Radiol Case Rep 2024; 19:2168-2182. [PMID: 38515768 PMCID: PMC10950589 DOI: 10.1016/j.radcr.2024.02.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 02/07/2024] [Accepted: 02/09/2024] [Indexed: 03/23/2024] Open
Abstract
Primary central nervous system post-transplant lymphoproliferative disease (PCNS-PTLD) is a rare subset of post-transplant lymphoproliferative disorder (PTLD) isolated to the CNS without nodal or extra-nodal organ involvement [1,2]. PCNS-PTLD occurs primarily in patients following either solid organ transplants or hematopoietic stem cell transplants and tends to be monomorphic DLBCL. The development of PCNS-PTLD is commonly associated with EBV infection [3]. Many intracranial pathologies can resemble the imaging appearance of PCNS-PTLD, including primary CNS lymphoma, glial tumors, metastatic disease, and intracranial abscesses. The purpose of this systematic review is to identify the most common imaging characteristics of PCNS-PTLD. Our review included 97 sources that describe the imaging appearance of PCNS-PTLD. Based on our review, PCNS-PTLD lesions are typically multifocal, ring-enhancing and diffusion-restricting. PCNS-PTLD lesions typically demonstrate focal FDG avidity. Despite advancement in medical imaging, PCNS-PTLD remains a diagnostic challenge due to its rare incidence. Limited data is available on advanced imaging with regards to PTLD, but techniques including DCE-MRI and fMRI demonstrate promising results that may help further delineate PCNS-PTLD.

Abstract
Background: Due to the poor prognosis and rising occurrence, there is a crucial need to improve the diagnosis of Primary Central Nervous System Lymphoma (PCNSL), which is a rare type of non-Hodgkin's lymphoma. This study utilized targeted metabolomics of cerebrospinal fluid (CSF) to identify biomarker panels for the improved diagnosis or differential diagnosis of primary central nervous system lymphoma (PCNSL). Methods: In this study, a cohort of 68 individuals, including patients with primary central nervous system lymphoma (PCNSL), non-malignant disease controls, and patients with other brain tumors, was recruited. Their cerebrospinal fluid samples were analyzed using the Ultra-high performance liquid chromatography - tandem mass spectrometer (UHPLC-MS/MS) technique for targeted metabolomics analysis. Multivariate statistical analysis and logistic regression modeling were employed to identify biomarkers for both diagnosis (Dx) and differential diagnosis (Diff) purposes. The Dx and Diff models were further validated using a separate cohort of 34 subjects through logistic regression modeling. Results: A targeted analysis of 45 metabolites was conducted using UHPLC-MS/MS on cerebrospinal fluid (CSF) samples from a cohort of 68 individuals, including PCNSL patients, non-malignant disease controls, and patients with other brain tumors. Five metabolic features were identified as biomarkers for PCNSL diagnosis, while nine metabolic features were found to be biomarkers for differential diagnosis. Logistic regression modeling was employed to validate the Dx and Diff models using an independent cohort of 34 subjects. The logistic model demonstrated excellent performance, with an AUC of 0.83 for PCNSL vs. non-malignant disease controls and 0.86 for PCNSL vs. other brain tumor patients. Conclusion: Our study has successfully developed two logistic regression models utilizing metabolic markers in cerebrospinal fluid (CSF) for the diagnosis and differential diagnosis of PCNSL. These models provide valuable insights and hold promise for the future development of a non-invasive and reliable diagnostic tool for PCNSL.

Abstract
Primary central nervous system lymphomas (PCNSLs) are extranodal variant forms of non-Hodgkin lymphoma arising within the brain parenchyma, leptomeninges, or spinal cord. PCNSL can present with varied neurological symptoms and imaging findings, making diagnosis without biopsy difficult. PCNSLs are highly aggressive, causing rapid deterioration, but are responsive to chemotherapy and radiotherapy making early diagnosis important. Crossed cerebellar diaschisis (CCD) is mostly seen with cerebral cortex vascular insults and is rarely reported with thalamic lesions and even rarer with thalamic lymphoma. However, CCD has also been described in other brain tumors (including primary glioma), chronic subdural hematoma, congenital insults, intracranial infections, and various dementia subtypes. We present a rare case of thalamic lymphoma evaluated with positron emission tomography/computed tomography that showed hypermetabolism of thalamus and associated hypometabolism in ipsilateral cerebral cortex and contralateral cerebellum representing CCD.

