  • Image stack position: 59/88
  • Plane projection: Coronal
  • Aux modality: T1
  • Study findings: Mild left parietal atrophy without overt mesial temporal lobe atrophy. No other lobar atrophy. Bilateral cerebellar tonsillar herniation below the foramen Magnum, measuring up to 11 mm, with associated mild crowding at foramen Magnum. No hydrocephalus and no compression of the cervicomedullary region. No significant small vessel ischemic change and no evidence of previous cortical infarction nor intracranial hemorrhage. No overt regional hypoperfusion in ASL sequence. Conclusion: Mild left parietal atrophy, correlating with relative hypoperfusion in this region on SPECT. No significant vascular disease. Incidental Chiari 1 malformation.
  • Modality: MRI
  • System: Central Nervous System
  • Findings: RADIOPHARMACEUTICAL: 99mTc HMPAO, 781 MBq SPECT studies of the brain were performed. Mild to moderate severity hypoperfusion is seen in the parietal (left > right), posterior left temporal cortex and posterior cingulate, with preservation of the sensorimotor cortex. Brainstem, basal ganglia and cerebellar perfusion are normal.
