Abstract
ABSTRACT We present a case of sarcoidosis with a rare presentation of involvement of peripheral nerves of the lower limbs and subcutaneous nodules detected on 18 F-FDG PET/CT. The patient also had involvement of the spinal nerves and dura, histologically proven to be sarcoidosis. There were other manifestations of systemic sarcoidosis like metabolically active cervical and mediastinal lymphadenopathy. This case highlights the role of 18 F-FDG PET/CT in evaluating the uncommon sites of sarcoid involvement. Although many cases of sarcoid involvement of central nervous system have been reported, peripheral nerves involvement in the extremities was not found on a literature search.

Abstract
A 70-year-old female presented with bilateral numbness in her upper limbs. She was diagnosed with cervical spondylotic myelopathy and underwent cervical laminoplasty. However, there was no significant improvement in sensory disturbance, and at 6 months after surgery, she developed subacute motor and gait disturbance in four extremities. Spinal MRI revealed a long lesion of the spinal cord with edema, and a part of the lesion showed gadolinium contrast enhancement. Bronchoscopy revealed an elevated CD4/8 ratio, and gallium scintigraphy demonstrated an accumulation in the hilar lymph nodes, leading to a diagnosis of neurosarcoidosis. In case of rapid deterioration during the course of cervical spondylotic myelopathy, neurosarcoidosis should be considered as a differential diagnosis, which can be assessed by contrast-enhanced MRI.

Abstract
The occurrence of cerebral vasculitis in individuals with neurosarcoidosis (NS) is considered to be rare. Although the number of relevant publications has increased in recent years, evidence is mostly limited to case reports. To obtain a better understanding of this rare and severe manifestation of disease, we carried out a scoping review on cerebral vasculitis in patients diagnosed with NS. The results of the review indicate that the diagnosis of cerebral vasculitis in patients with NS is made especially in patients with systemic sarcoidosis. However, recurrent strokes in patients with NS remains the main indicator of cerebral vasculitis. A tissue biopsy is considered the gold standard to confirm the diagnosis despite occasional false-negative results. Glucocorticoids and steroid-sparing agents are the most successful current treatments. Favorable outcomes were observed with strategies targeting TNFα and B cells. The goal of this review is to summarize the current literature and treatment options for cerebral vasculitis in patients with NS.

Abstract
Neurosarcoidosis is a complex and multifaceted inflammatory disorder affecting the nervous system. The disease, characterized by non-caseating granulomas, primarily involves the central and peripheral nervous systems. Neuro-logical manifestations vary widely and can include cranial nerve palsies, meningeal involvement, parenchymal lesions, hydrocephalus, and more. Diagnosis remains challenging due to the lack of specific imaging features, necessitating a combination of clinical evaluation, cerebrospinal fluid analysis, imaging studies, and sometimes tissue biopsy. This review article underscores the importance of the identification of various imaging features to mitigate the mortality and morbidity associated with neurosarcoidosis.

Abstract
Central nervous system vasculitis (CNSV) is a group of disorders leading to inflammatory vasculopathy within the brain, spinal cord, and leptomeninges. CNSV is divided into primary angiitis of the central nervous system (PACNS) and secondary CNSV based on the underlying etiology. PACNS is a rare inflammatory disorder with poorly understood pathophysiology and heterogeneous and highly variable clinical features. The diagnosis depends on a combination of clinical and laboratory variables, multimodal imaging, and histopathological examination as well as exclusion of mimics. Several systemic vasculitides, infectious etiologies and connective tissue disorders have been shown to cause secondary CNSV and require prompt recognition.

Abstract
PURPOSE OF REVIEW Neurosarcoidosis is a rare manifestation of sarcoidosis that is challenging to diagnose. Biopsy confirmation of granulomas is not sufficient, as other granulomatous diseases can present similarly. This review is intended to guide the clinician in identifying key conditions to exclude prior to concluding a diagnosis of neurosarcoidosis. RECENT FINDINGS Although new biomarkers are being studied, there are no reliable tests for neurosarcoidosis. Advances in serum testing and imaging have improved the diagnosis for key mimics of neurosarcoidosis in certain clinical scenarios, but biopsy remains an important method of differentiation. Key mimics of neurosarcoidosis in all cases include infections (tuberculosis, fungal), autoimmune disease (vasculitis, IgG4-related disease), and lymphoma. As neurosarcoidosis can affect any part of the nervous system, patients should have a unique differential diagnosis tailored to their clinical presentation. Although biopsy can assist with excluding mimics, diagnosis is ultimately clinical.