Abstract
Objective Primary central nervous system lymphomas (PCNS) are relatively rare tumors, accounting for about 4% of all brain tumors. On neuroimaging, they are characterized by a low MR signal in T1, isointense in T2, bright uniform contrast enhancement, and diffusion restriction. The aim of this study is to note the lack of effectiveness of the MR/CT perfusion technique in complex multiparametric imaging in the differential diagnosis of primary lymphomas of the central nervous system in comparison with highly malignant gliomas and brain metastases. Materials and Methods This prospective study included 80 patients with CNS tumors examined/operated at the Federal Center for Neurosurgery (Tyumen, Russia) from 2018 to 2021. The patients were divided into 4 groups: group 1 consisted of 33 cases with primary CNS lymphomas (10 cases with atypical manifestations according to perfusion parameters and 23 cases of classic CNS lymphomas), group 2 with anaplastic astrocytomas—14 cases, group 3—23 cases with glioblastomas and group 4—10 cases with solitary metastatic lesions. The study was carried out on a General Electric Discovery W750 3T magnetic resonance tomograph, a Canon Aquilion One multispiral X-ray computed tomograph (Gadovist 7.5 ml, Yomeron 400 mg−50 ml). Additionally, immunohistochemical analysis was carried out with the following markers: CD3, CD20, CD34, Ki-67, VEGF. Results It has been established that MR/CT perfusion is not a highly sensitive method for visualizing primary CNS lymphomas, as previously thought, but at the same time, the method has a number of undeniable advantages that make it indispensable in the algorithm of a complex multiparametric diagnostic approach for this type of tumor. Nevertheless, PLCNS is characterized by an atypical manifestation, which is an exception to the rule. Conclusions The possibilities of neuroimaging of primary lymphomas, even with the use of improved techniques for collecting MR/CT data, are limited and do not always allow reliable differentiation from other neoplasms.

Abstract
Lymphoproliferative disorders (LPD) are conditions characterized by the uncontrolled proliferation of B or T-cell lines. They encompass a wide spectrum of abnormalities, which may be broadly classified as reactive processes or malignant diseases, such as lymphoma, based on their cellular clonality and clinical behavior. While some of these disorders are rare, they may be encountered sporadically in clinical practice, causing diagnostic dilemmas owing to overlap in their clinical and imaging features with more common disorders. The updated 4th edition WHO classification of lymphoid neoplasms was released in 2016 to incorporate the rapid clinical, pathological, molecular biology and cytogenetic advances of some of these disorders. Despite these updates, very little information is presented in the literature from the radiology perspective. The aim of this article is to familiarize radiologists and other physicians with certain rare variants of B-cell lymphoproliferative disorders with a focus on imaging features of these disorders, as well as to provide an overview of some important updates contained within the new WHO classification of lymphoid neoplasms.

Abstract
Terson Syndrome (TS) describes the presence of intraocular hemorrhage in patients with intracranial hemorrhage, typically subarachnoid hemorrhage. Despite TS being a well-defined and frequently occurring phenomenon, its pathophysiology remains controversial. This review will present the current understanding of TS, with view to describing a contemporary and more plausible pathomechanism of TS, given recent advances in ophthalmic science and neurobiology. Previously proposed theories include a sudden rise in intracranial pressure (ICP) transmitted to the optic nerve sheath leading to rupture of retinal vessels; or intracranial blood extending to the orbit via the optic nerve sheath. The origin of blood in TS is uncertain, but retinal vessels appear to be an unlikely source. In addition, an anatomical pathway for blood to enter the eye from the intracranial space remains poorly defined. An ocular glymphatic system has recently been described, drainage of which from the globe into intracranial glymphatics is reliant on the pressure gradient between intraocular pressure and intracranial pressure. The glymphatic pathway is the only extravascular anatomical conduit between the subarachnoid space and the retina. We propose that subarachnoid blood in skull base cisterns near the optic nerve is the substrate of blood in TS. Raised ICP causes it to be refluxed through glymphatic channels into the globe, resulting in intraocular hemorrhage. We herewith present glymphatic reflux as an alternative theory to explain the phenomenon of Terson Syndrome.

Abstract
This review addresses the challenges of primary central nervous system (CNS) lymphoma diagnosis, assessment of treatment response, and detection of recurrence. Primary CNS lymphoma is a rare form of extra-nodal non-Hodgkin lymphoma that can involve brain, spinal cord, leptomeninges, and eyes. Primary CNS lymphoma lesions are most commonly confined to the white matter or deep cerebral structures such as basal ganglia and deep periventricular regions. Contrast-enhanced magnetic resonance imaging (MRI) is the standard diagnostic modality employed by neuro-oncologists. MRI often shows common morphological features such as a single or multiple uniformly well-enhancing lesions without necrosis but with moderate surrounding edema. Other brain tumors or inflammatory processes can show similar radiological patterns, making differential diagnosis difficult. [18F]-fluorodeoxyglucose (FDG) positron emission tomography (PET) has selected utility in cerebral lymphoma, especially in diagnosis. Primary CNS lymphoma can sometimes present with atypical findings on MRI and FDG PET, such as disseminated disease, non-enhancing or ring-like enhancing lesions. The complementary strengths of PET and MRI have led to the development of combined PET-MR systems, which in some cases may improve lesion characterization and detection. By highlighting active developments in this field, including advanced MRI sequences, novel radiotracers, and potential imaging biomarkers, we aim to spur interest in sophisticated imaging approaches.

