Primary Cauda Equina Lymphoma Mimicking Meningioma. J Clin Med 2024; 13:4959. [PMID: 39201102 PMCID: PMC11355680 DOI: 10.3390/jcm13164959] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2024] [Revised: 08/01/2024] [Accepted: 08/01/2024] [Indexed: 09/02/2024] Open
Abstract
Background: Spinal cord lymphomas represent a minority of extranodal lymphomas and often pose diagnostic challenges by imitating primary spinal tumors or inflammatory/infective lesions. This paper presents a unique case of primary cauda equina lymphoma (PCEL) and conducts a comprehensive review to delineate the clinical and radiological characteristics of this rare entity. Case Report: A 74-year-old male presented with progressive paresthesia, motor weakness, and symptoms indicative of cauda equina syndrome. Neurological examination revealed paraparesis and sphincter dysfunction. Imaging studies initially suggested an intradural meningioma. However, surgical intervention revealed a diffuse large B-cell lymphoma infiltrating the cauda equina. Findings: A systematic review of the pertinent literature identified 18 primary cauda equina lymphoma cases. These cases exhibited diverse clinical presentations, treatments, and outcomes. The mean age at diagnosis was 61.25 years for women and 50 years for men, with an average follow-up of 16.2 months. Notably, 35% of patients were alive at 18 months, highlighting the challenging prognosis associated with PCEL. Discussion: Primary spinal cord lymphomas, especially within the cauda equina, remain rare and diagnostically complex due to their nonspecific clinical manifestations. The review highlights the need to consider spinal cord lymphoma in patients with neurological symptoms, even without a history of systemic lymphoma. Diagnostic Approaches: Magnetic resonance imaging (MRI) serves as the primary diagnostic tool but lacks specificity. Histopathological examination remains the gold standard for definitive diagnosis. The review underscores the importance of timely biopsy in suspected cases to facilitate accurate diagnosis and appropriate management. Management and Prognosis: Current management involves biopsy and chemotherapy; however, optimal treatment strategies remain ambiguous due to the rarity of PCEL. Despite aggressive therapeutic interventions, prognosis remains poor, emphasizing the urgency for enhanced diagnostic and treatment modalities. Conclusions: Primary cauda equina lymphoma poses diagnostic and therapeutic challenges, necessitating a high index of suspicion in patients with atypical spinal cord symptoms. Collaborative efforts between neurosurgical, oncological, and infectious diseases teams are imperative for timely diagnosis and management. Advancements in diagnostic precision and therapeutic options are crucial for improving patient outcomes.

Abstract
Compared with those involving the central nervous system, lymphomas involving the peripheral nervous system, namely neurolymphomatosis, are extremely rare. Neurolymphomatosis is classified as primary or secondary; the former is much rarer than the latter. Herein, we present an autopsied case of primary cauda equina lymphoma (PCEL), a type of primary neurolymphomatosis, with a literature review of autopsied cases of PCEL as well as primary neurolymphomatosis other than PCEL (non-PCEL primary neurolymphomatosis). A 70-year-old woman presented with difficulty walking, followed by paraplegia and then bladder and bowel disturbance. On magnetic resonance imaging, the cauda equina was diffusely enlarged and enhanced with gadolinium. The brainstem and cerebellum were also enhanced with gadolinium along their surface. The differential diagnosis of the patient included meningeal tumors (other than lymphomas), lymphomas, or sarcoidosis. The biopsy of the cauda equina was planned for a definite diagnosis, but because the patient deteriorated so rapidly, it was not performed. Eventually, she was affected by cranial nerve palsies. With the definite diagnosis being undetermined, the patient died approximately 1.5 years after the onset of disesase. At autopsy, the cauda equina was replaced by a bulky mass composed of atypical B-lymphoid cells, consistent with diffuse large B-cell lymphoma (DLBCL). The spinal cord was heavily infiltrated, as were the spinal/cranial nerves and subarachnoid space. There was metastasis in the left adrenal. The patient was finally diagnosed postmortem as PCEL with a DLBCL phenotype. To date, there have been a limited number of autopsied cases of PCEL and non-PCEL primary neurolymphomatosis (nine cases in all, including ours). The diagnosis is, without exception, B-cell lymphoma including DLBCL, and the histology features central nervous system parenchymal infiltration, nerve root involvement, and subarachnoid dissemination (lymphomatous meningitis). Metastases are not uncommon. All clinicians and pathologists should be aware of lymphomas primarily involving the peripheral nervous system.

