Parkinson's disease with tremor. Preoperative planning MRI. There is an anterior left frontal lobe developmental venous anomaly. There is a punctate focus of high signal on the post-contrast T1-weighted image with associated susceptibility effect in the inferior left pons. There is mild scattered cerebral white matter T2 hyperintensity. There is mild diffuse cerebral volume loss. There is no midline shift or herniation. The major cerebral flow voids are intact. There is fluid within the right sphenoid sinus. The skull and scalp soft tissues are grossly unremarkable. There is a right lens implant. There is a large retrodental pannus with compression of the upper spinal cord. There is apparent fluid within the inferior left mastoid air cells.
1. Mild scattered cerebral white matter T2 hyperintensity is nonspecific, but may represent small vessel ischemia.2. A punctate focus of high signal on the post-contrast T1-weighted image in the inferior left pons may represent a telangiectasia, for example. 3. Anterior left frontal lobe developmental venous anomaly.4. Large retrodental pannus with compression of the upper spinal cord. 5. Fluid within the right sphenoid sinus may represent acute sinusitis.
