65 years, Female, stage III B lung cancer. Evaluate for brain metastasis. Mild headaches.. No evidence of metastatic disease. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Few scattered foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with mild chronic small vessel ischemic changes. Brain parenchyma is otherwise unremarkable for age. No abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. There is nonspecific heterogeneity of the bone marrow particularly at the central skull base with a small focus of enhancement involving the upper aspect of the clivus. No frank destructive osseous lesions are appreciated.
1. No evidence of intracranial metastatic disease.2. Nonspecific heterogeneity of the bone marrow particularly at the central skull base with a small focus of enhancement involving the upper aspect of the clivus. These findings are nonspecific. No frank destructive osseous lesions are appreciated. Would suggest correlation with recent bone scan or PET to better assess for osseous metastatic disease.
