It is a respiratory tropism SARS COV 2 infection. In the emergency of the pandemic, in medical imaging, only computed tomography (CT) of the lungs was favored to assess lung lesions. In addition, many cases of post-COVID-19 cognitive disorders have been reported. As the curve dips and services restart correctly, other imaging techniques have been used to better explore the disease. The objective of this presentation is to illustrate the contribution of metabolic imaging in the exploration of post COVID-19 cognitive disorders and to discuss the pathophysiological mechanisms. Hypometabolism brain lesions are objective signs of functional impairment whose pathophysiological mechanism is not yet fully understood. Metabolic imaging with PET-SCAN is a suitable tool for exploring these disorders, both for the severity and extent of the lesions and for the topography of the brain damage.展开更多

It is associated with hypothyroidism and very rarely with hyperthyroidism. We report here the results of the exploration of a case of thyrotoxicosis occurring during treatment with lithium salts. This was a 16-year-old patient with ongoing lithium treatment for two and a half years who presented with a thyrotoxicosis syndrome without a context of iodine overload or an episode of anterior cervical pain that could suggest subacute thyroiditis or orthopathic sign. The assessment of the exploration of this patient reveals biological hyperthyroidism without anti-TSH receptor antibodies, a normal ultrasound, and white scintigraphy which makes it possible to evoke the diagnosis of subacute thyroiditis (absence of the context of iodine overload). Note the interest in a thyroid assessment before and during treatment with lithium salts. Moreover, scintigraphy occupies a place of choice in the exploration of hyperthyroidism, particularly in the context of normal thyroid ultrasound imaging.展开更多
