Abstract:
Objective To investigate the etiological, clinical and neuroimaging features of symmetric corpus callosum lesions. Methods The clinical data of 27 patients with symmetric corpus callosum lesions were analyzed including the etiological, clinical and neuroimaging data retrospectively. Results In 27 patients, 16 patients suffered from chronic alcoholic encephalopathy, 5 patients suffered from viral encephalitis, 2 patients suffered from disturbance of water and electrolyte, 1 patient suffered from acute disseminated encephalomyelitis(ADEM), 2 patients suffered from brain trauma, and the etiology of 1 patient was unknown. Clinical manifestation: 8 patients had conscious disturbance, 5 patients had psychological and behavior disorder, 5 patients had epileptic seizure, 4 patients had ataxia, 3 patients had dysarthria and 2 patients had headache. There were abnormalities in CT scans and MRI. Manifestations in CT scans were symmetric low-density focus with clear boundary in corpus callosum. The performance in MRI was low-signals on T1WI but high signals on T2WI and DWI images, and there might be other intracranial lesions. In the follow-up period, foci disappeared in 15 patients, and foci persisted in 7 patients. Four patients lost in follow-up periods, and 1 patient was not followed up because of death. Conclusions The causes of symmetric corpus callosum lesions include chronic alcoholic encephalopathy, infections, disturbance of water and electrolyte and demyelination. And in some patients the cause is unknown up to now. The etiological treatment and symptomatic treatment are the common treating ways in clinic.
