We report a case of primary central nervous system(CNS) lymphoma in an organ recipient. A 33-years-old man who underwent a renal transplantation 3years previously presented with headache and vomiting. In Brain computed tomography scans and magnetic resonance images showed multiple periventricular cystic rim enhancing masses. Pathologic diagnosis by stereotactic biopsy revealed malignant non-Hodgkins B-cell lymphoma. After pathologic confirmation, methotrexate chemotherapy and whole brain radiation therapy were done. Having experienced such a case, the authors strongly recommend to add primary CNS lymphoma as one of the differential diagnoses to brain abscess, metastatic brain tumor and glioblastoma multiforme in cases of multiple ring enhancing periventricular lesions of immunocompromised patient or organ recipient.

Primary central nervous system lymphoma (PCNSL) is a type of non-Hodgkin lymphoma confined to the central nervous system. Its diagnosis requires a stereotactic biopsy, which is an invasive procedure. Cerebrospinal fluid (CSF) analysis is less invasive and easier to perform than a stereotactic biopsy. We hereby report a PCNSL case diagnosed using CSF analysis and treated with systemic chemotherapy.

Objectives The purpose of this case study was to report improvements of a Soeumin patient with sweating and palpitation after chemotherapy for primary central nervous system lymphoma by diagnosing and treating as Yang Depletion Symptomatology. Methods The Soeumin patient was administered Bojungikgi-tang and treated with acupuncture. Global assessment scale (GAS) was used to assess the improvements of symptoms. Results Sweating was improved to GAS 20 and palpitation was gone away after using Sasang constitutional medicine treatment. Conclusions This study shows that Sasang constitutional medicine can be effective treatment for side effects caused by chemotherapy for cancer.

Purpose: We evaluated $^1H$ MR spectroscopy improves the preoperative diagnosis of diffuse infiltrative type of primary central nervous system lymphomas. Materials and methods: After review of conventional MR images and medical records, we retrospectively reviewed proton MR spectra in seven patients with primary central nervous system lymphoma diagnosed by means of biopsy. Relative ratio of choline (Cho), N-acetylaspartate (NAA), and lipid-lactate (Lip-Lac) to creatine (Cr) were measured for quantitative analysis. Results: The average ratio of Cho/Cr was $1.80{\pm}0.95$, NAA/Cr was $1.34{\pm}0.41$, and Lip-Lac/Cr was $1.12{\pm}0.16$. All cases of lymphomas showed increased Lip-Lac peak. Two case of mass forming lymphoma showed decreased NAA/Cr significantly, whereas five cases of lymphoma without mass formation showed preserved NAA/Cr. Conclusion : We thought the presence of Lip-Lac peak without significant reduction of NAA on the MR spectroscopy was helpful for diagnosis of diffuse infiltrative type of central nervous system lymphoma.

Mucosa-associated lymphoid tissue (MALT) lymphoma is one of the most common lymphomas and accounts for about 7% of all newly diagnosed non-Hodgkin's lymphoma (NHL). The clinical course of MALT lymphoma is relatively indolent and, in the majority of cases (50%), the lymphoma arises within the stomach. Primary central nervous system lymphoma (PCNSL), an uncommon variant of extranodal NHL, can affect any part of the neuraxis, including the eyes, brain, leptomeninges, or spinal cord. Herein, we present a rare case of PCNSL, which occurred one year after radiochemotherapy of gastric MALT lymphoma. A 62-year-old man presented with a 3-day history of left facial palsy. One year ago, he underwent antibiotic eradication therapy of Helicobacter pylori, local stomach fractional radiotherapy, and chemotherapy for gastric MALT lymphoma. Magnetic resonance imaging revealed a strong enhancing solid mass in the right frontal lobe. The tumor was completely removed, and the histological diagnosis of PCNSL developing from diffuse large B-cell lymphoma was made. Although elucidating the correlation between the first gastric MALT lymphoma and the second PCNSL seemed difficult, we have postulated and discussed some possible pathogeneses, together with a review of literature.

