Left hemisphere intracerebral hemorrhages studied by (F-18)-fluorodeoxyglucose PET

E. Jeffrey Metter, MD, Catherine Jackson, MA, Daniel Kempler, PhD, Walter H. Riege, PhD, Wayne R. Hanson, PhD, John C. Mazziotta, MD, PhD and Michael E. Phelps, PhD

Veterans Administration Medical Center (Drs. Metter, Kempler, Riege, and Hanson), Sepulveda, CA; and the Department of Neurology (Drs. Metter and Mazziotta), the Division of Nuclear Medicine and Biophysics (Drs. Kempler, Mazziotta, Phelps, and Ms. Jackson), and the Laboratory of Nuclear Medicine (Drs. Metter, Riege, Mazziotta, and Phelps), School of Medicine, University of California, Los Angeles, CA.

We used PET to study patients with intracerebral hemorrhages in the left hemisphere. Three anatomic and physiologic patterns were observed. Patients 1 and 2 had midputamen hemorrhages with diffuse left < right hemispheric metabolic asymmetry most prominent in temporal and parietal regions. Patients 3 and 4 had posterior putamen-insula-temporal hemorrhages with left < right metabolic asymmetry in temporoparietal cortex and thalamus. Patients 5, 6, and 7 had smaller posterior hemorrhages. Left cortical metabolism was little affected in these three cases. Persistent aphasia was associated with severe metabolic left < right asymmetry in posterior middle temporal regions.

Funded in part by Department of Energy Contract # DE-AM03–76-SS00012 and US Public Health Service Research Grants R01-GM-24839 and P01-NS-15654. Dr. Mazziotta is the recipient of Teacher Investigator award 1K07-NS-0058804 from NINCDS.

Presented in part at the thirty-seventh annual meeting of the American Academy of Neurology, Dallas, TX, April 1985.

Accepted for publication January 8, 1986.
