Comment on Neuropathology. 2008 Dec;28(6):640-4 Case 259: Primary Central Nervous System Lymphomatoid Granulomatosis Mimicking Chronic Lymphocytic Inflammation with Pontine Perivascular Enhancement Responsive to Steroids (CLIPPERS Lymphomatoid granulomatosis is a rare disorder characterized by overproduction (proliferation) of white blood cells called lymphocytes (lymphoproliferative disorder). The abnormal cells infiltrate and accumulate (form lesions or nodules) within tissues. The lesions or nodules damage or destroy the blood vessels within these tissues Patients with lymphomatoid granulomatosis are usually quite ill with pulmonary manifestations. In our study, lymphomatoid granulomatosis initially manifested purely as a CNS disease that was later followed by histologically proved abdominal involvement and radiologic evidence of chest involvement

[A Case of Primary Central Nervous System Lymphomatoid

Lymphomatoid granulomatosis (LG) is an uncommon but potentially fatal disease. The disease primarily involves the lungs; however, skin, renal, and central nervous system (CNS) are seen in varying proportions. Neurological involvement occurs in one third of the patients, and confers a worse prognosis A diagnosis of isolated central nervous system lymphomatoid granulomatosis (CNS-LYG) was made based on the brain biopsy findings. The complete remission of CNS-LYG was achieved by anti-retroviral therapy (ART) alone. In the present case, the development of AIDS-associated CNS-LYG was considered to have been initiated by the reactivation of EBV. The clinical CT and MR imaging features of a pathologically confirmed case of lymphomatoid granulomatosis are presented. The disease was clinically confined to the central nervous system and the diagnosis was only made after brain biopsy had been performed. MR imaging revealed extensive non-confluent regions of white matter abnormality Lymphomatoid granulomatosis (LYG) in the CNS is an uncommon lymphoproliferative disease with characteristic angiocentric lymphoreticular proliferative and granulomatous lesions exhibiting low‐grade malignant potential. Here we report a rare case of CNS‐LYG, which disseminated to the lymph node and bone marrow Lymphomatoid granulomatosis (LG) is an uncommon multisystem disease characterized by multifocal angiocentric angiodestructive lymphoreticular proliferative and granulomatous lesions (1). LG involves the lungs most frequently, followed by the skin and brain (2)

CONCLUSION: Lymphomatoid granulomatosis has a high rate of central nervous system involvement and a variable spectrum of lesions at MR imaging. Findings in this study suggest that MR imaging is more sensitive than CSF cytologic analysis or flow cytometry for detection of central nervous system involvement from lymphomatoid granulomatosis Radiotherapy to Control CNS Lymphomatoid Granulomatosis: A Case Report and Review of the Literature Teresa M.

However, isolated CNS involvement is rare,2,3 and its clinical features are variable Objectives Lymphomatoid granulomatosis is a rare Epstein Barr virus (EBV) associated lymphoproliferative disorder. It most commonly involves the lung, but may also include other extra-nodal sites such as skin and central nervous system (CNS) to a lesser extent.[1][1] Due to the insidious nature of the condition, along with variable radiological findings, it remains a diagnostic challenge.[1,2. An 80-year-old woman presented with weight loss, fatigue, dizziness and a brain stem lesion. Extensive work-up revealed lymphomatoid granulomatosis (LYG) with primary clinical manifestation in the central nervous system (CNS), a rare Epstein-Barr virus-driven multisystem lymphoproliferative disorder, to be causative for the symptoms

Lymphomatoid granulomatosis (LYG) in the central nervous system (CNS) is an uncommon lymphoproliferative disorder with low grade malignant potential. Here we report a case of CNS-LYG, in particular, its characteristics of radioisotope imaging and pathological findings. A 65-year-old man complained of visual disturbance and homonymous hemianopsia was designated. CT and MRI revealed an edematous. We read with great interest the article by Takiyama et al. describing a case of CNS lymphomatoid granulomatosis (LYG). The authors indicated that the infiltrating cells in the brain consisted of small lymphocytes without overt nuclear atypism in the perivascular areas, and that the lymphocytes were mainly CD3-positive, and rarely CD20positive

Lymphomatoid granulomatosis (LYG) is a rare lymphoproliferative disorder with a mortality rate approaching 60% in the first year. The median survival is 14 months from the time of diagnosis. Although a variety of chemotherapeutic regimens have been utilized, there is no standard treatment. Studies have shown that in most cases the malignant cells are B-cells, which induce massive infiltration. Background: Lymphomatoid granulomatosis (LYG) is a rare EBV-driven B-cell lymphoproliferative disorder characterized by a reactive T-cell infiltrate that is angioinvasive and angiodestructive. Dysregulated immune surveillance of EBV is thought to contribute to the pathogenesis of LYG and grading of disease is based on the density and number of EBV+ large atypical B-cells Lymphomatoid granulomatosis of the central nervous system is uncommon, but represents the second most common site of involvement in patients with systemic lymphomatoid granulomatosis, after the lungs, which are most commonly involved.It is considered one of the immunodeficiency-associated CNS lymphomas under the current (2016) WHO classification of CNS tumors