Abstract
Primary central nervous system lymphoma (PCNSL) is an aggressive cancer typically confined to the brain, eyes, leptomeninges and spinal cord, without evidence of systemic involvement. PCNSL remains a challenge for scientists and clinicians due to insufficient biological knowledge, a lack of appropriate animal models and validated diagnostic biomarkers. We summarize recent findings on genomic, transcriptomic and epigenetic alterations identified in PCNSL. These findings help to define pathobiology of the disease and delineate defects in B cell differentiation. Evidence from genomic and transcriptomic studies helps to separate PCNSL from other hematological malignancies, improves diagnostics and reveals new therapeutic targets for treatment. Discovery of the CNS lymphatic system may be instrumental in better understanding the origin of the disease. We critically assess the attempts to model PCNSL in rodents, and conclude that there is a lack of a genetic/transgenic model that adequately mimics pathogenesis of the disease. Contribution of the tumor microenvironment in tumorigenesis and aggressiveness of PCNSL remains understudied. Assessing heterogeneity of immune infiltrates, cytokine profiling and molecular markers, may improve diagnostics and put forward new therapeutic strategies.

Abstract
BACKGROUND Primary central nervous system lymphoma (PCNSL) is a rare manifestation of aggressive extranodal non-Hodgkin lymphoma. In patients with deep-seated lesions, stereotactic brain biopsy (SBB) is an accepted diagnostic procedure to obtain histopathologic confirmation. OBJECTIVE The aim of this study was to assess the feasibility, diagnostic yield, safety, and complications of stereotactic procedures in midline and deep-seated PCNSLs. METHODS Patients selected had received a histopathologic diagnosis of PCNSL localized in deep-seated midline structures, obtained by SBB. The intraoperative frozen section was executed as an integral part of the procedure. Computed tomography scan was performed after surgery. RESULTS A total of 476 SBBs were performed between January 2000 and December 2019 . Of these SBBs, 91 deep-seated lesions had a histologic diagnosis of PCNSL. A significant increase of the incidence of PCNSL compared with all other diseases was observed (P < 0.0001). Eight patients (8.7%) showed a symptomatic hemorrhage, 4 of whom required craniotomy. There were 4 deaths and 2 cases of permanent morbidity. The hemorrhage risk in the PCNSL group was statistically significant (P = 0.0003) compared with other histotypes. CONCLUSIONS In suspected cases of PCNSL, a histopathologic diagnosis is necessary to distinguish it from glioblastoma or other, nonmalignant conditions. Deep-seated PCNSLs present a higher risk of biopsy-related morbidity and mortality. Intraoperative frozen section increases the diagnostic yield and reduces the number of sampling procedures. Postoperative computed tomography seems to be warranted in patients with suspected PCNSL.

Abstract
Primary central nervous system (CNS) marginal zone B-cell lymphoma (MZBCL) arising from the dural meninges is a rare but indolent disease. This malignancy can present in various ways, hence making it difficult to diagnose. Biopsy results dictate an appropriate treatment plan, which commonly consists of a combination of surgical resection, whole brain radiotherapy and systemic therapy.

Lymphomas are malignant lymphoid tumours arising from lymphocytic cells. They usually develop in the lymphoid tissues and can spread to other organs; however, primary extra-nodal locations such as the spinal epidural space are less common. The authors report the case of a primary diffuse large B-cell lymphoma of the thoracic spine in a 65-year-old man, who presented to the emergency department with signs of upper motor neuron lesion. The patient underwent surgery in order to decompress the spinal cord. The treatment was concluded with six cycles of chemotherapy with methotrexate, rituximab, cyclophosphamide, vincristine and prednisone followed by radiotherapy. At the 24-month follow-up, no signs of epidural lesion or bone contrast enhancement were observed in thoracic spine MRI. Surgical decompression is recommended in patients with signs of spinal cord injury in order to prevent irreversible neurological damage and is related to high rates of disease-free survival.

Abstract
Background This study aimed to compare the magnetic resonance imaging (MRI) findings of primary diffuse large B-cell lymphoma (DLBCL) of the central nervous system (CNS) with delayed contrast enhancement and histological microvessel density (MVD). T1-weighted and T2-weighted contrast-enhanced and non-enhanced brain imaging were used. CNS lymphoma tissue was evaluated using primary antibodies to endothelial cells and smooth muscle cells, and histochemical staining for reticulin fibers and basement membrane, which allowed quantification of the MVD. Material/Methods Twenty-one patients with histologically confirmed primary DLBCL of the CNS underwent pre-contrast-enhanced and postcontrast-enhanced MRI. Histology of the CNS lymphoma tissue included immunohistochemical staining with antibodies to CD34 for vascular endothelial cells and alpha smooth muscle actin (ASMA) for vascular smooth muscle cells, and histochemical staining included periodic acid-Schiff (PAS) and silver staining for reticulin fibers to evaluate microvessel density (MVD). Results In primary DLBCL of the CNS, a positive correlation was found between the degree of necrosis and the size of the lymphoma (r=0.546, P=0.01). Delayed imaging enhancement was significantly correlated with the number of mature vessels, MVD, basement membrane, and reticulin fibers (r=0.593, 0.466, 0.446 and 0.497, respectively). Standardized β regression coefficient analysis showed that the MVD, PAS-positive structures, the number of mature vessels, and reticulin fibers, were significantly associated with delayed enhancement on MRI (β values, 0.425, 0.409, 0.295, and 0.188, respectively). Conclusions In primary DLBCL of the CNS, delayed imaging enhancement on MRI may be due to reduced neovascularization and vascular infiltration by lymphoma cells.

