A 60-year-old woman with no previous history of chronic disease or malignancy presented with intense back and left leg pain and sleep disturbances. The patient had been treated unsuccessfully for the past 6 months with analgetics. Magnetic resonance imaging showed a soft tissue tumor in the L5-S1 region that involved the spinal canal, and a pathohistological analysis of the tumor specimen confirmed the presence of non-Hodgkin, diffuse large B cell lymphoma. After the diagnosis was confirmed, malaise, nausea, and vomiting developed. Multislice computed tomography of the endocranium showed focal infiltration of the hypothalamus and lateral ventricle; dissemination of a systemic lymphoma was excluded. Therapy was initiated as per the De Angelis protocol. After intravenous and intrathecal administration of metotrexate, the patient developed signs of central diabetes insipidus, which responded to therapy with an antidiuretic hormone analog. Despite the obvious infiltration of the hypothalamus, we cannot exclude an idiosyncratic effect of methotrexate on the central diabetes insipidus.

A 68-year-old retired nurse, who was a known hypertensive on medication, presented with prolonged fever of 2-month duration without any clinical evidence of infection. On examination she had altered mental status. She also had other nonspecific complaints such as sleep disturbances, loss of weight, etc. On investigation, she was found to have anemia, thrombocytopenia, raised erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and lactate dehydrogenase (LDH) values. She also had electrolyte imbalance. Radiological evaluation of brain showed mass lesion in the sella turcica, suggestive of pituitary adenoma. Biochemical evaluation showed hypopituitarism. Trans-sphenoidal biopsy was done. Based on histopathological and immunohistochemical findings a diagnosis of intravascular large B-cell lymphoma (IVLBCL) of pituitary was made. Our patient's condition deteriorated rapidly and she succumbed to her illness before therapy could be initiated. We are reporting this case because of the rare subtype of large B-cell lymphoma presenting at an extremely unusual primary site.

Exposure to traffic noise may result in stress and sleep disturbances, which have been associated with impairment of the immune system. People with weakened immune systems are known to have a higher risk for non-Hodgkin lymphoma (NHL). We aimed to determine whether traffic noise was associated with risk for NHL in a nationwide case-control study. We identified 2753 cases aged 30-84 years with a primary diagnosis of NHL in Denmark between 1992 and 2010. For each case we selected two random population controls, matched on sex and year of birth. Road traffic and railway noise were calculated, and airport noise was estimated for all present and historical residential addresses of cases and controls from 1987 to 2010. Associations between traffic noise and risk for NHL were estimated using conditional logistic regression, adjusted for disposable income, education, cohabiting status and comorbidity. We found that a 5-year time-weighted mean of road traffic noise above 65 dB was associated with an 18% higher risk for NHL (95% confidence interval (CI) 1.01-1.37) when compared to road traffic noise below 55 dB, whereas for exposure between 55 and 65 dB no association was found (odds ratio: 0.98; 95% CI: 0.88-1.08). In analyzes of NHL subtypes, we found no association between road traffic noise and risk for T-cell lymphoma, whereas increased risks for B-cell lymphoma and unspecified lymphomas were observed at exposures above 65 dB. In conclusion, our nationwide study may indicate that high exposure to traffic noise is associated with higher NHL risk.
