Temporomandibular joint pathosis related to sex, age, and dentition in autopsy material
The purpose of this autopsy study was to test the hypotheses that temporomandibular joint (TMJ) arthrosis is more common in women than in men, increases with age, and is more common in edentulous persons than in those with natural teeth. Two hundred forty-eight TMJs removed at autopsy from 224 fresh cadavers were investigated macroscopically with dissection or cryosectioning. Age was found to be a significant factor in prediction of TMJ arthrosis (p p p p < 0.001) between arthrosis, disk displacement, disk deformation, and disk perforation. There were no statistically significant differences in the prevalence of morphologic changes in the joints from persons with 10 or more natural teeth in each jaw compared with those from persons without natural teeth. The results of this study showed that TMJ arthrosis is more frequent in older than in younger persons. TMJ disk displacement generally appears necessary for the development of perforations. The findings of this study indicate that sex and dentition are not major factors for the development of TMJ pathosis in elderly individuals.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31264/1/0000170.pd
MR images mimic disc after discectomy
MRI of a 30-year-old woman 1 year after discectomy showed a residual disc-like tissue. The observation was initially confusing, but a close comparison of pre- and post-operative images suggested that the inferior wall of the anterior joint capsule had migrated superiorly after the removal of the disc and mimicked a residual disc on the follow-up MR images

Diffusion-weighted MR imaging of neuro-Behçet\u27s disease: a case report.
We present a serial study of diffusion-weighted imaging (DWI) in a patient with neuro-Behçet\u27s disease. Initial T2-weighted magnetic resonance images showed a hyperintense lesion in the brain stem. The lesion was slightly hyperintense on DWI and the apparent diffusion coefficient (ADC) was slightly increased. Ten months later, DWI showed an improvement in the abnormal signal intensity and the region of increased ADC had increased in size, especially on the left side. DWI is useful for differentiating an acute exacerbation of neuro-Behçet\u27s disease from acute infarction