Abstract
Psychotic manifestations of brain tumours are rare but described in the literature mostly along with other neurological deficits. Memory loss, difficulty in attention and concentration, depression, anxiety, and mood symptoms are commonly described in brain tumours. A schizophrenia-like picture without a deficit in motor or sensory function may land the clinician into a diagnostic dilemma. Primary central nervous system lymphoma (PCNSL) is a highly malignant disease with high mortality and needs immediate attention. Our case which had a unique recurrence in the postoperative period with psychotic symptoms can be an eye-opener to be more vigilant about underlying clinical extension.

Abstract
Background Because of the low incidence of primary central nervous system lymphoma (PCNSL) in non-HIV individuals and because of the lack of specific clinical manifestations and auxiliary examinations, the disease is easily missed or misdiagnosed. Objective To analyze the imaging features of PCNSL in non-HIV patients. Methods This was a retrospective study of patients with PCNSL treated between January 2001 and December 2011 at the Naval General Hospital (Beijing, China). All included patients were pathologically diagnosed with PCNSL. Specimens were obtained by stereotactic biopsy and diagnosed by pathological examination. Serological panel had to be negative for HIV. Results Out of the 118 patients, 73 (61.9%) were male and 45 (38.1%) were female. Median age was 54 (range 11–83) years. All patients had B cell lymphoma. The lesions showed slightly hyperintense shadows on computed tomography (CT) images, and mostly hyperintense T1 and iso- or hyperintense T2 signals on magnetic resonance imaging (MRI). Most lesions showed patchy enhancement after enhanced scanning, and some had the characteristic “butterfly sign” on enhanced MRI. The magnetic resonance spectroscopy of PCNSL manifested as increased Cho peak, moderately decreased NAA peak, and slightly decreased Cr peak. Positron emission computed tomography indicated high metabolism of 18F-FDG in PCNSL lesions. Conclusion MRI is important in the diagnosis of PCNSL. Understanding the imaging features of PCNSL will help improve its diagnosis in clinics.

Abstract
Background Primary central nervous system lymphoma is a rare, malignant non-Hodgkin lymphoma that can arise in the brain, spinal cord, eye, leptomeninges, or cranial nerves. Primary central nervous system lymphoma is rare, accounting for 2–6% of all primary brain neoplasms and 1–2% of all non-Hodgkin lymphomas, and it usually presents as a solitary lesion. Cerebellar involvement is present in only 9% of cases. We present an unusual case of primary central nervous system lymphoma presenting as multiple lesions in the cerebellum in an immunocompetent host. Case presentation A 71-year-old Caucasian man presented to our hospital with acute onset of dizziness, nausea, vomiting, and gait imbalance. Contrast-enhanced computed tomography revealed three intensely enhancing masses in the right cerebellar hemisphere. Whole-body positron emission tomography and computed tomography failed to demonstrate a primary tumor of origin outside the central nervous system. The patient underwent right suboccipital craniotomy with partial resection of the visible tumor from the right cerebellum. Histopathology revealed diffuse large B-cell lymphoma, non-germinal center type. Conclusions Primary central nervous system lymphoma is rare, even more so in the cerebellum. However, the overall incidence of primary central nervous system lymphoma is rising in both immunocompromised and immunocompetent patients. The highly aggressive nature of primary central nervous system lymphoma necessitates timely diagnosis and intervention. In this report, we review the available literature for a better understanding of the pathophysiology and management of primary central nervous system lymphoma. To the best of our knowledge, this is the first reported case of a patient with primary central nervous system lymphoma presenting with multiple masses in the cerebellum.

Abstract
The epidemiology of spinal cord disease in human immunodeficiency virus (HIV) infection is largely unknown due to a paucity of data since combination antiretroviral therapy (cART). HIV mediates spinal cord injury indirectly, by immune modulation, degeneration, or associated infections and neoplasms. The pathologies vary and range from cytotoxic necrosis to demyelination and vasculitis. Control of HIV determines the differential for all neurologic presentations in infected individuals. Primary HIV-associated acute transverse myelitis, an acute inflammatory condition with pathologic similarities to HIV encephalitis, arises in early infection and at seroconversion. In contrast, HIV vacuolar myelopathy and opportunistic infections predominate in uncontrolled disease. There is systemic immune dysregulation as early as primary infection due to initial depletion of gut-associated lymphoid tissue CD4 cells and allowance of microbial translocation across the gut that never fully recovers throughout the course of HIV infection, regardless of how well controlled. The subsequent proinflammatory state may contribute to spinal cord diseases observed even after cART initiation. This chapter will highlight an array of spinal cord pathologies classified by stage of HIV infection and immune status.

