Female, 57 years old, status post resection for cavernoma. Follow-up exam. Findings are seen compatible with left frontal craniotomy and resection of a portion of the left frontal lobe. The resection margin demonstrates a thin rim of diffusion restriction which likely reflects postoperative cytotoxic edema. The surgical cavity contains a mixture of CSF, blood product and debris. Parenchymal edema is evident in the surrounding tissues. The previously demonstrated cavernous malformation is not identified on this examination and has therefore likely been included within the resection. Elsewhere, a few scattered nonspecific foci of FLAIR hyperintensity are seen. No other areas of edema or mass effect are detected. Ventricular size and morphology remain within normal limits.
Expected post operative findings are seen compatible with resection of a left frontal cavernous malformation.
