 BRAIN: There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are no areas of abnormal parenchymal signal. There is no abnormal intracranial enhancement. 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 skull and scalp soft tissues are unremarkable. There is mild mucosal thickening within the maxillary and ethmoid sinuses as well as mild fluid within the right mastoid air cells. There is a small focus of T2 hyperintensity within the midline nasopharyngeal soft tissues that is decreased in size compared with the prior exam and may represent a Tornwaldt or retention cyst.LUMBAR SPINE: The vertebral column alignment is within normal limits. The vertebral body heights are preserved. The vertebral bone marrow signal is unremarkable. The spinal cord displays normal signal and morphology. There is no evidence of intraspinal mass or abnormal enhancement. The paravertebral soft tissues are unremarkable. There mild degenerative changes throughout the lumbar spine with mild facet arthropathy and borderline ligamentum flavum thickening. In addition, there is disc desiccation and mild disc height loss at L5-S1 with a very mild disc bulge asymmetric to the left. There is no significant spinal canal or neural foramen stenosis at any level.
1. No evidence of intracranial or lumbar spine metastasis. 2. Evidence of acute sinusitis and non-specific right mastoid air cell fluid. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