Abstract
Primary cauda equina lymphoma is an extremely rare entity previously documented in only 24 reported cases. Primary cauda equina lymphoma represents a subtype of neurolymphomatosis, which occurs when lymphoma cells with neurotropism infiltrate and destroy peripheral nerves, spinal nerve roots, nerve plexuses and cranial nerves. The cauda equina is an anatomic structure located in the lower part of the spinal canal consisting of multiple lumbar and sacral nerve roots. Herein, we report a unique case of primary cauda equina diffuse large B-cell lymphoma presenting as a tumor mass in the lower spinal canal, which was treated with a CNS-centric treatment approach followed by autologous hematopoietic stem cell transplantation.

Abstract
BACKGROUND T-cell lymphoblastic lymphoma (T-LBL) is a rare and aggressive form of non-Hodgkin lymphoma. This report describes, to our knowledge, the first adult case of a primary cauda equina T-LBL. Treatment consists of multiagent chemotherapy, and surgical removal of T-LBL does not improve outcome. We discuss the workup of patients with an intradural spinal mass, together with a review of the literature on primary spinal lymphoma of the cauda equina. CASE DESCRIPTION A 54-year-old woman with Crohn's disease, for which she was taking immunosuppressive medication, presented with progressive back pain radiating to both legs and deteriorating neurologic deficits caused by an intradural, contrast-enhancing lesion in the L1-5 region. During acute surgery, the tumor was partially resected. Immunohistochemical phenotyping revealed a T-LBL. No other lymphoma localizations were found after subsequent staging. Despite extensive treatment, the patient died of disseminated disease throughout the central nervous system, 6 weeks after the diagnosis. CONCLUSIONS Pain and progressive neurologic complaints can be symptoms of a (malignant) intradural spinal tumor. Intradural lymphoma must be considered as a differential diagnosis by clinicians because it can mimic neoplasms that often require urgent surgery. The histopathologic diagnosis should preferably be obtained by way of cerebrospinal fluid analysis or tumor biopsy because tumor resection has no beneficial effect on the oncologic outcome.

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
Primary cauda equina lymphoma (CEL) is a rare malignant tumor among various neoplasms that affects the cauda equina nerve roots. The present case report described the case of a 65-year-old man who presented with cauda equina syndrome with progressive motor palsy in the legs and gait disturbance over the last 5 months. Magnetic resonance (MR) images showed enlargement of the cauda equina occupying the dural sac from the L1-S1 level with isointensity to the spinal cord signal on both T1- and T2-weighted imaging. Enhancement of the cauda equina was seen on contrast MR images. On F-18 2-fluoro-2-deoxy-glucose positron emission tomography examination, diffuse accumulation of 2-fluoro-2-deoxy-glucose was observed in the cauda equina with a maximum standardized uptake value of 4.9. Based on elevation of soluble interleukin 2 receptor in cerebrospinal fluid and a biopsy of the enlarging cauda equina, a diagnosis of CEL of the diffuse large B-cell type was made. The present case report provided a detailed case discussion and a review of the available literature on this rare entity, focusing on clinical characteristics and imaging of primary CEL.

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
Primary malignant lymphoma of the cauda equina is an extremely rare disease. Previously, there have been only 12 reported cases of malignant lymphoma of the cauda equina, and most cases relapsed early in the clinical course. So, the optimal treatment strategy for this condition has not been established yet and the prognosis is thought to be poor. We experienced a case of B-cell malignant lymphoma of the cauda equina, with rapid progression of the muscle weakness of the bilateral lower extremities, successfully treated with high-dose methotrexate plus high-dose cytarabine (Ara-C) chemotherapy, followed by radiotherapy and in complete remission without any recurrence signs, 1.5 years after the initial diagnosis. Intrathecal chemotherapy with MTX, Ara-C, and predonisolone was simultaneously performed. We should carefully continue to monitor the clinical course of our case, with the examinations of magnetic resonance imaging and cerebrospinal fluid in order not to overlook any subtle neurological changes or other clinical symptoms.

Abstract
Although rare, direct infiltration of the cauda equina by non-Hodgkin's lymphoma (NHL) must be considered as a potential cause of subacute onset paraplegia. We present two cases of lymphomatous involvement of the cauda equina presenting with subacute paraplegia, each associated with a palsy of an oculomotor nerve. We highlight the need to use gadolinium-enhanced magnetic resonance imaging (MRI) when investigating potential cauda equina lesions, since it is crucial in detecting and outlining the extent of disease. Differential diagnoses and treatment options for NHL involving the cauda equina are also discussed.

