Chanpura A, Gupta RK, Sriwastava SK, Rahmig J. Diagnostic value of soluble Interleukin-2 receptor in patients suffering neurosarcoidosis: A systematic review. J Cent Nerv Syst Dis 2024; 16:11795735241274186. [PMID: 39193252 PMCID: PMC11348353 DOI: 10.1177/11795735241274186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 06/16/2024] [Accepted: 07/17/2024] [Indexed: 08/29/2024] Open
Abstract
Background Neurosarcoidosis is an inflammatory granulomatous disease. Up to 25% of occult sarcoidosis affecting the nervous system are only detected by autopsy. In addition, in recent years the suspicion arose that the soluble Interleukin-2 Receptor (sIL-2R) might be useful in differentiating between neurosarcoidosis and neurosarcoidosis-like diseases such as neurotuberculosis, multiple sclerosis, or cerebral lymphoma. Objectives Therefore, we aimed to systematically review randomized controlled trials (RCT), observational studies, and case-control studies evaluating sIL-2R levels in neurosarcoidosis patients. Design For this systematic review, a comprehensive literature search of electronic databases including EMBASE, The Web Of Science, The Cochrane Library, MEDLINE, and Google Scholar was conducted. The search was limited to the English language and publication date up to January 08th, 2024. Data Sources and Methods As part of the search strategy conducted, 6 articles met the inclusion criteria. Two independent reviewers extracted the relevant data from each article. In addition, 2 independent reviewers assessed the quality of each study using the Newcastle-Ottawa Scale (NOS). Results We included 6 studies comprising 98 patients suffering from neurosarcoidosis, 525 non-sarcoidosis patients, and 118 healthy controls. Included studies were published between 2010 and 2023. Cerebrospinal fluid (CSF) sIL-2R levels differed significantly between neurosarcoidosis patients and multiple sclerosis, vasculitis, and healthy controls whereas serum sIL-2R levels did not reveal sufficient discriminative power. sIL-2R index was able to discriminate neurosarcoidosis from neurotuberculosis, bacterial/viral meningitis, and healthy controls. Conclusions In this systematic review, we found indications that sIL-2R may be a useful biomarker for the diagnosis of neurosarcoidosis. To determine an additional diagnostic value of sIL-2R, large prospective studies are needed that not only examine absolute sIL-2R levels in serum or CSF but also the dynamic changes as well as the implications of renal function on sIL-2R levels.

Challenges in diagnosis and management of adult spinal cord gliomas. Rev Neurol (Paris) 2021; 177:515-523.

Abstract
Intramedullary spinal cord gliomas have very low incidence rates. They are associated with difficulties in diagnosis and treatment, and cause significant morbidity. Their clinical presentation and their appearance at magnetic resonance imaging are not specific. They can mimic inflammatory, infectious, vascular disorders or other neoplastic lesions. Primary treatment is surgery. Surgical resection can often be total for ependymomas, but difficult for infiltrating astrocytomas. Radiotherapy is indicated for malignant tumors, but remains controversial in some indications. Chemotherapy is reserved for recurrence, but small retrospective series are available. Genetic studies have revealed genetic alterations which could have a potential impact on treatment in the near future.

Abstract
Background Patients with biopsy-proven systemic sarcoidosis who develop a chronic CNS disorder are often presumed to have neurosarcoidosis (NS), however, the possibility of comorbid neurologic disease, such as MS, must be considered if presentation and course are not typical for NS. Methods Retrospective chart review across 4 academic MS centers was undertaken to identify patients with diagnosis of MS (2017 McDonald criteria) and biopsy-confirmed extraneural sarcoidosis. Data were abstracted from each chart using a case report form that systematically queried for demographic, clinical, and paraclinical characteristics relevant to NS and MS. Results Ten patients met our inclusion criteria (mean age 47.7 [±5.9] years; 80% female). Noncaseating granulomas consistent with sarcoidosis were found on biopsy in all cases (lung 7/10, mediastinum 2/10, liver 1/10, spleen 1/10, and skin 1/10). Diagnosis of MS was based on clinical history of MS-like relapses and MRI findings characteristic of demyelination and typical disease evolution during follow-up (average of 7 years). No patient developed features of NS that could be considered a "red flag" against the diagnosis of MS (such as meningeal enhancement, hydrocephalus, and pituitary involvement). All patients were treated with disease-modifying therapy for MS. Conclusions We propose a rational diagnostic approach to patients with sarcoidosis who may have comorbid MS. When the clinical picture is equivocal, the presence of multiple "MS-typical lesions" and the absence of any "NS-typical lesions" on MRI favor diagnosis of MS. Close follow-up is required to ascertain whether clinical and radiologic disease evolution and response to MS therapies conform to the proposed diagnosis of MS.

