Table 5 a Patterns of changes in size in focal abnormal signal intensities (FASI) on brain MRI over time in patients with NF1 across different brain regions are displayed in each patient. Patients with more (light gray) and most (dark gray) incongruent patterns across different brain locations are highlighted

From: Cerebellar radiological abnormalities in children with neurofibromatosis type 1: part 2 - a neuroimaging natural history study with clinical correlations

  1. aPattern types:
  2. A: FASI has remained stable in size or has decreased in size before stabilizing again
  3. B: FASI has been increasing in size or a new FASI has developed, which eventually either got smaller, stabilized or disappeared. FASI may have been preceded by a period of stability in size or a decrease in size before the enlargement occurred
  4. C: FASI has been getting smaller in size or has disappeared
  5. D: FASI has been increasing in size or a new FASI has developed. These changes may have been preceded by a period of stability in size or a decrease in size before the enlargement occurred
