Active calciphylaxis with right-sided weakness, right-sided vision changes and right-sided hearing loss evolving over last 6 hours. History of end stage renal disease. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is mild scattered cerebral white matter T2 hyperintensity. There is also a small area of encephalomalacia in the right cerebellar hemisphere. There is an enlarged partially-empty sella. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There is diffuse low T1 and T2 signal throughout the imaged bone marrow.
1. No evidence of intracranial hemorrhage, mass, or acute infarct. 2. Mild scattered cerebral white matter T2 hyperintensity is nonspecific, but may represent chronic small vessel ischemic disease versus early posterior reversible encephalopathy syndrome.3. Chronic right cerebellar hemisphere lacunar infarct. 4. An enlarged partially-empty sella is nonspecific, but can be a manifestation of pseudotumor cerebri. 5. Diffuse low T1 and T2 signal throughout the imaged bone marrow may be related to renal osteodystrophy.