Abstract
Purpose: Despite the huge advance in diagnostic technics, about one-third of uveitis is still considered of unknown etiology. In this study, we aimed to report their clinical features and to describe how a diagnosis has been finally reached for some patients.Methods: We retrospectively reviewed all patients with uveitis referred to our tertiary center between 2002 and 2016. The unknown etiology was admitted after a new ophthalmologic examination and a full work-up in internal medicine in our tertiary center.Results: Among 957 patients with uveitis, 355 had uveitis of unknown etiology. The clinical and epidemiological characteristics of this subgroup were no different from those with a known etiology. Out of 104 patients who were followed-up for more than 1 year, a diagnosis was finally achieved in 20 patients. The diagnosis was determined either because of the occurrence of a new clinical symptom (n = 10), a new/repeated non-ophthalmologic investigation (n = 7), or a new/repeated ophthalmic exam (n = 3).Conclusion: A prolonged follow-up, with repeated exams, may allow the determination of an etiology in about one-fifth of uveitis initially considered as idiopathic.

Abstract
Sarcoidosis is a disease with heterogeneous manifestations and outcomes, varying in part on the basis of organ involvement. Specifically, patients with sarcoidosis at risk for poor outcomes include individuals with treatment-resistant pulmonary sarcoidosis, including fibrotic pulmonary disease and pulmonary hypertension, as well as those with cardiac, neurologic, and multiorgan disease. The limited but available data relating to these patients with high-risk sarcoidosis, defined as those patients with presentations requiring medical intervention to avoid progressive disability or premature death, was evaluated as part of the National Heart, Lung, and Blood Institute's workshop to improve understanding of these disease manifestations. In particular, knowledge gaps that preclude a greater understanding of the pathogenesis and management of these severe sarcoidosis clinical phenotypes were identified in the workshop. Research strategies are proposed to address critical knowledge gaps that would further our understanding of these disease manifestations and enhance the care of these patients.

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
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
A differential diagnosis between neurosarcoidosis and neurosyphilis is particularly problematic in patients with a positive serologic result for syphilis. We report here a patient with a solitary cavernous sinus sarcoidosis who had a history of syphilis and showed rapidly progressing cavernous sinus syndrome. A transsphenoidal biopsy was performed and a histopathologic examination revealed a non-caseating granuloma with an asteroid body. His facial pain disappeared after steroid therapy. He received oral prednisolone for one year. A follow-up magnetic resonance imaging of the brain revealed resolution of the mass over the cavernous sinus. Particularly in patients with a history of syphilis, neurosyphilis should be included in a differential diagnosis of neurosarcoidosis.

Abstract
This study reports a previously healthy, immunocompetent adult male in whom human herpesvirus 7 (HHV-7) DNA was detected continuously from the cerebrospinal fluid (CSF). This patient developed definite sarcoidosis with primary symptomatic manifestations in the central nervous system (CNS). The initial presentation was with loss of visual acuity and papilledema. Brain MR imaging at presentation confirmed papilledema, but otherwise there were no focal abnormalities or signs of hydrocephalus. CSF investigation revealed pleocytosis and elevated protein levels. HHV-7 DNA was detected repeatedly from CSF but not from blood over 1 year follow-up. High resolution computed tomography of lungs was normal. Positron emission tomography showed several metabolically active lymph nodes in the mediastinum, and the histopathological investigation revealed granulomatous inflammation consistent with sarcoidosis. The finding of HHV-7 DNA in the CSF in the context of neurosarcoidosis has not been reported previously. The detection of HHV-7 DNA may result from the selective activation of CD4+ T-lymphocytes in the CSF caused by neurosarcoidosis. Further studies are needed to establish whether the detection of HHV-7 DNA in the CSF in association with neurosarcoidosis represents a clinically significant HHV-7 CNS infection.

