Hemangioma of intracranial structures [D18.02] / Heteronymous bilateral field defects [H53.47], Reason for Study: ^Reason: assess CCM resection pod#1 History: s/p CCM resection Motion artifact degraded image quality.Right pterional craniotomy status.Previously seen infero-mesial aspect of the lesion measured about 7.3mm x 7.3mm on coronal scan and 8.6mm x 7.2mm on axial scan has been resected on this scan.There is, however, residual part of the original cavernous malformation especially anterior and superior aspect. The size of the residual lesion is about 5.2mm x 6.2mm on coronal scan and 6.6mm x 5.4mm on axial scan. There are restricted diffusion lesions involving anterior aspect of the right temporal lobe and inferior aspect of the frontal lobe (inferior frontal gyrus and lateral orbital gyrus) indicating possible cytotoxic edema.There is minimal midline shift toward left side and the right lateral ventricle appears to be slightly effaced which are not unusual for postoperative status. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Postoperative status of the right inferior basal ganglia cavernous malformation.2. There is residual lesion on the superolateral aspect of the original lesion as described above.3. Possible cytotoxic edema on the right temporal lobe anterior aspect and inferoanterior aspect of the right frontal lobe as described above.
