Case Reports
Magnetic resonance imaging and diffusion tensor analysis of lymphomatoid granulomatosis of the brain.
We present the case of a 56-year-old man suffering from acquired immune deficiency syndrome associated with lymphomatoid granulomatosis. Magnetic resonance imaging performed because of convulsions revealed an ill-defined frontal mass showing hypointense on T1WI and slightly hypointense on T2WI with surrounding edema. ⋯ However, the apparent diffusion coefficient ratio calculated from diffusion-tensor acquisitions was 1.53 and was higher than that of lymphomas in previous reports. Stereotactic brain biopsy was performed and lymphomatoid granulomatosis was confirmed.

A 23-year-old woman was transferred to our department with loss of consciousness 6 h after undergoing rod placement for thoracolumbar scoliosis. Both computed tomography and magnetic resonance imaging of the brain revealed diffuse pneumocephalus and infra- and supratentorial hemorrhages. ⋯ The patient was re-operated and the dural tear was repaired. To our knowledge, this is the first description of these uncommon complications in one patient after spine surgery.

To evaluate whether increased written information to patients prior to magnetic resonance imaging (MRI) decreases patient anxiety and image motion artifacts. ⋯ Increased information about the MRI scanning procedure and expected experiences during the scan may help patients to lie still during the sequences, with a decrease in motion artifacts. However, further research is needed to evaluate the effect of other interventions on patient anxiety during MRI scanning.
