Diagnosis: Neoplasm of unspecified nature of brainClinical question: h/o brain tumorSigns and Symptoms: preop planning for resection The CSF spaces are appropriate for the patient's stated age with no midline shift. There is thickening of the right parietal bone associated with an extra-axial mass which invades into the right parietal lobe. There is vasogenic edema present within the right parietal lobe. The extra-axial mass measures 33 x 19 mm axial dimensions is associated with some infiltration into the adjacent calvarium. There is some associated enhancement along the right parietal lobe measuring 16 x 11 mm axial dimensions.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 scattered opacities in the maxillary sinuses. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Examination is performed for the purpose of stereotactic guidance and an surgery and is therefore limited exam. There is a mass involving the right parietal calvarium right sided meninges and extending into the right parietal lobe which is associated with vasogenic edema. This has not changed significantly since the 6/29/2015 exam. Differential considerations include granulomatous lesion as well as neoplasm.
