60-year-old male patient with history of right pontine cavernoma. The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a mass redemonstrated the the right paracentric pons which has changed imaging characteristics when compared to the prior exam. There is interval decrease in central T2 signal hyperintensity with increased susceptibility effect centrally. The lesion is stable in size and currently measures 8 x 10 mm on T2-weighted imaging. It measures 8 x 10 mm on T2 weighted imaging. The lesion extends from the level of the superior cerebellar peduncle down to the pontomedullary junction.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 mucosal thickening in the maxillary sinuses, right greater than left, unchanged. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
Right pontine cavernoma is stable in size with interval increasing susceptibility artifact centrally.