Abstract
A 79-year-old woman was admitted complaining of progressive weakness and numbness of the right hand. The patient was otherwise healthy. The patient's history was unremarkable. Clinical and electrophysiological examination revealed a compression of the ulnar nerve in the ulnar sulcus and in Guyon's canal. Ultrasound evaluation showed a suspicious tumour proximal to the elbow close to the ulnar nerve. The ulnar sulcus was then released and an epineural and perineural lesion 3-4 cm proximal to the sulcus was excised under microscope. The histopathology confirmed the lesion as non-caseating sarcoid granulomas. The patient showed no other signs of systemic sarcoidosis, as neuropathy was the only symptom and the condition improved postoperatively. Sensory deficits and paraesthesia resolved fully. The extension of the minor finger remained slightly inferior compared with the not affected side. Sarcoid neuropathy is a rare neurological complication of sarcoidosis and has to be included in differential diagnosis of nerve conduction impairments.

Abstract
OBJECTIVE Intramedullary spinal sarcoidosis is a difficult diagnosis to make because of its nonspecific clinical and imaging features and its imitation of other common spine disorders. We present a patient with intramedullary spinal sarcoidosis that mimicked spinal cord injury from a cervical disk herniation. METHODS Relevant information was extracted from the patient's medical and imaging records. A thorough literature review subsequently was performed. RESULTS A 59-year-old woman presented to our institution with several months of intermittent parathesias, pain, and subjective weakness in her right upper and lower extremities. Magnetic resonance imaging of the cervical spine demonstrated a large osteophyte-disk complex at C4-5 adjacent to a small area of intramedullary spinal cord enhancement. The patient underwent C4-5 anterior cervical diskectomy and fusion for the osteophyte-disk complex. She initially improved postoperatively but subsequently worsened after a few months. Because of more prominent spinal cord enhancement, a posterior laminectomy and biopsy of the enhancing lesion was performed. Intramedullary spinal sarcoidosis was diagnosed, and she was treated medically with steroids and immunosuppressive agents. CONCLUSION Spinal sarcoidosis can mimic more common disease processes, such as cervical spondylosis. It is an important consideration in the diagnosis of intramedullary or intradural lesions of the spinal cord because early medical treatment may improve the course of the disease process. Surgery should be limited to biopsy for diagnostic purposes.

Abstract
INTRODUCTION Neurosarcoidosis accounts for approximately 5% of cases of sarcoidosis. OBJECTIVE To determine the frequency of Neurosarcoidosis in our setting and analyze the clinical-radiological findings and evolution of 30 patients consecutively diagnosed. METHODS The medical records of patients with a diagnosis of Neurosarcoidosis were reviewed, and data regarding the clinical features, ancillary tests performed, treatment, and outcome were recorded. We revised the literature to summarize and discuss the previous clinical series of Neurosarcoidosis. RESULTS It accounted for 6.7% of all cases of sarcoidosis. Seven patients had definite diagnosis and 23 had probable diagnosis. The mean age at onset of Neurosarcoidosis was 48.3 years and 66.7% of patients were women. Neurologic clinical features were the first manifestation of Neurosarcoidosis in 70% of cases. Cranial neuropathy was present in 17 patients and 14 of them had facial palsy. The central nervous system was affected in 10 patients and the peripheral nervous system in 5. Chest disease, the most common extraneurologic manifestation, was present in 20 patients. All patients were treated with corticosteroids, and all those with central nervous system involvement had poor outcome. CONCLUSION Neurosarcoidosis requires a high degree of suspicion to establish the diagnosis. Central nervous system involvement is associated with a poor prognosis.