Abstract
There are many infectious and inflammatory processes affecting the central nervous system that can simulate other neurosurgical pathologies (e.g. tumor) and may precipitate a brain biopsy for definitive diagnosis if not suspected a priori. The challenge for the healthcare team is to recognize imaging features that support a nonsurgical pathology to avoid unnecessary interventions. This review aims to give a general overview of some common inflammatory and infectious entities that affect the central nervous system, with illustrative examples and highlighting important pearls and pitfalls.

Abstract
Primary central nervous system (CNS) lymphomas are uncommon and their management differs significantly from that of other malignant tumors involving the CNS. This article explains how the imaging findings often suggest the diagnosis early. The typical findings in immunocompetent patients consist of a supratentorial intraaxial mass that enhances homogeneously. Other findings to evaluate include multifocality and incomplete ring enhancement. The differential diagnosis of primary CNS lymphomas should consider mainly other malignant tumors of the CNS such as glioblastomas or metastases. Primary CNS lymphomas tend to have less edema and less mass effect; they also tend to spare the adjacent cortex. Necrosis, hemorrhage, and calcification are uncommon in primary CNS lymphomas. Although the findings in morphologic sequences are characteristic, they are not completely specific and atypical types are sometimes encountered. Advanced imaging techniques such as diffusion or especially perfusion provide qualitative and quantitative data that play an important role in differentiating primary CNS lymphomas from other brain tumors.

Abstract
Background: The most common lymphoid malignancy in adults is diffuse large B-cell lymphoma (DLBCL). The median age of occurrence of DLBCL is between 6th and 7th decade of life, although some other types of aggressive non-Hodgkin’s lymphomas (NHL) are present in younger age. Primary central nervous system lymphoma (PCNSL) is an uncommon type of extranodal NHL, which is either more prevalent or is diagnosed more often than before. Case Description: A 22-year-old man with ventriculoperitoneal shunt (VPS) performed at another center was referred with manifestations of shunt malfunction, unusual behavior, dysphasia, and hallucination. The shunt malfunction was handled appropriately several times and exploration of the enhancing cystic temporal lesion confirmed the diagnosis of DLBCL. Conclusion: In this communication, we intend to highlight the issue that hydrocephalus refractory to several interventions can be the sole manifestation of PCNSL and needs special clinical considerations.

Abstract
The spectrum of pituitary stalk (PS) pathology is vast, presenting a diagnostic challenge. Published large series of PS lesions demonstrate neoplastic conditions are most frequent, followed by inflammatory, infectious and congenital diseases. Inflammatory pathologies however, account for the majority of PS lesions in published small case series and case reports. Physicians must be familiar with the major differential diagnoses and necessary investigations. A comprehensive history and thorough clinical examination is critical. Although magnetic resonance imaging of the PS in disease is nonspecific, associated intracranial features may narrow the differential diagnosis. Initial investigations include basic pathology and computer tomography imaging of the neck, chest, abdomen and pelvis. Further investigations should be guided by the clinical context. PS biopsy should be considered when a diagnosis is regarded essential in centres where an experienced neurosurgeon is available. Treatment is dependent on the underlying disease process and may necessitate pituitary hormone replacement.

Abstract
Lymphoma is one of the most common neoplasms in the dog. Despite its prevalence and the increasing use of advanced diagnostic imaging in veterinary patients only few reports of magnetic resonance imaging (MRI) findings in spinal lymphoma have been published to date. The purpose of this retrospective case series study was to describe the MRI findings in dogs with confirmed lymphoma affecting the spine and/or paraspinal soft tissues. Medical records were searched for patients that had MRI of the spine and a diagnosis of lymphoma during the period of 2005-2015. Data recorded from retrieved MRI studies were presence of focal or multifocal disease, structures involved, and signal characteristics on T2-W, short tau inversion recovery (STIR), and T1-W sequences prior to and following intravenous contrast medium administration. Six dogs met the inclusion criteria. Common findings included multifocal disease (4/6), vertebral involvement (5/6), spinal cord compression (4/6), and involvement of more than one spinal compartment (medullary cavity, vertebral canal, paraspinal soft tissues) (6/6). Vertebral changes were confined to the medullary cavity without evidence of cortical osteolysis. There was questionable involvement of the spinal cord in one case. All spinal and paraspinal lesions identified were T2-W isointense to hyperintense, STIR hyperintense, T1-W hypointense to isointense, and showed variable moderate to strong contrast enhancement. Additional lesions identified were enlarged intraabdominal lymph nodes, hepatomegaly, splenomegaly, and a splenic nodule. The STIR and T1-W postcontrast sequences were subjectively the most useful in identification of the spinal and paraspinal lesions.

Abstract
Background. Primary spinal dural lymphomas (PSDL) are tumors with characteristic histopathology of a lymphoma, which are completely in the spinal epidural space without any other systemic involvement. Extranodal primary lymphoma involving nervous system prefers thalamus/basal ganglia, periventricular region, cerebellum, eyes, meninges/dura, and cranial nerves or spinal cord. Rare spinal localization with acute spinal cord compression is worth attention. Case Presentation. A 48-year-old male presented with a several-month-long history of upper back pain. Lately, he had numbness and weakness at both lower extremities and was unable to walk for one week. A spinal MRI showed a thoracic lesion with cord compression at T2-T4 levels. The patient underwent surgical decompression, with his final histopathology showing diffuse large B-cell lymphoma. Systemic work-up was negative for nodal disease. Following surgery, he received radiotherapy combined with chemotherapy. He experienced a good outcome after four years. Conclusion. The upper thoracic cord is a rare location for primary spinal lesions/metastases, both of which prefer the lower thoracic and upper lumbar regions. In cases of progressive paraparesis, there should be immediate surgical intervention in the case of denovo disease, followed by combined radiotherapy and chemotherapy procedures.

