Left brain stem cavernous malformation: surveillance. The lesion with extensive susceptibility effect within the left aspect of the pontomedullary junction has not significantly changed, measuring approximately 5 mm in diameter. There is no evidence of associated developmental venous anomaly or surrounding edema. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
No significant interval change in the cavernous malformation within the left aspect of the pontomedullary junction.