Abstract
OBJECTIVE To report on the clinical presentations, laboratory abnormalities, treatment and outcomes in 54 patients with neurosarcoidosis (NS). BACKGROUND Sarcoidosis is an inflammatory granulomatous disease affecting multiple organ systems. Neurosarcoidosis (CNS involvement) is seen in approximately 25% of patients with systemic sarcoidosis, although it is subclinical in most of these cases. Because of its rarity, exposure of neurologists to the clinical spectrum of NS is limited to case reports or short case series. PATIENTS AND METHODS A database of 3900 patients treated at the Vanderbilt Multiple Sclerosis Clinic between 1995 and 2008 was searched for 'neurosarcoidosis', 'neurosarcoid', 'sarcoidosis' and 'sarcoid'. Of the 162 patient records that were retrieved, 54 patients were found to meet the criteria for definite, probable or possible neurosarcoidosis and were reviewed, including their clinical presentation, Cerebrospinal fluid (CSF) findings, Magnetic resonance imaging (MRIs), biopsy results, treatment, and where available, outcomes 4 months to 20 years after onset of the presenting illness. RESULTS Clinical presentations and imaging findings in NS were varied. Cranial nerve abnormalities were the most common clinical presentation and involvement of the optic nerve in particular was associated with a poor prognosis for visual recovery. Isolated involvement of lower cranial nerves had a more favorable outcome. T(2) hyperintense parenchymal lesions were the most common imaging finding followed by meningeal enhancement. Long-term treatment consisted of prednisone and/or other immunomodulators (azathioprine, methotrexate or mycophenolate mofetil). CONCLUSION Unlike systemic sarcoidosis, there is difficulty in making tissue diagnosis when involvement of CNS is suspected. MRI and CSF studies are sensitive in the detection of CNS inflammation but lack specificity, making the ascertainment of neurosarcoidosis a clinical challenge. In addition the low prevalence of the disease makes clinical trials difficult and therapeutic decisions are likely to be made from careful reporting from case studies.

Abstract
Neurosarcoidosis is an uncommon clinical entity, even in patients with systemic sarcoidosis. Its presentation is widely varied but longitudinally extensive transverse myelitis secondary to neurosarcoidosis has only rarely been described. We report the case of a patient with pulmonary sarcoidosis and congenital immunosuppression who developed longitudinally extensive transverse myelitis secondary to neurosarcoidosis following splenectomy. Diagnosis was based on history, inflammatory changes on MRI, and cerebrospinal fluid findings. Standard therapy with intravenous steroids was unsuccessful. Only more novel treatment with Infliximab allowed improvement.

Abstract
Sarcoidosis is a chronic multi-system granulomatous disorder of unknown etiology. Central nervous system involvement is relatively uncommon in sarcoidosis. Clinical manifestations and radiological appearances of neurosarcoidosis vary widely depending on the site and activity of the lesions. In most cases, the imaging appearance is nonspecific. We report a very rare case of extensive neurosarcoidosis with progressively enlarging cystic lesions in the right temporal lobe.

Abstract
✓ Sarcoidosis is a multisystemic granulomatous disease characterized by noncaseating epithelioid granulomata that affects the lung in over 90% of patients and the central nervous system (CNS) in 5–9%. Neurosarcoidosis often occurs as multifocal meningeal and parenchymal lesions, and its diagnosis is particularly difficult in the absence of concomitant systemic disease. Hypothalamic-pituitary sarcoidosis occurs in fewer than 10% of patients with neurosarcoidosis and has been previously reported in association with profound endocrinological dysfunction. The authors report the case of a patient with isolated pituitary sarcoidosis who was first evaluated for visual symptoms and showed no preoperative endocrinological dysfunction or evidence of multisystemic or other CNS involvement. To the authors' knowledge, only 1 other such presentation is previously reported in the English literature. Such presentations are diagnostically and therapeutically challenging, and definitive diagnosis requires obtaining a biopsy specimen of the lesion with histological proof of noncaseating epithelioid granuloma, as well as the exclusion of other possible entities.