Abstract
OBJECTIVE Define the neurocognitive features of primary central nervous system lymphoma (PCNSL) presenting with dementia, and compare with other causes of rapidly progressive dementia (RPD). BACKGROUND PCNSL can present as an RPD. Differentiating PCNSL from other RPDs is critical because lymphomatous dementia may be reversible, and untreated PCNSL is fatal. METHODS We performed a meta-analysis of case reports of dementia from PCNSL (between 1950 and 2013); 20 patients (14 with lymphomatosis cerebri) met our criteria. We compared these patients to a case series of patients with RPD from Creutzfeldt-Jakob disease and other non-PCNSL etiologies (Sala et al, 2012. Alzheimer Dis Assoc Disord. 26:267-271). RESULTS Median age was 66 years (range 41 to 81); 70% were men. Time from symptom onset to evaluation was <6 months in 65%. No patients had seizures; 5% had headaches; 45% had non-aphasic speech difficulty. There was significantly more memory impairment in patients with PCNSL than other RPDs and significantly less myoclonus and parkinsonism. Behavioral changes and cerebellar signs were not significantly different. Significantly more patients with PCNSL than other RPDs had white matter changes; significantly fewer had atrophy. Elevated CSF protein and pleocytosis were more frequent in PCNSL; patients with other RPDs tended to have normal CSF±14-3-3 protein. CONCLUSIONS Unlike patients with RPD from other causes, those with PCNSL commonly present with impaired memory, apathy, and abnormal speech and gait, without headache, seizure, or myoclonus. White matter changes and CSF abnormalities predominate. Improved clinical awareness of PCNSL can prompt earlier diagnosis and treatment.

Abstract
Primary central nervous system lymphoma (PCNSL) is a rare subtype of extranodal non-Hodgkin lymphoma, which is limited to the central nervous system. Few studies are available reporting psychiatric symptoms as the initial and dominant presentation of PCNSL. The current study reports the case of a PCNSL patient with a history of major depressive disorder and coexisting rheumatoid arthritis (treated with methotrexate), who initially presented with recurrent depressive disorder that showed no response to antidepressant drug therapy. Magnetic resonance imaging revealed multiple mass lesions in the brain, and pathological examination of the biopsy confirmed the diagnosis of diffuse large B cell lymphoma of the central nervous system. The present case demonstrated that PCNSL may affect mood in the early stages of the disease and thus, clinicians must be aware of this manifestation in patients with depressive disorder co-existing with immunosuppressive conditions, as early detection and appropriate treatment are important prognostic factors for PCNSL.

Abstract
We aimed to characterize specific MRI findings seen in immune competent patients with intracranial primary CNS lymphoma (PCNSL) and to determine their value in the management of such patients. Pre-treatment MRI examinations of 21 immunocompetent patients with biopsy-proven PCNSL were retrospectively evaluated. T1 and T2 signal characteristics as well as contrast enhancement features are described in all patients. Diffusion, perfusion and proton-MR-spectroscopy features are described in a subset of these patients. In the proper clinical and radiologic setting, suggesting the diagnosis of PCNSL can help institute proper treatment in a timely fashion and avoid unnecessary attempts at surgical resection and the associated morbidity.

Abstract
The diagnosis of primary central nervous system lymphoma (PCNSL) can be suggested by magnetic resonance imaging (MRI). Cerebral PCNSL in immunocompetent patients generally shows marked homogeneous contrast enhancement in MRI. However, confirmation of it requires demonstration of lymphoma cells in stereotactic biopsy of the lesion or in cerebrospinal fluid. In the present case, with radiologic diagnosis of glioma, complete resection of the lesion by micro-neurosurgical technique was performed. The tumor tissue was examined by squash smear, frozen section and paraffin sections. Cytologic appreciation of tumor cells as lymphoid origin in squash smears negated the other possibilities. The immunocytochemistry on squash smear and immunohistochemistry on paraffin sections confirmed the diagnosis of diffuse large B cell lymphoma of non-germinal center B cell phenotype.

