Diagnosis: Other specified counseling. Neoplasm of unspecified behavior of unspecified siteClinical question: Patient has MRI compatible pacemaker. Will see Device Clinic. Preop planning for brain biopsy. Signs and Symptoms: preop planning The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a 73 x 53 mm axial dimension mass involving right basal ganglia and adjacent right frontal lobe which extends to involve gray and white matter of the insular cortex and right orbital gyrus and right inferior frontal gyrus does not display any contrast enhancement.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 a mucous retention cyst in the right maxillary sinus and mucosal thickening elsewhere in the paranasal sinuses. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
There is a mass involving right frontal lobe, insular cortex and basal ganglia. Most likely this represents a primary brain tumor such as an oligodendroglioma. Please note this examination is a limited exam for the purposes of stereotactic guidance.
