRI, most of them by thallim-201 single photon emission tomography ((201)Tl-SPECT). These cases were examined using H&E, special stains, and immunohistochemical studies with a variety of antibodies. MRI demonstrated perifocal edema and ring-like or solid enhancement, mimicking the malignant tumors. Diffusion-weighted MRI showed a hypo-iso-intensity with a hyperintensity on the apparent diffusion coefficient. A (201)Tl-SPECT study revealed no uptake. Although there were various kinds of pathology, inflammatory cells were observed, associated with vascular proliferation and reactive astrocytosis. In addition, some cases showed demyelinating or destructive changes. These results suggested that intra-axial pseudotumors in the central nervous system contain various kinds of pathology, and detailed clinicopathological analysis is important from the point of view of differential diagnosis.

Abstract
This is a case which highlights unique diagnostic challenges in the evaluation of a previously healthy patient presenting with a myelopathy initially most concerning for malignancy. However, timely recognition and nonoperative therapy of unexpected spinal sarcoidosis with corticosteroidal therapy was crucial in averting the sequelae of undiagnosed or misdiagnosed neurosarcoidosis, which can be devastating and life-threatening. Diagnosis is challenging due to significant similarities in clinical and roentgenographic findings of spinal sarcoidosis with infection, inflammation, and malignancy. Our case demonstrates that diagnosis of spinal sarcoidosis is especially elusive when it is the initial manifestation of sarcoidosis.

Abstract
Neurosarcoidosis is a diagnostic consideration in diverse clinical settings. Efforts should be made to secure pathologic confirmation of systemic sarcoidosis; only rarely is central nervous system (CNS) pathologic confirmation available. CNS infection and malignancy should be reasonably excluded before making a diagnosis of CNS sarcoidosis. Corticosteroid therapy alone may not be sufficient to treat neurosarcoidosis; adjunct immunosuppressive agents are increasingly used to achieve an optimal clinical outcome.
