MRI Report (6/20/13)

Examination: MRI BRAIN WO/W CONT Indication: WHO grade 2 astrocytoma in the left parietal region, status post gross total  resection.  Comparison: Most recent MRI from April 20, 2013  Technique: Non-contrast Head: Axial T1, axial T2, axial diffusion.  Post-contrast Head: 3D FLAIR (Sag, Ax, & Cor), axial diffusion. Axial, coronal & sagittal T1. Contrast: Contrast Agent Prohance 15 ml 07/20/2013 INTRAVENOUS Findings: Again identified stable changes related to left-sided craniotomy. The left  parietal lobe resection cavity is unchanged in appearance since the prior  exam. The prior described nonenlarged T2/FLAIR hyperintensities surrounding  the medial and anterior aspect of the inferior part of the resection cavity  (604/38 and 39) unchanged in appearance since the prior exam.  Hypointense signal involving the medulla on T2 appear to be artifacts. Postcontrast imaging demonstrates linear enhancement in the surgical cavity  underlying the craniotomy this is unchanged from the prior exam.  No nodular enhancement in the surgical bed. Small DVA in right frontal lobe. There is no acute infarction. No mass effect no hydrocephalus.  The major intracranial flow voids show expected appearance.  Bilateral paranasal sinuses and mastoid air cells are clear. Bilateral orbits  are normal. Impression: Compared to prior MRI from April 20, 2013, Stable appearance of resection  cavity in the left parietal lobe with nodular T2/FLAIR hyperintensities along  the anterior and medial aspect of the inferior part of the resection cavity.  Continued followup is recommended. No acute intracranial process.
