Malignant neoplasm of unspecified part of unspecified bronchus or lung [C34.90], Reason for Study: ^Reason: lung cancer, evaluate for brain mets History: recent fall and loss of conscious, headaches There is no evidence of acute ischemic or hemorrhagic lesion.There is about 12.5mm (AP) x 11.4mm (CC) x 9.4mm (RL) sized extra-axial enhancing mass attached on the right side of the proximal which shows low signal intensity on T2 weighted images, and isointense signal intensity on T1 weighted image suggest possible meningioma, unchanged since prior scan in terms of size and MR characteristics.There are bihemispheric scattered somewhat patchy T2/flair high signal intensity lesions on periventricular white matter and centrum semiovale indicate nonspecific small vessel ischemic disease, unchanged since prior scan.The ventricles, sulci and cisterns are unremarkable. There is no intra-axial mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. No evidence of acute ischemic or hemorrhagic lesion.2. No abnormal enhancement.3. Non specific small vessel ischemic disease.4. Unchanged right parafalcine extra axial enhancing lesion most likely represent a meningioma (about 11mm x 12mm) since prior scan.
