Abstract:
Objective To evaluate the role of several imaging technology in the diagnosis of patients with mitochondrial encephalomyopathy.Methods Clinical and image findings of 11 cases of mitochondrial encephalomyopathy were retrospectively analyzed.9 patients were studied with MR,2 patients with MRA and DSA,3 patients with CT plain scan,and 1 patient with positron emission tomography (PET).Results CT and MR imaging showed multiple or migrating infarct-like lesions in 9 cases,mainly involving the posterior temporal and occipital regions which crossed vascular boundaries.Lesions were distributed in the temporo- occipital and parietal lobes in 7 cases,bilateral thalamus in 1 case,the brainstem,cerebellum,and the deep cerebral white matter in 1 case.Other lesions demonstrated as cerebellum atrophy in 1 case,syringomyelia in thoracic spinal cord in 1 case.PET showed the metabolic rate of glucose was elevated early in the acute phase and reduced in the recovery phase.Conclusion The examination combined with several imaging methods will help to improve the imaging diagnosis.
