Brain Metastasis with High Protein Content- An Extremely Rare Imaging Feature

Metastasis represents the most common brain malignancy. Solitary or multiple ring enhancing intra-axial lesions bordered on the graywhite matter junction with disproportionate edema is the usual pattern on imaging. No reports of high protein content parenchymal metastatic lesion can be found in literature till now. Authors here describe a case of 42 year old female presenting with features of intracranial hypertension and imaging suggestive of a high protein containing lesion. Gross total resection was performed and histopathological features were suggestive of metastatic papillary adenocarcinoma.
