Diagnosis: Unspecified condition of brain Other convulsions Congenital anomaly of cerebrovascular systemClinical question: cerebral cavernous malformation, MRI presurgical for image guidance during surgerySigns and Symptoms: Surgery, STEALTH for presurgical planning for surgeryComments: The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a 32 x 21 mm axial dimension lesion in the left temporal lobe which has low signal periphery and heterogeneous central portion on T2-weighted imaging which has not changed substantially when compared to the previous examsNormal 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.Findings are compatible with a cavernoma located in the left temporal lobe.2.Please note that this examination was performed through purpose of stereotactic guidance for surgery and is therefore a limited exam.
