Diagnosis: Hemangioma of intracranial structuresClinical question: 3T Scanner, CCM Protocol/QSM/Permeability, yearly follow up s/p bleed in 2014Signs and Symptoms: Yearly surveillance CCM with prior hx of bleed There is redemonstration of a lesion within the left medulla associated with peripheral susceptibility effect and central T2 signal hyperintensity. It has not changed appreciably when compared the previous exam from 11/13/2014.There is a subcortical white matter punctate T2 and FLAIR signal hyperintense lesion in the right frontal lobe subcortical white matter and another similar lesion in the subcortical white matter along the anterior aspect of the right insular cortex. In isolation these are of little clinical significance. They were present on the 3/5/2001 exam.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 redemonstration and no change in the appearance of a hemorrhagic lesion suspected to represent a cerebral cavernous malformation located in the left half of the lower medulla. This was not clearly present in the 3/5/2001 exam
