A rare case of thyrotoxic periodic paralysis revealing Graves' disease in a young Malian

AbstractSporadic thyrotoxic periodic paralysis (TPP) is a rare muscle disorder that manifests with abrupt muscle weakness and hypokalemia associated with hyperthyroidism. It is mostly reported in the Asian population, and rare in Caucasians. Only few cases have been reported in people with black ancestry. Here, we report a rare case of thyrotoxic periodic paralysis revealing Graves' disease in a young Malian. A 17-year-old man was admitted in the Neurology clinic with rapid proximal tetraplegia that started after strenuous physical activities at the school. Clinical examination confirmed the proximal weakness. In addition, he had bilateral ptosis, exophthalmia, and horizontal ophthalmoplegia. Laboratory testing showed normal serum potassium and creatinine, low calcium and TSH levels. However, CK, FT4, thyroid stimulating hormone antibody, and acetylcholine receptor antibody levels were high. In addition, electrocardiogram was normal while thyroid Doppler-ultrasound showed heterogeneous, hypoechogenic, hypertrophic, and hyper vascularized gland. Patient had completely recovered his limb weakness within the following hours with symptomatic treatment. The clinical findings were consistent with Graves' disease, and he was put on Neomercazole. He did not present another episode of paralysis after 4-years of follow up. This is a first case of thyrotoxic periodic paralysis reported in Mali and one of the rare cases in sub-Saharan Africa. Despite its scarcity, all patients with acute...