Abstract
Vasculitis in neurosarcoidosis is rare, with only a few cases reported in the literature. We report the clinical observation of a 51-year-old patient with no previous medical history, who was admitted to the emergency department due to sudden onset confusion, fever, sweating, weakness, and headaches. The first brain scan was normal, but a further biological exam with a lumbar puncture revealed lymphocytic meningitis. A complementary cerebral MRI revealed abnormalities in the white matter signal, suggestive of multiple sclerosis, with petechial hemorrhagic foci associated with leptomeningeal involvement and cerebral vasculitis. Thoraco-abdomino-pelvic computed tomography revealed hilar and mediastinal lymphadenopathy, as well as lymph nodes in the lower cervical region. A biopsy of the lymph nodes confirmed the presence of non-caseating granulomatous inflammation consistent with sarcoidosis. High-dose corticosteroid therapy was initiated with good clinical outcomes. Cerebral vasculitis in neurosarcoidosis is rare but can lead to neurological complications requiring long-term multidisciplinary management.

Abstract
BACKGROUND Cerebrovascular disease is rarely reported in neurosarcoidosis and constitutes one of its least well-described forms, though recognition for it has grown in the last decade with recent studies estimating a higher frequency of occurrence than previously known. METHODS Patients with ischemic stroke were included if the mechanism was directly attributable to sarcoidosis of the CNS. Patients were excluded if an alternative stroke etiology was of equal or higher likelihood than CNS sarcoidosis. RESULTS Neurologic disease was the initial presenting manifestation of sarcoidosis in 8/11 (72.7%), and ischemic stroke was an inaugural manifestation of sarcoidosis in 4/11 (36.4%). Small vessel disease was the predominant ischemia subtype (10/11, 90.9%) with pontine perforating vessels (6/11, 54.5%) and lenticulostriate arteries (3/11, 27.3%) being the vasculature most often affected. Vessels with a more rostral supratentorial distribution were uncommonly affected. Common neuroinflammatory accompaniments included leptomeningitis (10/11, 90.9%) and cranial nerve disease (3/11, 27.3%). Recurrent strokes occurred in 8/11 (72.7%), and recurrent neuroinflammation occurred in 7/11 (63.6%). Antiplatelet drugs were used in 6/11 (54.5%) patients. Most (10/11, 90.9%) required at least two lines of immunosuppression to achieve inflammatory disease remission in this context; infliximab was the most successfully employed immunosuppressant (7/8 treatment courses, 87.5%). Recurrent strokes occurred in 8/11 (72.7%) patients, and a second inflammatory attack occurred in 7/11 (63.6%) patients. The presenting median modified Rankin Scale score of 4.0 improved to 2.0 over a median period of follow-up of 52.0 months. CONCLUSION Ischemic strokes in neurosarcoidosis occur in a caudal-to-rostral distribution, tend to affect small caliber blood vessels that lack collateral blood flow, and typically associate with inflammatory leptomeningeal disease. The risk for relapse in the forms of stroke or neuroinflammation are high in this neurosarcoidosis phenotype.

Abstract
This report explores the case of a 49-year-old African American male with a six-month history of multifocal neurological deficits who presented to an outside hospital after a generalized seizure. Patient was transferred to our tertiary medical center after brain imaging showed multiple bilateral supratentorial intraparenchymal hemorrhages (IPH). A brain biopsy confirmed parenchymal and perivascular non-caseating granulomas with vasculitis. The patient was definitively diagnosed with neurosarcoidosis (NS) and his condition improved with high dose corticosteroids and additional immunosuppressive therapies. Intracranial hemorrhage in the setting of NS is extremely rare, with fewer than thirty documented cases; however, this is likely an underestimation of its true prevalence. This case illustrates the difficulty in diagnosis as many other etiologies of IPH must be considered. Additionally, the clinical course and manifestations of NS is often quite variable. The uniqueness of this case lies in the rapid progression from seemingly incidental microhemorrhages to multiple large IPHs over two months. While the cause of this progression is not immediately apparent, a possible cause may be inadequate initial treatment due to delayed diagnosis. Our case demonstrates the importance of early recognition and initiation of immunosuppressive therapy, potentially leading to dramatic clinical improvement, as seen in this patient.