Abstract
INTRODUCTION The spinal localization is rare for neurosarcoidosis (0.43 percent of cases) but can be the inaugural manifestation of the disease. We report two cases of spinal neurosarcoidosis in a 57-year-old man and a 43-year*old woman with uneventful past medical histories. Both presented progressive myelopathic features. METHODS Magnetic resonance imaging (MRI) of the spine demonstrated intramedullary lesions, dorsal in the first case, and cervical in the second case. Serum angiotensin converting enzyme was elevated. Radiographs of the chest revealed bilateral symmetric hilar mediastinal lymphadenopathy in the first patient, and bronchial biopsy demonstrated non caseating granulomas. In the second patient the diagnosis was made on pathological examination of a minor salivary gland biopsy. RESULTS The patients received corticosteroid therapy with good response in the second patient. CONCLUSION The diagnosis of intramedullary sarcoidosis is difficult without a previous diagnosis of systemic sarcoidosis or other apparent symptom(s). Extraneurologic biopsies may be suggestive. We reviewed the literature on the diagnosis and treatment of intramedullary sarcoidosis.

Abstract
BACKGROUND Neurosarcoidosis is a rare manifestation of sarcoidosis. Involvement of the nervous system in sarcoidosis can range from peripheral or cranial neuropathy to central nervous system disease. Cauda equina sarcoidosis is distinctly rare. REVIEW SUMMARY The authors present a 58-year-old patient with systemic sarcoidosis who developed cauda equina and conus medullaris syndrome. Seventeen previous published cases of cauda equina sarcoidosis are reviewed. The history of systemic sarcoidosis, cerebrospinal fluid characteristics of lymphocytic pleocytosis with elevated protein, and evidence of acute denervation by needle electromyography are helpful in the diagnosis of this condition. Early diagnosis and treatment of cauda equina sarcoidosis usually provide a rapid recovery and yield a good prognosis. CONCLUSION Although rare, sarcoidosis should be considered in the differential diagnosis of cauda equina syndrome, particularly in patients with unclear etiology.

Abstract
PURPOSE To describe a patient with a long disease history who was finally diagnosed with neurosarcoidosis and to discuss the reasons behind the delayed diagnosis. CASE REPORT A 58-year-old man with sick sinus syndrome and bradycardia, which was treated with a pacemaker, developed first right and then left facial palsy. Subsequently, multiple cranial nerve palsies developed and later spontaneously resolved. Neurosarcoidosis was suspected at that stage, but excluded because the patient had no typical sarcoid lung changes, his serum and cerebrospinal fluid angiotensin converting enzyme activity levels were normal and a computed tomography scan disclosed no central nervous system changes. During follow-up, the patient developed extremely dry eyes and mouth, suggesting Sjögren's syndrome. Rheumatology consultation did not reveal any autoimmune or visceral features typical of Sjögren's syndrome and autoantibodies were negative. However, both labial salivary gland and conjunctival biopsies revealed non-caseating granulomas, and neurosarcoidosis was diagnosed. CONCLUSIONS Neurosarcoidosis is a relatively rare disease with a somewhat poor longterm prognosis in one-third of cases, although the neurological manifestations often diminish or disappear in response to glucocorticoid treatment. Diagnosis is often a clinical challenge, especially in the absence of pulmonary changes or other features typical of sarcoidosis. The labial salivary gland and conjunctiva provide helpful biopsy sites for histopathological confirmation of the diagnosis.

Abstract
Up to 70% of patients with systemic sarcoidosis developing neurosarcoidosis do so within the first 2 years of their systemic illness. Central nervous system (CNS) involvement as the only manifestation of sarcoidosis can be seen both at first time of disease and at recurrence in a few isolated cases. A young man showed neurological symptoms caused by isolated CNS sarcoidosis after unsuccessful treatment of primary pulmonary sarcoidosis by steroids. MRI scans of the head showed a distinct structural lesion temporodorsal in the left hemisphere and in the left-sided basal ganglia. The diagnosis was proved by neurosurgical resection. Post-operative systemic treatment with long-term corticosteroids was ineffective. After low-dose whole-brain irradiation of the isolated CNS lesion with 20 Gy, partial resolution of the clinical features and stabilization of disease proved by MRI ensued. In neurosarcoidosis the use of radiation therapy remains an appropriate therapy option with minimal adverse sequelae if primary medical treatment fails.

