Diagnosis: Secondary malignant neoplasm of brain and spinal cordClinical question: pre-op for tomorrowSigns and Symptoms: pre-op for tomorrow There is redemonstration of a 20 mm x 20 mm well-circumscribed enhancing mass located along the superior aspect of the left cerebellar hemisphere. There is redemonstration of a 16 x 19 mm axial dimension ring-enhancing lesion in the vermis. There is redemonstration of a 25 x 27 mm axial dimension ring-enhancing mass in the right cerebellar hemisphere centered in the inferior semilunar nodule. There is associated with vasogenic type edema with these cerebellar lesions. Overall compared to the prior exam there does not appear to be a significant interval change.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.Multiple cerebellar metastases appear stable compared to prior exam. Examination is performed for the purpose of stereotactic guidance during surgery.