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
A patient with coeliac disease developed a progressive cauda equina syndrome in the 2 months prior to his death, for which no cause could be identified. At post-mortem examination this proved to be due to disseminated enteropathy-type T-cell lymphoma. Although rare, disseminated enteropathy-type T-cell lymphoma should enter the differential diagnosis in any patient with coeliac disease developing new neurological signs.

Abstract
Malignant lymphoma of the central nervous system is usually confined within the cranium, with primary involvement of the spinal cord and nerve roots being very rare. The occurrence of primary lymphoma in the cauda equina in a 16-year-old Chinese male is reported. Contrast enhancement during magnetic resonance imaging is useful in accurately demonstrating disease extent prior to surgery.

Abstract
A wide spectrum of central and peripheral nervous system abnormalities may be associated with HIV infection. These disorders may be caused by HIV infection, result as secondary complications related to immunosuppression, or be a neurotoxic effect of therapeutic agents. The range of neurologic disorders includes dementia, focal cerebral mass lesions, myelopathy, peripheral neuropathies, and myopathy. Early diagnosis and therapy is critical, and may result in substantial improvement in patients' quality and quantity of life. This article reviews the approach to differential diagnosis of these neurologic disorders and presents theories of pathogenesis and current approaches to treatment.

Abstract
We reviewed our experience in 23 patients with acquired immunodeficiency syndrome (AIDS) who had acute lumbosacral polyradiculopathy. The patients developed a distinctive syndrome of rapidly progressive flaccid paraparesis and areflexia that was frequently associated with sphincter disturbances. Persuasive laboratory evidence of a cytomegalovirus polyradiculopathy (polymorphonuclear pleocytosis or confirmatory cerebrospinal fluid culture) was found in 15 of the 23 patients. Treatment with ganciclovir in these patients led to clinical stabilization, although worsening during the first 2 weeks of treatment was common. Most patients with cytomegalovirus polyradiculopathy had severe residual deficits. Metastasis from systemic lymphoma accounted for the polyradiculopathy in 2 other patients. A more benign syndrome was identified in the remaining 6 patients. They generally had slower clinical progression and less severe neurological deficits at their nadir than did patients with cytomegalovirus polyradiculopathy. Unlike patients with cytomegalovirus infection, their cerebrospinal fluid showed a predominantly mononuclear pleocytosis. Moreover, spontaneous improvement without treatment was common. Our experience together with the published experience of others suggests that the acute lumbosacral polyradiculopathy in AIDS is a clinical syndrome with different etiologies and variable clinical outcome. Recognition of this heterogeneity is necessary for the management of individual patients, as well as the interpretation of treatment results.

Abstract
Primary CNS lymphomas (PCNSL), until recently representing about 1% of all brain tumors, show dramatically increased incidence both in high-risk groups (immunocompromised, AIDS) and in the general population. They are extranodal diffuse non-Hodgkin's lymphomas, the morphology and classification of which are identical to those of systemic lymphomas, although PCNSL show different biological behavior and diagnosis according to the New Working Formulation and updated Kiel classification may be difficult. The majority are large B cell variants of high-grade malignancy; low-grade subtypes and T cell lymphomas are rare. Sixty per cent occur in the supratentorial space (hemispheres, periventricular) and 12% in the posterior fossa; 30% are multiple (50%-70% in AIDS). PCNSL show a male preponderance with a peak incidence in the 5th-7th decade (3rd-4th in AIDS). The duration of diffuse or focal clinical symptoms averages 1-2 months. Computed tomography and magnetic resonance imaging scans show single or multiple or diffuse, often typical lesions. Diagnosis is achieved by evaluation of stereotactic biopsy material or cerebrospinal fluid cytology using immunocytological markers. Current therapy in immunocompetent patients, radiation plus corticosteroids and pre- or postradiation polychemotherapy, shows response rates of 85% with a median survival of 17-44 months, a prognosis similar to that for glioblastoma. Meningeal PCNSL is treated with intrathecal methotrexate or cytosine arabinoside. Transliquoral seeding of PCNSL is frequent, distant metastases occurring in 6%-8%. Therapy of AIDS-related PCNSL makes use of radiation and corticosteroids, and rarely of chemotherapy. The pathogenesis of PCNSL is unknown, but Epstein-Barr virus may be a contributory factor.
