[Ectopic thyroid: two cases]. / L'ectopie thyroïdienne: à propos de deux cas.

Ectopic thyroid is a rare condition (1/4000 to 1/8000 among patients with hypothyroidism). The underlying etiological pathogenic mechanisms remain unknown. Diagnosis is established on the basis of imaging findings. We report two cases of hypothyroidism in adult females who had ectopic sublingual thyroid glands. The first patient was a 20-Year-old woman who had been treated for hypothyroidism since the age of 13 Years before the diagnosis of ectopic thyroid 7 Years later. In both patients, the thyroid gland was palpable. In the first patient the physical examination revealed an ectopic sublingual gland. Scintigraphy confirmed the diagnosis in both patients. The CT-scan and MRI were positive in the second patient. Hormonal substitution therapy using L-thyroixine was given.

[Central diabetes insipidus with Behçet disease. A case report]. / Diabète insipide central en rapport avec une maladie de Behçet. A propos d'un cas.

Vasculitis with central diabetes insipidus is a rare condition which must be recognized for an appropriate management. We report a case of Behçet disease with central diabetes insipidus. A forty seven year old men presented recurring oral and genital ulcers, skin lesions, polyarthralgia. Two years later, he showed right uveitis and central diabetes insipidus without dysfunction of the pituitary gland. Computed tomographic scan showed normal neurohypophysis and pituitary gland. Later on, he presented hemiplegia. The cerebral computed tomographic scan showed hypodense lesions. Central diabetes insipidus should not be systematically searched because it is a rare feature of the Behçet disease.
