Intravascular lymphomatosis is a rare extra-nodal form of diffuse, large B-cell non-Hodgkin's lymphoma that causes a myriad of neurological symptoms, including focal neurological deficits, cognitive decline, and seizure. Intravascular lymphomatosis is difficult to make ante-mortem diagnosis because of its variable clinical presentation and non-specific laboratory findings. Neuroimaging findings also vary widely in patients of intravascular lymphomatosis. We present, herein, a patient with rapidly deteriorating neurological deficit whose brain MRI revealed rapidly progressing white matter diseases. This patient was diagnosed and treated as having a cerebral demyelinating disorder. Intravascular lymphomatosis involving multiple organs was finally diagnosed after autopsy.

We present a 31-year-old female patient with primary non-Hodgkin's lymphoma of the CNS after immunosuppressive therapy. Colitis ulcerosa had been diagnosed 2 years previously. Prophylactic therapy with azathioprine over 9 months was stopped after the development of listeria meningitis which was treated successfully with antibiotics. At this time native CCT was normal. Three months later the patient developed an epileptic seizure and multiple cerebral lesions were detected in CCT and MRI. Although antibiotic therapy was started, the cerebral lesions showed no regression. Stereotactic biopsy revealed immunochemical and histologic high-grade malignant B cell lymphoma. The risk of primary CNS lymphoma under azathioprine treatment for an autoimmune disease with a possible congenital immunodeficiency is presented and the literature is reviewed.

We describe a case of hairy cell leukaemia (HCL) coexistent with non-Hodgkin's lymphoma (NHD). This combination is reported to be extremely rare with no clear demonstration of the clonal relationship between the two conditions. After a previous failure of purine analogue therapy, our patient was successfully treated with rituximab resulting in normalisation of blood cell count cessation of blood transfusion and negative iliac crest biopsy. Unfortunately, the patient developed intense and persistent bone pain during the 1(st) line treatment for HCL. Skeletal X-rays, neck-thorax-abdomen CT scan and repeated bone MRI were unremarkable and bone scintigraphy showed non-specific changes. Laboratory examinations were normal. To better evaluate bone scintigraphy results, we finally performed FDG-PET/CT, which showed multiple foci of intense abnormal radiotracer uptake involving the bone marrow. An FDG-PET/CT guided bone marrow biopsy showed primary bone marrow diffuse large B-cell lymphoma (LBCL). Despite 2(nd) and 3(rd) line treatment, the patient died shortly after for central nervous system involvement by NHD. The role of FDG-PET/CT in identifying bone and bone marrow localization of NHD is reviewed and an earlier use is suggested in poorly understood bone pain.

This case illustrates a pitfall associated with F-18 FDG imaging. We present the images of a 57-year-old woman with non-Hodgkin's lymphoma that shows intense accumulation of F-18 FDG in a sacrococcygeal pilonidal sinus that could indicate a lymphomatous involvement from a primary disease. MRI showed a well-defined sinus tract from skin to the sacrococcygeal region corresponding to the F-18 FDG uptake. She did not have any symptoms of a sacrococcygeal pilonidal sinus such as discharge, swelling or pain. There was no visible opening of the sinus tract on the skin. Pilonidal sinus is commonly a hair-containing sinus or abscess in the sacrococcygeal area. Hair acts as a foreign body causing an inflammatory reaction.

Primary central nervous system lymphoma (PCNSL) can be associated with preceding demyelinating pseudotumoral brain lesions. The 'sentinel' demyelinating lesions recede spontaneously or with corticosteroid, and are followed by development of PCNSL typically within 12 months. This report describes a 29 year-old post-partum woman who developed PCNSL 4 years after a biopsy-proven pseudotumoral demyelinating episode. She presented with focal seizures in February 2005. She subsequently developed hemiparesis and raised intracranial pressure. MRI showed two contrast enhancing lesions in the right frontal lobe, which were hypermetabolic on (18)F-FDG PET. A provisional diagnosis of tumefactive multiple sclerosis was made. Symptoms recurred despite multiple courses of high dose corticosteroid. Brain biopsy confirmed large B-cell non-Hodgkin's lymphoma. This patient illustrates the importance of considering PCNSL in patients presenting with a space-occupying lesion, even with previously confirmed demyelination, and that the interval between the two events may be several years.

