1. Stigmata of intracranial hypertension, with marked papilledema, slitlike ventricles and small superior sagittal sinus and transverse
sinuses. Abnormal signal and enhancement in the right transverse/sigmoid sinus junction, could represent slow flow, thrombosis, or tumor, uncertain contribution to intracranial
hypertension. Superior sagittal sinus is not well seen, enhancement similar to that of dural based tumors, tumor infiltration is
difficult to exclude. Evaluation with CTA CTV may be useful as clinically indicated.
2. Progression of diffuse pachymeningeal enhancement with multiple areas of plaque-like thickening, right greater than left, concerning for progression of dural metastatic disease. Slight interval increase in left-sided subdural hygroma.
3. Multiple new microhemorrhages bilateral cerebral hemispheres. May be on the basis of intracranial hypertension and/or coagulopathy in the known from thrombocytopenia and DIC.
4. Subacute right cerebellar infarct.
5. Diffuse bone marrow signal abnormality, concerning for metastatic marrow replacement though component may be treatment related.
6. New complete opacification of the right frontal sinus, posterior ethmoid air cells, and sphenoid sinuses, likely congestive.
