A mass is a space occupying tumor that has three dimensions. Usually, it has a visible correlate on pre-contrast T1- or T2-weighted images. In fact, the definition of a mass is quite comparable to the term used in mammography. As opposed to a “mass”, non-mass-like enhancement means enhancement in …

intense with T2-weighted or fluid-sensitive se-quences due to the prolonged T2 relaxation time of water (1). Besides truly cystic lesions such as ganglia or bursae, there are some solid masses that can also appear to be very T2 hyperintense. These lesions have been described as “cystlike” lesions by some authors (2) and can simulate the T2
