Malignant neoplasm of unspecified part of unspecified bronchus or lung [C34.90], Reason for Study: ^Reason: Extensive stage SCLC, evaluation for intracranial metastases History: None There is no evidence of acute ischemic lesion.There is a focal susceptibility lesion on the right temporal lobe posterior aspect of middle temporal gyrus (series 42, image 13) which likely represent parenchymal mineralization, unchanged, otherwise no evidence of hemorrhagic lesion on the scan.A couple of scattered T2/flair high signal intensity on white matter is nonspecific but could represent nonspecific small vessel ischemic lesions.No evidence of abnormal enhancement.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no 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 metastatic lesion.2. No evidence of acute ischemic or hemorrhagic lesion.3. Unchanged right posterior aspect of the temporal lobe susceptibility lesion, left frontal lobe developmental venous anomaly and few nonspecific T2/FLAIR high signal intensity lesions since prior scan.