Primary central nervous system T-cell lymphoma (PCNSTL) is an extremely rare type of brain tumor. There are only few reports on the imaging findings of patients with PCNSTL. Herein, we report the imaging findings of a patient with peripheral T-cell lymphoma-not otherwise specified that presented with numerous small nodular and patchy strongly enhancing lesions on MRI.

In trauma patients, cognitive impairment may develop due to several causes: traumatic brain injury such as intracranial hemorrhage, diffuse axonal injury, hypoxic brain injury or reperfusion injury, the psychologic disorder, such as acute stress disorder, post-traumatic disorder or delirium. We describe a 62-year-old male with post-trauma cognitive impairment due to a primary central nervous system lymphoma.

Background and Aim: The incidence of extra nodal non Hodgkin lymphoma (ENL) is rising throughout the world. However, data regarding ENL as a group is limited. The aim was to study the epidemiological and histomorphological trends of primary ENL (pENL) in India. Material and Methods: The biopsy materials from sixty eight patients with pENL (45 male, 23 female, M:F= 1.9:1), diagnosed over a five year period (2005-2009), were analysed and pathologically reclassified according to the World Health Organization (WHO) classification, 2008 criteria. Results: Primary extra nodal non Hodgkin lymphomas constituted 22.0% (68/308) of all non Hodgkin lymphomas (NHL). The mean age at presentation for pENL and primary nodal NHL was 43 years and 58 years, respectively with a male predilection (M: F=2:1). Central nervous system (CNS) constituted the most common extranodal site (20/68, 29.5%) followed by gastrointestinal tract (17/68, 25%), and nose/nasopharynx (8/68, 11.8%). Diffuse large B-cell lymphoma (DLBCL, not otherwise specified), extranodal marginal lymphoma of mucosa associated lymphoid tissue (MALT) type, and B cell NHL unclassified (U) were the three most common histological types observed. T-cell phenotype was rarely noted (4%). Follicular lymphomas and anaplastic large cell lymphoma, seen among nodal NHL, were absent at extra nodal sites. Majority (41/68, 60%) of the patients with pENL were immunocompetent and 55% were in stage I-II with favorable prognosis. Conclusion: Central nervous system was the most common site of ENL, followed by gastrointestinal tract. Majority of pENL occurred in immunocompetent hosts with a favorable prognosis.

Background: The aim of this study was to analyze the clinicopathological and immunohistochemical features of primary central nervous system lymphoma (PCNSL) cases occurring in Indian patients and also study the utility of the crush smear preparation in intraoperative diagnosis. Materials and Methods: The immune status, clinical, radiological details, immunohistochemical profile, histopathological findings and cytological features in smear preparation of 32 cases of PCNSL were analyzed. Patients with systemic NHL and skull-base lymphomas were excluded. Results: The mean age of our patients was 52 years with a male: female ratio 1:1. A periventricular location was found in 62.5% of patients. None of our PCNSL cases were associated with AIDS. All cases except one were diffuse large B-cell lymphomas. Intraoperative diagnosis using crush smears allowed correct prediction in 93% of cases. Conclusions: Our study shows that PCNSL is seen predominantly in immunocompetent patients in India. The age of presentation is relatively young as compared to the West. Our study also stresses the utility of crush smear preparation in establishing an intraoperative diagnosis.

Lymphomatosis cerebri is considered a diffuse form of primary central nervous system lymphoma and very rare. It is not well recognized and may be misdiagnosed with infiltrating tumors, degenerative disorders, ischemic diseases, and infectious diseases developed in the brain. Awareness of the possibility of this rare disease and early biopsy are required for differential diagnosis and preventing poor clinical outcomes. We report a case with lymphomatosis cerebri who presented with rapid neurological deteriorations and review the relevant literatures.
