Lung cancer. Headache. Evaluate for metastasis. There is no evidence of intracranial hemorrhage, mass, or acute infarct. Confluent and patchy T2/4 hyperintense signal is present in both cerebral hemispheres. There is mild expansion of the CSF-containing spaces, reflecting mild global parenchymal volume loss. The brain parenchyma and pituitary gland appear unremarkable otherwise. There is no abnormal intracranial enhancement. There is no midline shift or herniation. The major cerebral flow voids are preserved, accounting for hypoplastic left vertebral artery with PICA termination. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is mild scattered mucosal thickening in the paranasal sinuses relatively greater involving the left frontal sinus and left anterior ethmoid air cells.
1.No evidence of intracranial metastatic disease.2.Mild-to-moderate chronic small vessel ischemic disease.3.Mild mucosal thickening in the paranasal sinuses.