Abstract
OBJECTIVE We present a rare case of neurosarcoidosis mimicking an intramedullary tumor in the medulla oblongata. The features of the clinical presentation, magnetic resonance (MRI) appearances, and management strategy are discussed. CASE PRESENTATION A 59-year-old man without evidence of systemic sarcoidosis was presented with a history of progressive numbness and deep sensation disturbance in bilateral lower extremities. MR imaging revealed an enhanced intra-axial mass lesion on the dorsal side of medulla. Under neurophysiological monitoring, tumor biopsy was performed. Pathologic evaluation revealed noncaseating granuloma composed of large epithelioid cells with multinucleated giant cells, suggesting sarcoidosis. Findings of comprehensive hematologic laboratory studies; cerebrospinal fluid examination; and examinations for bacteria, fungi, and acid fast bacilli were all negative. This mass lesion was diagnosed as medullary neurosarcoidosis, and then high-dose steroid therapy was tried. On follow-up, nearly complete resolution of the neurosarcoidosis on MRI was revealed. CONCLUSION To our knowledge, this is the first reported case of neurosarcoidosis manifested in the medulla oblongata. A biopsy is sufficient for a diagnosis and high-dose steroid is recommended.

Abstract
OBJECTIVE To describe a group of patients with neurosarcoidosis and to highlight diagnostic difficulties based on current diagnostic criteria. METHODS The patient database of a general neurological department was searched for patients with established or suspected diagnosis of neurosarcoidosis. Twenty-four patients were identified with definite (n = 3), probable (n = 10) and possible neurosarcoidosis (n = 10). History and clinical, laboratory and imaging data of patients with definite and probable neurosarcoidosis were analyzed. RESULTS Cranial nerve symptoms were a dominant clinical feature, with the optic nerve being affected most frequently. Cerebrospinal fluid pleocytosis was found in more than half of the patients. Intrathecal IgG synthesis and oligoclonal bands were less frequent. There was a wide array of MRI lesions in both groups. Chest X-ray was false negative in 2 of 5 patients who also underwent a thoracic CT. Therapy with prednisolone was initiated in all patients. After a median of 36 months, 6 of 8 patients with follow-up data of >24 months were still in remission. Aggravation of symptoms required therapy escalation in 2 patients. CONCLUSION There is a wide range of clinical symptoms and test results in patients with "definite" or "probable" neurosarcoidosis. Because systemic involvement is a crucial diagnostic criterion, extensive medical work-up may be necessary. Prognosis under corticosteroid treatment may be better than previously thought.

Abstract
BACKGROUND Sarcoidosis is a multisystemic disease of unknown etiology. The presentation and frequency of different organ involvement can vary according to race, geographical location and gender. Because of the multiorgan involvement and its mimicking nature, the diagnosis is usually a challenge, even to specialists. Therefore, knowledge of the epidemiologic features of the disease is important. METHODS The first case report of sarcoidosis in Turkey was published in 1954. We obtained data from case series by hand searching of journals and congress abstract books on pulmonary medicine between 1954 and 2000. Series of 5 or more cases were included in our compilation of data. RESULTS Data for 1327 patients with the diagnosis of sarcoidosis were obtained from 29 reports. There were nearly twice as many females as males with the disease in these case series. Most of the patients were at stage 1 or 2 at the time of diagnosis. Peripheral lymph node enlargement was reported in 119 patients, skin involvement in 22 and nervous system involvement in 12 patients. Erythema nodosum was reported in 137 patients. Serum angiotensin-converting enzyme was elevated in 52% and the tuberculin skin test was positive in 24% of patients. Organ biopsies seemed to be the preferred diagnostic method in the initial papers while recent papers revealed the value of obtaining a bronchoscopic biopsy. CONCLUSION Despite several limitations of our study, this is the first compilation of 46 years of data on sarcoidosis in Turkey. Further studies on the geographical distribution and incidence and prevalence are needed for our country.

