 There are post surgical findings in the left frontal scalp region. Along the anterior margin of the resection cavity, there is a subcentimeter focus of enhancement with slight extension into a portion of the underlying calvarium. Other portions of the skin graft region posteriorly demonstrate diffuse enhancement. There are several supratentorial and infratentorial punctate foci of susceptibility effect, including within the left cerebellar hemisphere, without corresponding enhancement. There are mild areas of cerebral white matter T2 hyperintensity, which are unchanged. There is no evidence of acute infarction. The ventricles and sulci are unchanged. There is no midline shift or mass effect. There is a subcentimeter nodular focus in the left parotidectomy bed region, which does not appear to enhance centrally.
1. Postsurgical changes in the left frontal scalp with a subcentimeter focus of enhancing tissue along the anterior resection margin, which likely represents post-treatment effect, such as scar tissue.2. Multiple nonspecific foci of supratentorial and infratentorial punctate foci of susceptibility effect may represent hypertensive microhemorrhages, amyloid angiopathy, or perhaps less likely non-enhancing metastatic lesions.3. A subcentimeter nodular focus in the left parotidectomy bed region is nonspecific and may represent a post-operative fluid collection versus less likely tumor. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
