In cats, lymphoma (lymphosarcoma) is the most common neoplasm affecting the spinal cord and the second most common intracranial tumour. Although lymphoma commonly develops in the spinal cord as a part of a multicentric process, a primary form may occur. Lymphoma can exhibit a wide range of morphological patterns, including intraparenchymal brain mass, lymphomatosis cerebri, intravascular lymphoma, lymphomatous choroiditis and meningitis, extradural, intradural-extramedullary or intramedullary lymphoma in the spinal cord, or neurolymphomatosis in the peripheral nerves...

Tuberculous meningitis is a serious infection caused by Mycobacterium tuberculosis. Early diagnosis is the key to success of treatment. Neuroimaging plays a crucial role in the early and accurate diagnosis of tuberculous meningitis and its disabling complications. Magnetic resonance imaging is considered superior to computed tomography. Neuroimaging characteristics include leptomeningeal and basal cisternal enhancement, hydrocephalus, periventricular infarcts, and tuberculoma. Partially treated pyogenic meningitis, cryptococcal meningitis, viral encephalitis, carcinomatous, and lymphomatous meningitis may have many similar neuroimaging characteristics, and differentiation from tuberculous meningitis at times on the basis of neuroimaging characteristics becomes difficult...

BACKGROUND: Cortical subarachnoid hemorrhage and meningitis sometimes present as episodes of transient neurologic dysfunction mimicking transient ischemic attack (TIA). In the present study, we sought to determine the frequency of meningeal disease among patients treated in a TIA clinic. METHODS: Data from patients consecutively admitted to a TIA clinic were retrospectively analyzed. Patients were classified as ischemic events (TIA or minor stroke) or nonischemic events using clinical data and findings from brain imaging and ultrasound studies...

Dissemination of neoplastic cells into the cerebrospinal fluid (CSF) and leptomeninges is a devastating complication in patients with epithelial cell neoplasia (leptomeningeal carcinomatosis [LC]) and lymphomas (lymphomatous meningitis [LyM]). Information about the surrounding inflammatory cell populations is scarce. In this study, flow cytometry immunophenotyping was used to describe the distribution of the main leukocyte populations in the CSF of 83 patients diagnosed with neoplastic meningitis (LC, n = 65; LyM, n = 18)...

Primary leptomeningeal lymphoma(PLML)is a neoplastic meningitis of lymphomatous origin without parenchymal central nervous system(CNS)disease or a systemic tumor. We report a case of PLML that presented with epileptic seizure, and review relevant literature. A 27-year-old man was brought to the emergency department with an epileptic seizure. Two months later, he was again brought to the emergency department with an epileptic seizure. MRI showed enhanced lesions on the surface of the right cerebellar hemisphere, right parietal sulci, and interhemispheric surface of the frontal lobes...

Neurolymphomatosis (NL) refers to a lymphomatous infiltration of peripheral nerves associated with central nervous system or systemic lymphoma, or alternatively, neurodiagnostic evidence of nerve enhancement and/or enlargement beyond the dural sleeve in the setting of primary central nervous system lymphoma or systemic lymphoma. NL is a rare complication of systemic cancer with heterogeneous clinical presentations and an elusive diagnosis. Diagnosis usually requires the demonstration of infiltrating malignant lymphocytes in the peripheral nerve...

Most primary central nervous system lymphomas (PCNSL) are highly malignant B-cell non-Hodgkin lymphomas. First-line therapy consists of high-dose methotrexate-based chemotherapy with or without whole brain radiotherapy. However, no standard of care is defined for refractory or recurrent PCNSL. We report a patient with lymphomatous meningitis, which was refractory to standard treatment but was successfully controlled for more than 6 years with intraventricular rituximab. Apart from two infections of the Ommaya reservoir, no severe side effects of intraventricular long-term treatment could be detected...

Mantle cell lymphoma (MCL) is an uncommon type of gastrointestinal lymphoma. MCL is a distinct subtype of B-cell non-Hodgkin lymphomas. The major subtype of MCL is characterized by the presence of multiple lymphomatous polyposis (MLP), in which multiple polyps are observed along the gastrointestinal tract. The malignant cells express pan B-cell marker and the T-cell marker cluster of differentiation 5. The chromosomal translocation t(11;14)(q13;q32) that causes cyclin D1 overexpression is commonly observed on the cytogenetic analysis of MCL...