Abstract
Antibodies against myelin oligodendrocyte glycoprotein (MOG) mediate demyelination in experimental autoimmune encephalomyelitis (EAE) in different animal species and are implicated in the immunopathogenesis of multiple sclerosis (MS). In order to evaluate the anti-MOG response, we have analyzed the cerebrospinal fluids (CSFs) from 44 MS patients and 51 controls, 11 with other inflammatory neurological disorders (OIND) and 40 with non-inflammatory neurological disorders (NIND). The frequency of anti-MOG antibodies positive patients in the MS group (30%) was significantly higher compared to the NIND (8%, p=0.02), but not compared to the OIND group (55%, p=0.228). Interestingly, all six patients with neurosarcoidosis had MOG-specific antibodies in their CSF. Frequency of anti-MOG antibodies was similar in patients with clinically active and stable MS (32% and 26%, respectively; p=0.921). However, in clinically active MS patients, antibody titers were higher in comparison with patients with stable disease, although the difference did not reach the level of statistical significance (p=0.06). These results further support the potential role of anti-MOG antibodies in the immunopathology of MS in the subset of patients with this disease. Furthermore, our findings suggest for the first time that anti-MOG antibodies could be an accessory diagnostic tool in neurosarcoidosis.

Abstract
Neurosarcoidosis is a great mimicker. It is often difficult to diagnose particularly when there is no prior history of systemic sarcoidosis. Although certain sites of the neuraxis are more commonly involved than others, any site of the central or peripheral nervous system can be affected. We report a case of sarcoidosis involving the cauda equina in a 38-year-old African American male without prior history of systemic disease. Initial clinical presentation was suggestive of Guillian-Barré syndrome, but the evaluation proved this case to be neurosarcoidosis involving the cauda equina. We have followed this patient for 8 years, and he remains clinically stable on prednisone 5 mg/day.

Abstract
The involvement of the hypothalamus and/or pituitary gland by granulomatous, infiltrative or autoimmune diseases is a rare condition of non-tumoral-non-vascular acquired hypothalamic dysfunction and hypopituitarism. In this paper, we present the case of a 26-year-old woman, who showed an amenorrhea-galactorrhea syndrome with hypogonadotropic hypogonadism due to an isolated hypothalamic-peduncular localization of neurosarcoidosis. Acquired GH deficiency was also demonstrated. This clinical case provided the opportunity for a review of the endocrine aspects linked to brain infiltrative diseases that may affect the hypothalamic-pituitary function, with a focus upon neurosarcoidosis. Sarcoidosis is a pathogen-free granulomatous disease that affects both the central and peripheral nervous system in 5-16% of patients. In most cases, such involvement by sarcoidosis occurs within a multi-systemic disease, but disease localization limited to the nervous system may also be observed. Endocrine manifestations of neurosarcoidosis disclose "chameleon-like" clinical pictures, which are usually expressed by the evidence of hypothalamic dysfunction, diabetes insipidus, adenopituitary failure, amenorrhea-galactorrhea syndrome, in isolated fashion or variedly combined. More rarely, inappropriate anti-diuretic hormone secretion, isolated secondary hypothyroidism, adrenal insufficiency or altered counter-regulation of glucose homeostasis have been reported. Neurosarcoidosis is often hard to diagnose, especially when the neurological localization of the disease is not accompanied by other systemic localizations or by specific signs of the disease, and when the lesion is too deep to obtain bioptic confirmation. The study of cerebrospinal fluid and blood lymphocyte sub-populations, integrated by MRI and nuclear scans (67GalIium uptake and 111Indium-pentetreotide, Octreoscan), may be helpful for a correct diagnosis. Therapy with corticosteroid and immunosuppressive drugs, such as cyclosporine A, and other treatment approaches to neurosarcoidosis are also accounted for.

Abstract
Sarcoidosis is multisystem granulomatous disease of unknown etiology. Although the nervous system is involved in only 5% to 16% of patients, neurosarcoidosis is one of the more serious manifestations of the disease. Cranial neuropathies are common, but involvement of the mininges or the brain or spinal cord parenchyma causes more severe morbidity. MR imaging of affected portions of the neuraxis is a very sensitive diagnostic technique. Treatment with corticosteroids is the mainstay of therapy.
