Secondary malignant neoplasm of unspecified site [C79.9] / Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: hx of metastatic melanoma with know brain mets s/p WBRT History: as above Previously seen multifocal various sized supra and infra tentorial enhancing lesions are again seen but with significant size reduction since prior scan. For example, the right frontal middle frontal gyrus lesion was 13.5mm x 9.2mm, now 7.4mm x 3.5mm; the left inferior frontal gyrus par opercularis lesions was 17.1mm x 18mm, now 10.4mm x 13.5mm.There is no new enhancing lesion seen on this scan. The ventricles, sulci and cisterns are symmetric and unremarkable. There is no midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Overall interval decrease in size of multiple enhancing metastatic lesions as described above.2. There is no evidence of new enhancing lesion on this scan.
