Figure. Computed tomographic, biopsy, and electron µgraph findings.A. Computed tomographic scan of patient 4's abdomen, showing diffusely hypodense liver compared with spleen of normal density. These findings are consistent with fatty infiltration. B. Liver biopsy specimen from patient 1 showing extensive microvesicular and macrovesicular hepatic steatosis (hematoxylineosin stain; magnification, x200). C. Frozen cross-section of skeletal muscle biopsy sample from patient 4, demonstrating abundant lipid droplets within the muscle fibers (oil red O stain; magnification, x400). D. Electron µgraph of skeletal muscle from patient 4, showing subsarcolemmal accumulation of lipids (magnification, x15 000).