Abstract
Although often regarded as a protean illness with myriad clinical and imaging manifestations, neurosarcoidosis typically presents as recognizable syndromes that can be approached in a rational, systematic fashion. Understanding of neurosarcoidosis has progressed significantly in recent years, including updated diagnostic criteria and advances in treatment. The diagnosis of neurosarcoidosis is established by the clinical syndrome, imaging and histopathological findings, and exclusion of other causes. Mounting evidence supports the use of tumor necrosis factor inhibitors as an important addition to the therapeutic armamentarium, along with glucocorticoids and steroid-sparing cytotoxic immunosuppressants. In this narrative review, we summarize recent advances in the diagnosis and treatment of neurosarcoidosis.

Abstract
BACKGROUND AND OBJECTIVES Cerebrovascular manifestations in neurosarcoidosis (NS) were previously considered rare but are being increasingly recognized. We report our preliminary experience in patients with NS who underwent high-resolution vessel wall imaging (VWI). METHODS A total of 13 consecutive patients with NS underwent VWI. Images were analyzed by 2 neuroradiologists in consensus. The assessment included segment-wise evaluation of larger- and medium-sized vessels (internal carotid artery, M1-M3 middle cerebral artery; A1-A3 anterior cerebral artery; V4 segments of vertebral arteries; basilar artery; and P1-P3 posterior cerebral artery), lenticulostriate perforator vessels, and medullary and deep cerebral veins. Cortical veins were not assessed due to flow-related artifacts. Brain biopsy findings were available in 6 cases and were also reviewed. RESULTS Mean patient age was 54.9 years (33-71 years) with an M:F of 8:5. Mean duration between initial diagnosis and VWI study was 18 months. Overall, 9/13 (69%) patients had vascular abnormalities. Circumferential large vessel enhancement was seen in 3/13 (23%) patients, whereas perforator vessel involvement was seen in 6/13 (46%) patients. Medullary and deep vein involvement was also seen in 6/13 patients. In addition, 7/13 (54%) patients had microhemorrhages in susceptibility-weighted imaging, and 4/13 (31%) had chronic infarcts. On biopsy, 5/6 cases showed perivascular granulomas with vessel wall involvement in all 5 cases. DISCUSSION Our preliminary findings suggest that involvement of intracranial vascular structures may be a common finding in patients with NS and should be routinely looked for. These findings appear concordant with previously reported autopsy literature and need to be validated on a larger scale.

Abstract
Patients with rheumatological diseases may present with neurological manifestations of peripheral and/or central nervous system (CNS). Symptoms may be related to underlying rheumatological disease or CNS effects of immune-modulating drugs. Early diagnosis and therapy may help prevent serious complications. Magnetic resonance imaging (MRI), given its excellent soft tissue details, is the preferred imaging modality when evaluating patients with rheumatological disease and suspected CNS involvement. We present a review of the neuroimaging manifestations of various rheumatic diseases with emphasis on the imaging findings on MRI.

Abstract
Neurosarcoidosis (NS) affects various sites of the central nervous system, including the cranial nerve, meninges, brain parenchyma, hypothalamus, and pituitary gland. NS rarely causes intracerebral vasculitis and subsequent strokes, or cerebral infarction and hemorrhage, which are associated with high mortality. Herein, we report a 71-year-old woman's case of stroke associated with NS, which showed aggressive cerebral vasculitis with brain herniation; it was resolved with corticosteroid therapy after accurate histopathological diagnosis. This case highlights the necessity of expecting NS to sometimes follow an aggressive course, presenting with vasculitis. Most patients with NS satisfactorily respond to corticosteroids, but this is not always the case. In cases of unfamiliar ischemic or hemorrhagic lesions, the possibility of NS must be considered.

