Female, 65 years old, with history of lung cancer. A T2 hyperintense, partially FLAIR suppressing and presumably cystic lesion is identified within the right occipital lobe measuring 14 x 14 mm. There may be a small internal nodular component along the inferior aspect of the cyst versus a layer of debris. This lesion induces very mild edema in the adjacent parenchyma, but no significant mass effect.Numerous focal and patchy T2 hyperintense lesions are identified in the peri-ventricular and subcortical white matter of the cerebral hemispheres, a non specific findings which may reflect chronic microvascular ischemic disease or demyelinating disease among other possibilities. No restricted diffusion or other areas of edema are suspected.No acute intracranial hemorrhage is seen. The ventricular system is normal in size and morphology.An 18-mm region of T1/T2 hypointense marrow replacement is seen within the right parietal bone. Elsewhere, marrow signal characteristics are unremarkable.
1.A cystic or perhaps cystic and solid lesion is evident in the right occipital lobe. Given the stated history, this is concerning for metastatic disease.2.No definite additional metastases are suspected. However, postcontrast imaging is recommended, both to better assess the above lesion and to provide a more sensitive evaluation for additional small lesions.3.An area of marrow replacement within the right parietal bone is nonspecific and may simply represent sclerosis. This lesion would benefit from assessment with postcontrast imaging or CT imaging.
