History of metastatic head and neck cancer with single brain metastasis status post resection. Please evaluate for radiosurgery. A small surgical resection cavity is evident at the junction of the right temporal and occipital lobes. The cavity is mildly hemosiderin stained. The margins of the cavity demonstrate thin rim enhancement. At the upper margin of the cavity, however, an area of more nodular enhancement is seen with a small ring-enhancing component.No new enhancing lesions are seen. No evidence of edema or mass effect is detected. A small focus of susceptibility is demonstrated along the left temporal horn.
Limited sequences for treatment planning demonstrate a surgical resection cavity at the junction of the right temporal and occipital lobes. The margins of the cavity enhance thinly which may be postoperative, though there is an area of more nodular/ring enhancement along its superior margin which is nonspecific.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