Abstract
Objectives The occurrence of stroke in patients with cardiac sarcoidosis (CS) is an under-recognized entity. The objective of this study is to evaluate the clinical presentation, risk factors, etiology, temporal relationship and management of stroke in patients with CS. Methods The data of 111 patients with CS from the Granulomatous Myocarditis Registry was analyzed. Clinical data regarding the clinical presentation, risk factors for vascular disease, electrocardiogram, echocardiogram and 18 Fluorodeoxyglucose (FDG) PET-CT were extracted from the registry database. Results Among the 111 patients with CS, 8 patients (7.2%) had a history of ischemic stroke. Six of the eight patients with ischemic stroke were young (<50 years) without conventional risk factors for vascular disease. In five patients, stroke occurred prior to the diagnosis of CS. In all except one patient the ischemic stroke occurred in the anterior cerebral circulation. LV dysfunction was noted in all patients at the time of stroke, with the presence of an LV apical clot in four of the eight patients. Atrial fibrillation was documented in 2 patients. Two patients received thrombolysis and mechanical thrombectomy, while the others were treated with standard antiplatelets and statins. There was a significant improvement in the LV Ejection fraction (33.6 ± 15.2 to 49.1 ± 13.8%, p = 0.043) following immunosuppression. Two patients developed refractory HF and respiratory sepsis, respectively, and succumbed following prolonged ICU admissions. Conclusions Ischemic stroke in patients with CS can be attributed to a cardioembolic phenomenon. A high index of clinical suspicion is needed for early diagnosis and management of these patients.

Abstract
Sarcoidosis is a systemic inflammatory disorder resulting from an inappropriate immune response to ubiquitous environmental stimuli. It has a predilection for African Americans and people of Northern European countries. The classic histology is that of a non-caseating granuloma. Central nervous system involvement is a rare occurrence in sarcoidosis and even in this manifestation, the presence of vasculitis is comparatively uncommon. We present a case of a 35-year-old female, who presented with complaints of persistent headache of moderate intensity and had a violaceous plaque on nose, being treated by a dermatologist. The patient on further workup had mildly raised proteins on cerebrospinal fluid analysis. MRI brain showed multiple foci in bilateral frontoparietal regions and centrum semiovale, while digital subtraction angiography brain depicted vasculitis of small vessels of brain and complete occlusion of right internal carotid artery at its origin. Biopsy of lesion on nose was performed that showed chronic granulomatous inflammation. A diagnosis of brain vasculitis secondary to sarcoidosis was made. The patient was treated with plasmapheresis and pulse steroid therapy initially, and later on with cyclophosphamide and azathioprine. This resulted in resolution of headache and nose lesion.

Abstract
Primary angiitis of the central nervous system (CNS) is an inflammatory vasculopathy affecting the brain and spinal cord. It is a difficult diagnosis to make because of its insidious nonspecific course and its multiple mimics. This review identifies and discusses some noninfectious mimickers of primary CNS angiitis, including: reversible cerebral vasoconstriction syndrome, Sneddon's Syndrome, amyloid-beta-related angiopathy, Susac Syndrome, and neurosarcoidosis. Each condition will be reviewed in terms of epidemiology, pathology, clinical presentation, diagnostic approach, and treatment. Distinguishing these mimics from the primary angiitis of the CNS is important for proper treatment and prognosis.

