Malignant neoplasm of bronchus and lung, unspecified site. Examination of participant in clinical trial The patient is status post right sided parietal craniotomy.There is gyriform susceptibility effect associated with T1 signal hyperintensity and contrast enhancement along the lateral aspect of the right post central gyrus. This is unchanged since the prior exam.There is a T2 and FLAIR hyperintense non enhancing left frontal periventricular and subcortical white matter lesion measuring 8x6 mm axial dimensions. It measures 4mm on the prior exam which was performed with different technique.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate minor scattered opacities in the ethmoid air cells. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.There is a hemorrhagic lesion in the right parietal lobe suspected to represent post surgical change. Please correlate with clinical treatment history. The possibility it represents post-radiation effect cannot be excluded. Continued surveillance would help assess for superimposed local recurrence. 2.There is a left frontal white matter lesion which is slightly larger on the current exam. It is non-specific. It is possible that this is treatment related.
