Diagnosis: Other malformations of cerebral vessels Hemangioma of intracranial structures MyoclonusClinical question: Venous anomaly with telangiectasia, 6 month follow up; 3T Scanner, CCM ProtocolSigns and Symptoms: tremor, off balance, difficulty speaking The CSF spaces are appropriate for the patient's stated age with no midline shift. There is leptomeningeal enhancement along the surface of the right cerebellar hemisphere. There is a large developmental venous anomaly present extending into the right cerebellar hemisphere, midbrain and pons. There is a a 33mm x 57mm axial dimension patchy focus of the susceptibility effect and patchy contrast enhancement involving the pons, midbrain, right middle cerebellar peduncle and the right cerebellar hemisphere. There are multiple foci of punctate more profound signal loss within this area.No edema is identified within the brain parenchyma.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 are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.There is a large brainstem and right cerebellar lesion associated with a developmental venous anomaly which is suspected to represent capillary telangiectasia. There are multiple foci of suspected microhemorrhage within this.