Abstract
BACKGROUND The authors present a retrospective analysis of 45 patients who underwent treatment of CNS lymphoma (both primary and secondary) at a single institution between 2005 and 2012. METHODS This study involves 21 female and 24 male patients with a mean age of 59.2 years. All medical records and pathology reports were reviewed for each patient. Univariate and multivariate analyses of overall survival were performed. RESULTS Presentation with altered mental status was a significant risk factor for worse overall survival. An HIV infection, deep lesion location, and age over 60 did not impact survival. A survival benefit was demonstrated with the use of systemic therapy, specifically rituximab, and radiation. The CNS Lymphoma Score was derived from this cohort, which proved a powerful predictive tool for overall survival. The surgical complication rate in this series was 17.8 %. CONCLUSIONS This study highlights the prognostic importance of presenting mental status on outcomes in CNS lymphoma and demonstrates a summative benefit of rituximab and whole brain radiation therapy. Considering these factors together provides an easily applicable and meaningful stratification for this patient population. The surgical complication rate in this patient population is not negligible. The high percentage of wound-related surgical complications suggests the need for a waiting period between surgery and initiation of chemotherapy to allow for wound healing.

Abstract
The typical neuroimaging features of primary central nervous system lymphoma (PCNSL) have been described as single or multiple intra-axial, homogenous, contrast-enhancing lesions with marked perilesional edema and restricted diffusion, usually contacting the cerebrospinal fluid surface. Necrosis, peripheral enhancement, hemorrhages, and calcifications are unusual. Recently, some of our patients with PCNSL have had atypical neuroimaging features even before treatment. In this article, we review the neuroimaging characteristics of PCNSL in immunocompetent patients and analyzed how imaging findings over the last 10 years differ from those from more than 10 years ago. Neuroimaging findings suggest that PCNSL is a disease that affects the entire brain. Although some imaging findings are characteristic of PCNSL, the frequency of atypical findings on conventional neuroimaging is increasing. Atypical neuroimaging findings do not rule out PCNSL, even in immunocompetent patients.

Abstract
Central nervous system (CNS) lymphoma can present a diagnostic challenge. Currently, there is no consensus regarding what presurgical evaluation is warranted or how to proceed when lesions are not surgically accessible. We conducted a review of the literature on CNS lymphoma diagnosis (1966 to October 2011) to determine whether a common diagnostic algorithm can be generated. We extracted data regarding the usefulness of brain and body imaging, serum and cerebrospinal fluid (CSF) studies, ophthalmologic examination, and tissue biopsy in the diagnosis of CNS lymphoma. Contrast enhancement on imaging is highly sensitive at the time of diagnosis: 98.9% in immunocompetent lymphoma and 96.1% in human immunodeficiency virus-related CNS lymphoma. The sensitivity of CSF cytology is low (2%-32%) but increases when combined with flow cytometry. Cerebrospinal fluid lactate dehydrogenase isozyme 5, β2-microglobulin, and immunoglobulin heavy chain rearrangement studies have improved sensitivity over CSF cytology (58%-85%) but have only moderate specificity (85%). New techniques of proteomics and microRNA analysis have more than 95% specificity in the diagnosis of CNS lymphoma. Positive CSF cytology, vitreous biopsy, or brain/leptomeningeal biopsy remain the current standard for diagnosis. A combined stepwise systematic approach outlined here may facilitate an expeditious, comprehensive presurgical evaluation for cases of suspected CNS lymphoma.

Abstract
The spinal cord is an extremely rare site for primary central nervous system (CNS) lymphoma (< 1%). Very few cases of primary cauda equina (including conus) lymphoma were previously reported. We report such a case, and with literature review, discuss their clinical features, operative and histopathological findings. Although rare, with an increasing incidence of CNS lymphoma, they should be considered in the differential diagnosis of intradural lesions. Furthermore, with intraoperative smear to establish diagnosis, extensive surgery can be avoided. The controversial role of glucocorticoids in the management of these patients is also discussed.

Abstract
The presence of a primary central nervous system (CNS) neoplasm within the corpus callosum generally portends a grave prognosis. Common pathologies encountered include glioblastomas and primary CNS lymphomas. In contrast, World Health Organization grade II oligodendroglial tumors demonstrating loss of heterozygosity at 1p and 19q are generally less aggressive, often responding favorably to chemotherapy. The authors present a case of a primary brain tumor isolated to the corpus callosum diagnosed as a grade II oligodendroglioma. A 52-year-old woman presented with new-onset generalized seizure. Magnetic resonance imaging (MRI) revealed a non-contrast-enhancing lesion with associated edema and regional mass effect. The patient underwent a craniotomy and subtotal resection of the lesion using an endoscopic port. Pathological examination revealed a grade II oligodendroglioma. Molecular analysis identified 1p and 19q deletion as well as MGMT promoter methylation. The patient subsequently underwent adjuvant radiation therapy with an excellent response. We present, to our knowledge, the first report of a grade II oligodendroglioma isolated within the corpus callosum with the characteristic molecular features of this tumor type. Histopathologic diagnosis is essential to appropriately guide therapy of callosal tumors.

Abstract
Intramedullary primary central nervous system lymphoma (PCNSL) is a rare central nervous system (CNS) malignancy affecting mostly the brain, but it may also involve the leptomeninges, eyes, and spinal cord. A 71-year-old woman presented with back pain and progressive unilateral lower extremity weakness owing to an intramedullary primary histiocytic sarcoma of the spine, a rare PCNSL subtype. To the authors' knowledge, this is the first case of an intramedullary PCNSL caused by histiocytic sarcoma.

