Patient Data

Age: 85 years
Gender: Male
CT

Multiple hyperdense mass lesions throughout the brain.  Most do not have surrounding vasogenic edema but some do as is typical of metastases.

Case Discussion

Hyperdense metastases to the brain are unusual and include the primary sites of lung, breast, GI tract and melanoma as in this case.  The density in melanoma is either due to blood product (hemorrhagic mets) or the melanin itself.  Calcifaction can also cause increased density in metastases including post radiotherapy.
