Signal intensity is a feature of paramount importance in the MRI assessment of these synovial lesions. The pontine areas that were hyperintense on T2W MRI showed white matter pallor with reactive astrocytosis, primarily in the central parts of the pons, with arteriosclerotic changes in the small arteries. The vast majority of focal liver lesions are hyperintense on T2-weighted magnetic resonance (MR) images. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient.
