Patient 1. A boy with trigonocephaly and mild developmental delay. Preoperative and postoperative MR studies were performed at the age of two years ten months (a, b) and three years eight months (c), respectively. A preoperative T1-weighted axial image shows symmetrical narrowing of the frontal region (a). Color ΔADC maps derived from the images obtained before (b) and after (c) the operation show the changes of the ΔADC in frontal lobes. Postoperative ΔADC values changed from 0.11 ± 0.021 to 0.16 ± 0.017 × 10–3 mm2/s.
