Male, 75 years old, with metastatic head and neck cancer to the brain status post SRS to a left cerebellar metastasis in 10/2014. Assess for brain metastases. A focus of susceptibility is redemonstrated within the left lateral cerebellum corresponding to the site of the previously treated metastasis. No suspicious enhancement or edema is detected at this location.A small focus of encephalomalacia within the right cerebellum is unchanged and may represent a tiny chronic infarct. No evidence of focal parenchymal edema, mass effect or pathologic enhancement is seen. Scattered foci of FLAIR hyperintensity are nonspecific and unchanged. Scattered punctate foci of susceptibility effect are also noted without significant change. No abnormal fluid collections are detected. The ventricles are normal in size and morphology. Post-treatment findings are noted including fatty atrophy of the right hemitongue. Chronic mucosal thickening and opacification the right maxillary sinus are redemonstrated.
1.The previously treated left cerebellar lesion is redemonstrated as a focus of susceptibility. No significant interval change is noted.2.No new or suspicious intracranial lesions are seen.