BACKGROUND: Flow cytometry (FC) is considered a sensitive and specific technique for the detection of occult lymphoma cells in cerebrospinal fluid (CSF). METHODS: The diagnostic sensitivity of a FC approach which uses a combination of 10 antibodies, a single-tube evaluation, and a six-color instrument, was evaluated and compared to conventional cytology (CC) for the detection of lymphomatous cells in the CSF of 44 patients affected by B-cell non-Hodgkin's lymphoma (B-NHL) considered at high risk of central nervous system spread...

In patients with neoplastic meningitis (NM), early diagnosis is highly desirable because the rapid institution of intrathecal therapy may mitigate the course of the disease. Cytology, long considered the "gold standard" for diagnosis, has low sensitivity because of both the paucity of cells in the cerebrospinal fluid (CSF) and morphological similarities between benign and malignant cells. A comprehensive review of the literature from 2005 through 2011 was performed that focused on diagnostic modalities for lymphomatous meningitis...

INTRODUCTION: Non-Hodgkin lymphomas (NHLs) constitute a group of heterogeneous diseases that can arise in lymphatic nodal or extranodal sites. Ocular lymphomas account for 1% of all NHLs. Tumor of the orbit, which can lead to compression of the optic nerve, is the most frequent presentation of the disease. Primary infiltration of the optic nerve and its sheath remains exceptional. OBSERVATION: We report the case of a 51-year-old female patient treated for a NHL...

Restricted diffusion in the optic nerve detected with MRI has been previously reported in infarction and inflammation but not in infiltrative neoplasm. We report a 44-year-old man with recently diagnosed non-Hodgkin B-cell lymphoma who developed an acute left optic neuropathy. MRI showed no evidence of brain parenchymal or meningeal lymphoma but did show restricted diffusion in the intraorbital portion of the affected optic nerve. Despite treatment with corticosteroid, standard chemotherapy, and orbital X-irradiation, visual function did not improve...

A prospective study of combined modality therapy of non-AIDS related lymphomatous meningitis was carried out. Lymphomatous meningitis is diagnosed increasingly as anti-lymphoma therapies become more effective and result in prolonged patient survival. Twenty-two patients (range 38-69 years; median 60) with lymphomatous meningitis due to metastatic non-AIDS related non-Hodgkins lymphoma were treated. Neurologic presentation included: headache (n=13); cranial neuropathies (n=9); ataxia (n=5); cauda equina syndrome (n=3); myelopathy (n=1); and meningismus (n=1)...

Primary leptomeningeal lymphoma is a rare syndrome characterized by lymphomatous meningeal infiltration without identification of systemic lymphoma or parenchymal central nervous system lymphoma. We report a case of a 62-year-old immunocompetent woman with primary spinal leptomeningeal lymphoma presenting as cervical and lumbar radiculopathy who is rare because of particularly unusual onset site of B cell lymphoma. Interestingly, the diagnosis was possible only by cerebrospinal fluid flow cytometry.

The neuropathological findings of IVL are characterized by multiple infarctions involving the cerebral cortex and white matter, and infarctions, that do not affect the areas of major arterial supply. Histologically, the disorder is characterized by cerebral necrosis due to intravascular proliferation of tumor cells, with pronounced angiitis or thrombosis. IVL is also associated with frequent spinal cord involvement. At the time of recurrence increasing number of patients with IVL present with findings indistinguishable from those of primary malignant lymphoma of the brain, because advances in the treatment of IVL have increased the follow-up period of these patients...

IMPORTANCE OF THE FIELD: Cytarabine is a polar nucleoside drug used for the treatment of myeloid leukemia and non-Hodgkin's lymphoma. The drug has a short plasma half-life, low stability and limited bioavailability. Overdosing of patients with continuous infusions may lead to side effects. Thus, various prodrug strategies and delivery systems have been explored extensively to enhance the half-life, stability and delivery of cytarabine. Among the recent cytarabine prodrugs, amino acid conjugate ValCytarabine and fatty acid derivative CP-4055 (in Phase III trials) have been investigated for the treatment of leukemia and solid tumors, respectively...
