77-year-old male status post fall. Question bleed question fracture. Review of prior studies indicates the patient has metastatic melanoma. Numerous brain masses are present. A prominent high attenuation mass in the high convexity of the right frontal lobe (series 6900 image 30) measures 1.1 x 0.9 cm. This lesion was not visualized on the MRI dated 3/2/2009. A high attenuation lesion in the right parietal lobe (series 6900 image 22) is also not clearly visualized on the previous MRI. Two high attenuation lesions in the right cerebellar hemisphere are faintly visible on post contrast images of the the study dated 3/2/2009. The large lesion seen in the left temporal lobe on the previous MRI is not well visualized on today's study.The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
1. No CT evidence of traumatic hemorrhage or fracture.2. Numerous high attenuation lesions scattered throughout the cerebral hemispheres and cerebellum -- consistent with hemorrhagic metastases from the patient's known melanoma.
