Tomografía computarizada de emisión monofotónica diagnóstica en diversas formas de presentación de encefalopatía de Hashimoto

We present the clinical features of five cases of Hashimoto's encephalopathy, all of which showed heterogeneous presentation and normal results on morphological tests except for cerebral single photon emission computed tomography (SPECT), which was decisive in the diagnosis. In addition, we present changes in brain SPECT images and their connection with the clinical and immunological parameters in the patient with the longest-standing Hashimoto's disease that we have seen.