Abstract
CNS lymphoma consists of 2 major subtypes: secondary CNS involvement by systemic lymphoma and PCNSL. Contrast-enhanced MR imaging is the method of choice for detecting CNS lymphoma. In leptomeningeal CNS lymphoma, representing two-thirds of secondary CNS lymphomas, imaging typically shows leptomeningeal, subependymal, dural, or cranial nerve enhancement. Single or multiple periventricular and/or superficial contrast-enhancing lesions are characteristic of parenchymal CNS lymphoma, representing one-third of secondary CNS lymphomas and almost 100% of PCNSLs. New CT and MR imaging techniques and metabolic imaging have demonstrated characteristic findings in CNS lymphoma, aiding in its differentiation from other CNS lesions. Advanced imaging techniques may, in the future, substantially improve the diagnostic accuracy of imaging, ultimately facilitating a noninvasive method of diagnosis. Furthermore, these imaging techniques may play a pivotal role in planning targeted therapies, prognostication, and monitoring treatment response.

Abstract
STUDY DESIGN A case report with a review of the literature. OBJECTIVE To describe an unusual case of primary lymphoma of the cauda equina and provide a review of the literature of this condition. SUMMARY OF BACKGROUND DATA Primary lymphoma of the cauda equina is extremely rare, and has been reported in 8 cases previously. This report is the first to describe a case of primary nasal type NK/T-cell lymphoma of the cauda equina. METHODS We report the case of a 67-year-old man presenting the symptoms of cauda equina syndrome caused by primary lymphoma of the cauda equina. RESULTS After laminectomy and removal of the tumor, the patient recovered from the symptoms of cauda equina syndrome except for bladder and bowel dysfunction. Further investigations including immunohistochemical stains made a diagnosis of primary nasal type NK/T-cell lymphoma of the cauda equina, and the patient received radiotherapy to the lumbosacral area. Brain metastasis was detected 8 months after surgery, and the patient died 14 months after his initial clinical presentation despite additional treatments including whole-brain radiotherapy and oral chemotherapy. CONCLUSION Although primary lymphoma of the cauda equina is extremely rare, the prognosis of this condition is thought to be poor. Early definitive diagnosis with examination of the cerebrospinal fluid followed by combined treatment with radiotherapy and high-dose methotrexate should be considered.

Abstract
Posttransplant lymphoproliferative disorder (PTLD) is an uncommon neoplastic complication of kidney transplantation, affecting about 1% of recipients. It is generally associated with Epstein-Barr virus (EBV) infection of B-lineage lymphocytes. Central nervous system (CNS) involvement is rare. There is little clinical experience with treatment of CNS PTLD due to the relative rarity of the disease other than reduction or withdrawal of immunosuppression, but it is usually fatal. We describe six patients with renal allografts and histologically proven isolated CNS PTLD. Tissue analysis from the biopsy specimens was positive for EBV material in five of the six patients. All six patients were treated with high-dose intravenous methotrexate (HD IV MTX). Methotrexate was initiated at 8 g/m2, with later adjustments for creatinine clearance. With MTX therapy, four patients have had a sustained complete response, and two had progressive disease and were referred for radiation therapy. This finding suggests a subgroup of patients may benefit from MTX but our case series is inadequate to describe overall efficacy. No unexpected toxicities were encountered in 37 courses of treatment. HD IV MTX chemotherapy should be considered as an alternative for treatment of CNS PTLD.

Abstract
BACKGROUND AND PURPOSE Studying imaging findings of non-acquired immunodeficiency syndrome (AIDS) primary central nervous system lymphoma (PCNSL), we hypothesized that the imaging presentation has changed with the increasing incidence of PCNSL and is related to clinical factors (eg, time to diagnosis and the patient's being diagnosed alive or at postmortem examination). MATERIALS AND METHODS Chart and histologic reviews of patients recorded as having PCNSL during 1989-2003 in the Norwegian Cancer Registry identified 98 patients with non-AIDS PCNSL; 75 had available imaging. CT and MR images from the first diagnostic work-up after onset of symptoms but before histologic diagnosis were reviewed. RESULTS CT and/or MR imaging in the 75 patients revealed no lesion in 10 (13%), a single focal lesion in 34 (45%), multiple focal lesions in 26 (35%), and disseminated lesions in 5 (7%) patients. All together, we identified 103 focal lesions (single/multiple): 63% in white matter, 56% abutting the ventricular surface, and 43% in the frontal lobes); 100% (102/102 lesions evaluated with contrast) showed contrast enhancement. The median time from imaging to diagnosis for patients with no, single, multiple, or disseminated lesions was 32, 3, 5, and 3 weeks, respectively (P = .01). Patients with no or disseminated lesions were more often diagnosed at postmortem examination (P = .06). Imaging findings were practically unchanged during the consecutive 5-year periods. CONCLUSIONS White matter periventricular contrast-enhancing single or multiple focal lesions were typical of non-AIDS PCNSL. No or disseminated lesions heightened the risk of delayed or postmortem diagnosis. Although the incidence of non-AIDS PCNSL has increased, its presentation at imaging remains unchanged.
