Status post right CCM resection Non-infused CT of brain:Examination demonstrate a foci of increased density measuring approximately 30 x 14.6-mm in trans-axial dimensions in the right basal ganglia. There are no prior CT examination for comparison. This finding is believed to represent patient's known cavernous malformation at this site. There is evidence of surgery and with extension of surgical tract to the right lateral aspect of this lesion. Although the above finding could represent patient's known cavernoma and does not particular area appeared like acute hemorrhage possibly itself subtle associated hemorrhage cannot be ruled out. The configuration of right frontal horn is identical to prior MRI exam which demonstrated extension of tumor into the right caudate nucleus and bulge into the right frontal horn.Postoperative changes of a right anterior frontal craniotomy and resultant air within the anterior cranial fossa bilaterally and minimal epidural collection under the craniotomy flap. There is no evidence of subarachnoid hemorrhage or definitive acute parenchymal hemorrhage. Ventricular system remains within normal size and unchanged since prior exam. There is no midline shift.
1.Postoperative changes of right frontal craniotomy for partial resection of right basal ganglial cavernoma.2.High density material within the right basal ganglia as measured could represent residual cavernoma. No definite postoperative hemorrhage is detected however high density of the mass can obscure small amount of hemorrhage.3.There is no evidence of hydrocephalus or midline shift.4.Residual air and minimal epidural hemorrhage under the craniotomy flap.
