Magnetic resonance imaging differential diagnosis of brainstem lesions in children

Figure 4 Leigh’s syndrome in complex I deficiency. A 7-year-old girl with vomiting and respiratory distress. Axial T2-weighted images show multiple focal hyperintense lesions, involving midbrain, pons and medulla, mostly sparing the peripheral zone of the brainstem. A diffuse T2 hyperintensity and engulfement of the right basilar portion of the medulla is seen in G (white arrow): Differential diagnosis includes primary lesion and unilateral hypertrophic olivary degeneration.
