Presentation
Patient with known kidney malignancy. Rule out metastases.
Patient Data
Age: 70 years
Gender: Male
Axial non-contrast
CT-scan shows multiple cortical-subcortical hypodensities in both hemispheres. In the opercular frontal and parietal region, some of these hypodensities contain hyperdense foci, compatible with hemorrhage. The patient was known for renal cell carcinoma and this is a typical example of hemorrhagic metastases.
Case Discussion
Primary malignancies responsible for hemorrhagic metastases can be remembered using this mnemonic :
Primary malignancies responsible for hemorrhagic metastases (MR CT BB):
- M - melanoma
- R - renal cell carcinoma
- C - choriocarcinoma
- T - thyroid carcinoma, teratoma