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
AIM To assess the prevalence of various imaging manifestations in neurosarcoidosis (NS) patients at presentation and to explore if specific imaging findings may cluster in different sub-groups. MATERIALS AND METHODS A retrospective, dual-institution, systematic imaging review was undertaken of the magnetic resonance imaging (MRI) findings in 100 consecutive NS patients who presented over a 15-year period. Clustering analysis (k-mode) was performed to evaluate co-occurrence of imaging findings. RESULTS Non-enhancing white matter (NEWM) lesions were the most common imaging abnormality (56%), followed by leptomeningeal (47%) and pachymeningeal (32%) involvement. Other common manifestations included cranial nerve involvement (30%), parenchymal granulomas (27%), hypothalamic-pituitary-adrenal axis involvement (26%), and hydrocephalus (14%). Additionally, a higher prevalence of perivascular enhancement (23%), cerebrovascular events (including ischaemic and haemorrhagic events; 17%), and ependymal involvement (20%) were noted than recognised previously. Additional k-mode analysis was performed to explore underlying disease sub-clusters. This was evaluated for clusters varying between two though five (k=2-5). For k=4, the analysis revealed that the imaging findings may possibly be divided into disease sub-sets of four groups, each with varying distribution of imaging manifestations and clinical manifestations. CONCLUSION Overall, NEWM lesions and meningeal involvement are the most common imaging manifestations of NS. The prevalence of perivascular enhancement, cerebrovascular events, and ependymal involvement is likely higher than reported previously. Additionally, different imaging findings in NS may cluster together and imaging subtypes in NS possibly exist.

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
The present report describes the case of a 56-year-old African American man experiencing progressive disequilibrium, lower extremity weakness, difficulty walking, and hearing loss. Brain magnetic resonance imaging showed leptomeningeal enhancement. Initial differential diagnosis was broad, including malignant, infectious, and inflammatory etiologies. The cerebrospinal fluid analyses demonstrated lymphocytic pleocytosis, hypoglycorrhachia, and hyperproteinorrachia but no other abnormalities. An extensive infectious disease workup was negative. Positron emission tomography revealed hypermetabolic lymph nodes in the right mediastinum and right hilum, correlating with findings on endobronchial ultrasonography. Subsequently, image-guided fine-needle aspiration of the right upper paratracheal lymph node was performed, and biopsy studies showed noncaseating granulomatous inflammation. Based on the clinical picture, the diagnosis of neurosarcoidosis was made, and high-dose steroids were started and resulted in significant improvement.

Abstract
Vessel wall imaging (VWI) is being increasingly used as a non-invasive diagnostic method to evaluate the intra- and extracranial vascular bed. Whereas conventional vascular imaging primarily assesses the vessel lumen, VWI changes the focus of analysis toward the vessel wall. As the technical challenges of high spatial resolution, signal-to-noise ratio, and contrast-to-noise ratio and long scans times are addressed, interest in the clinical applications of this technique has steadily increased over the years. In this review, the authors will discuss the various applications of VWI as well as principles of interpretation and common imaging findings, focusing on intracranial atherosclerosis, vascular dissection, vasculitides (such as primary angiitis of the central nervous system (PACNS) and neurosarcoidosis), vasculopathies (such as reversible cerebral vasoconstriction syndrome (RCVS), cocaine-induced vasculopathy, moyamoya disease, and radiation-induced arteriopathy), aneurysms, and post-thrombectomy changes. The authors will also discuss the potential pitfalls of VWI and helpful cues to avoid being tricked.

Abstract
OBJECTIVES To describe a unique case of isolated bilateral sarcoidosis of the cerebellopontine angle as well as the related imaging in the case. To conduct a literature review of the published articles regarding sarcoidosis of the cerebellopontine angle. DATA SOURCES Representative case report from a single institution as well as PubMed and Scopus database searches. METHODS In addition to a retrospective review, all published case reports and case series of sarcoidosis involving the cerebellopontine angle from 1960 to July 2018 in the English language were reviewed. Demographic data, presenting symptoms, and outcomes were collected. RESULTS We identified 8 total cases with pertinent clinical information that were included. CONCLUSIONS Isolated neurosarcoidosis of the cerebellopontine angle is an exceptionally rare phenomenon that, on history and imaging, presents similar to more common retrocochlear pathologies. Surgery may be required in large lesions unresponsive to traditional medical therapy with immunosuppression.

