title: [The value of ultrasound in the diagnosis of thyroid diseases in Mauritania (171 cases)].
abstract: We investigated thyroid abnormality in Mauritania by carrying out a prospective ultrasound study of 171 patients. One hundred and thirty four patients underwent thyroid hormone determination (T3, T4 and TSH) and 123 had complementary plain film X rays of the chest and neck. These ultrasound examinations accounted for 3.8% of all ultrasound examinations performed over the study period. Thyroid abnormalities were more frequent in young adults aged 20 to 40 years (67.4%) and in women (83%) in Mauritania. Thyroid diseases affected people from savanna and mountain regions in particular. Diffuse goiters were the most frequent problem (76.3%) and most were multinodular or heterogeneous forms with necrosis or hemorrhage. One case of homogeneous diffuse goiter was found to be an infiltrating vesicular adenocarcinoma with metastatic adenopathy. Nodular goiters were mostly cystic, with septation (51.9%) and could be mistaken for hydatid cysts, which are endemic to the region. Further study of these aspects of thyroid diseases in Mauritania are required.