Treatment for patients with refractory or relapsed primary CNS lymphoma (PCNSL) remains unsatisfactory. Topotecan is an intravenous topoisomerase I inhibitor with good CSF penetration and documented efficacy in patients with relapsed systemic non-Hodgkin's lymphoma. In this study 15 patients with refractory or relapsed PCNSL were treated with intravenous topotecan (1.5 mg/m(2)) for five consecutive days during each 21-day cycle. All 15 patients had measurable, contrast-enhancing tumor on cranial MRI at the time of relapse. Three (20%) patients achieved a complete response after one, three and four cycles, respectively, while three (20%) patients achieved a partial response after two cycles each, for a total response proportion of 40%. Three patients had stable disease at the end of topotecan treatment. Six patients (40%) had progressive disease during treatment. Median overall survival was 981 days (95% CI: 275, NA) and median progression free survival was 60 days (95% CI: 46, 945). Three out of 15 patients had grade 3 thrombocytopenia. Six out of 15 patients had grade 3 neutropenia, while 5/15 patients had grade 4 neutropenia, and 13/15 patients received g-CSF at some point during treatment. There were no deaths directly related to treatment toxicity. Our study shows that topotecan, as a salvage therapy in patients with relapsed or refractory PCNSL, is associated with an overall response proportion of 40% and should be considered in patients who have failed prior methotrexate-based chemotherapy and/or whole brain irradiation. However, progression is frequent and early and most patients required growth factor support due to myelotoxicity.

Neurolymphomatosis (NL) is lymphomatous infiltration of peripheral nerves, and is an uncommon manifestation of non-Hodgkin's lymphoma (NHL). Although nerve biopsy is the main method for histological diagnosis, a blind nerve biopsy may not be diagnostic. While CT and MRI have been used to detect NL, recent reports demonstrated the benefit of integrated positron emission tomography (PET) using F18-2-fluoro-2-deoxy-D-glucose (FDG) combined with computed tomography (CT). We described the utility of FDG PET-CT in this uncommon subgroup of NHL where it can assist in establishing the diagnosis, the potential to guide sites for biopsy and in the assessment of response to therapy.

Burkitt's lymphoma is a rare disease that belongs to the aggressive non-Hodgkin's lymphoma. Herein, we report a case of primary hepatic Burkitt's lymphoma. A 19-year-old man visited the hospital for right upper quadrant pain. He felt fatigue for two months. Physical examination revealed hepatomegaly and no palpable lymph node. He had no fever, weight loss, or night sweating. Laboratory finding showed mild anemia (hemoglobin, 12.4 g/dL), mild elevated transaminase (ALT, 52 IU/L), elevated lactate dehydrogenase (LDH, 437 IU/L), and alkaline phosphatase (ALP, 129 IU/L). The viral marker was positive for HBsAg, HBeAg, anti-HBs, and anti-HBc (IgG), and negative for anti-HBe, anti-HCV, and anti-HIV. CEA, AFP, and CA19-9 levels were within normal ranges. The HBV DNA quantitation was 1.3 x 10(9) copies/ml. Abdominal-Pelvis CT scan and abdominal MRI finding were compatible with malignant lymphoma. Liver biopsy examination confirmed Burkitt's lymphoma. No metastasis was detected in the thoracic cavity, bone marrow, and spinal fluid. The patient was treated with the combination regimen of cyclophosphamide, doxorubicin, vincristine, prednisone and high dose methotrexate. Cytosine arabinoside and methotrexate were added for CNS prophylaxis by intrathecal installation. Chemotherapy was administered every 3 weeks for fifteen cycles. Serial follow-up CT scan showed a marked decrease in the size of hepatic lesions. Follow-up CT scan and PET-CT scan were performed 4 weeks after the final cycle disclosed no definite residual or active lesion confirming the state of complete remission.

Herein is described a mesenteric diffuse large B cell lymphoma (DLBCL) case with a bulky mass which had achieved a complete remission by the combination therapy of a surgical resection and the CHOP chemotherapy with rituximab. A 78 year old man was referred to the Rakuwakai-Otowa Hospital due to a left lower abdominal tumor. Abdominal CT and MRI showed a bowel-like mass in the left lower abdominal cavity. Abdominal US revealed lymph node swellings at the paraaortic region. By the gastro-duodenoscopy, DLBCL of non-Hodgkin's lymphoma was proven at the 2nd portion of the duodenum. On laparotomy, a mass of 8x8cm in size was found at the mesenterium of the ileum, which directly invaded the ileum and the sigmoid mesocolon. A partial resection of the ileum and the sigmoid colon was performed. After the operation, it was determined to be Stage IV DLBCL and the chemotherapy based on the R-CHOP regimen was performed. The regimen was repeated to the 6th course. During the chemotherapy, he was confirmed to have achieved a complete remission. The present case is a rare case in which a Stage IV mesenteric DLBCL with extensive bulky masses had a favorable prognosis. Stage IV mesenteric DLBCLs with extensive bulky masses are thought to be the indication for the combination therapy of surgical resection and multiagent chemotherapy with rituximab.