Abstract
Neurosarcoidosis when encountered by neurologists most commonly presents as cranial neuropathy, peripheral mononeuropathy,polyneuropathy, myopathy, meningitis or myelopathy. There are limited reports in the current literature on the cases of neurosarcoidosis patients presenting with ischaemic stroke. We discuss a 52-year-old patient with a known previous history of cutaneous sarcoidosis presenting with an acute third nerve palsy, facial weakness and ataxia. His magnetic resonance imaging (MRI) brain demonstrated focal signal changes in the midbrain consistent with an acute ischaemic event in the region of his third nucleus, suggesting a partial Claude syndrome presentation. Cerebrospinal fluid (CSF) examination demonstrated an elevated angiotensin-converting enzyme (ACE) level. We discuss the difficulties associated with confirming a diagnosis for his presentation and consider distinctions in stroke in neurosarcoid and its management in comparison to more common causes.

Abstract
We present the clinicopathologic conference of a 34-year-old lady with history of facial palsy 14 years ago who developed new deficits of mononeuritis multiplex, maculopapular rash, pancytopenia, splenomegaly, lung involvement and cognitive decline rapidly over three years. Investigations revealed pancytopenia, reversal of albumin globulin ratio, mediastinal adenopathy, ANA positivity, low C3 levels with the CSF being inflammatory and MRI showing extensive hemorrhagic lesions with mass effect. She had a rapidly progressive fatal course over three years with the disease being undiagnosed. This case was presented in the annual meeting of the Indian Academy of Neurology in September 2018.

Abstract
PURPOSE Spinal sarcoidosis, referring to involvement of the spine in sarcoidosis, is relatively rare and may mimic other neurological disease affecting the spine. The authors present a clinic radiological review of 18 spinal sarcoidosis patients who presented to a tertiary hospital, with emphasis on initial imaging and radiological response to treatment. MATERIALS AND METHODS We retrospectively reviewed our departmental imaging archives over a 15-year period and found 49 cases of neurosarcoidosis out of which 18 patients had spinal magnetic resonance imaging. RESULTS Approximately 72% (13/18) of the neurosarcoidosis patients showed some form of spinal involvement. The clinical, epidemiological and imaging data were reviewed for these 13 patients at presentation and follow-up. The findings on magnetic resonance imaging included leptomeningeal enhancement (61%), pachymeningeal (23%), intramedullary enhancing lesions (38%) and bony involvement (15%). The cervical segment was most frequently involved followed by the thoracic segment. Involvement was often long segment (4.2 spinal segments) with proclivity for the dorsal cord. Mean follow-up was 23.2 months. A complete or near-complete radiological response occurred in 66% while partial response was seen in 25% patients. Four patients had isolated central nervous system involvement including one with isolated spinal cord involvement. On diffusion-weighted imaging, the apparent diffusion coefficient of intramedullary lesions was increased compared to normal-appearing cord on baseline and subsequent follow-up scans. CONCLUSIONS Spinal sarcoidosis was previously considered uncommon but is being increasingly recognized with widespread use of magnetic resonance imaging. Proclivity for dorsal surface involvement is characteristic, although not necessarily pathognomonic. Also, quantitative diffusion studies may serve as a biomarker for the disease activity and parenchymal injury.

AJNR Am J Neuroradiol 2018; 39:2045-2050. [PMID: 30237298 DOI: 10.3174/ajnr.a5783] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2018] [Accepted: 06/18/2018] [Indexed: 12/25/2022]
Abstract
We describe the prevalence and potential significance of deep medullary vein engorgement on SWI in patients with neurosarcoidosis, a finding that has not been described previously. Engorgement was evaluated for possible associations with meningeal or perivascular disease, intracranial hemorrhage, and venous thrombosis, as well as with modified Rankin Scale scores at the time of MR imaging and at follow-up. Deep medullary vein engorgement was seen in 7 of 21 patients and was more common in men. Patients with venous engorgement had a significantly increased incidence of microhemorrhages, perivascular disease, and hydrocephalus. There was no association with the degree of leptomeningeal disease, venous dural sinus thrombosis, or modified Rankin Scale scores. In conclusion, deep medullary vein engorgement was common in our patients with neurosarcoidosis. Although its pathophysiology remains uncertain, it could be related to venous or perivenous abnormalities and may represent a useful secondary finding of cerebrovascular disease.
