Brain lesions concerning for pancreatic cancer metastasis: work finding difficulties. There is a heterogeneously enhancing mass in the posterior left inferior frontal gyrus that measures up to 35 mm. There is a small amount of susceptibility effect within the tumor, which may represent blood products. There is extensive surrounding vasogenic edema with partial effacement of the left posterior lateral ventricle. However, there is minimal midline shift and no herniation. There is a lobulated lesion in the right parietal white matter that measures up to 12 mm with circumferential susceptibility effect and an associated developmental venous anomaly. There is also a punctate focus of susceptibility effect in the right pons, with corresponding calcification on the prior CT. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is a small left maxillary sinus retention cyst.
1. A lesion in the left inferior frontal gyrus that measures up to 35 mm likely represents a metastasis.2. A lesion in the right parietal white matter that measures up to 12 mm with circumferential susceptibility effect and an associated developmental venous anomaly likely represents a cavernous malformation.3. A punctate focus of susceptibility effect in the right pons may also represent a cavernous malformation.
