Fig. (2) A 54-year-old male with a medium size epidermal cyst at the knee. The MRI displays a well-defined oval-shaped lesion with a rather monotonous signal that was hyperintense relative to muscle on a T1-weighted image (A) and high signal intensity on a T2-weighted image without (B) and with (C) fat suppression. Keratinized material, comprised of intracyst debris or a peripheral lining, is not apparent on the T1- and T2-weighted MRIs.
