Diagnosis: Malignant neoplasm of other parts of brainClinical question: h/o astrocytoma; now with possible progressionSigns and Symptoms: preop planning for biopsy The CSF spaces are appropriate for the patient's stated age with no midline shift. The patient is status-post right-sided parietal craniotomy for right right lobe surgery. There is heterogeneous but predominantly increased T2 signal at the surgical site associated with multiple foci of susceptibility and a patchy enhancement which is similar in extent and signal characteristics when compared to the prior exam. In general the right lateral ventricle is enlarged.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 are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.There is a right parietal lobe infiltrating mass present similar in extent when compared to the 6/22/2015 exam.2.Examination is performed for the purpose of imaging guidance during surgery.
