EnglishIn a short girl with celiac disease and Hashimoto's thyroiditis (HT), the suspect of an associated pituitary lesion was suggested by the finding of a thyroid function pattern that was not compatible with HTrelated hypothyroidism (low FT4 with normal TSH). This case report reinforces the view that the finding of a normal TSH in presence of a low FT4 should always alert pediatricians and raise the suspect of central hypothyroidism, even when a primary thyroid disease has been already identified. In this case TSH deficiency played a critical role in disclosing diagnosis of craniopharyngioma (CP). Therefore, the subsequent workup was directed towards investigating pituitary function and morphology. Endocrinological investigations evidenced a picture of TSH and other pituitary hormone deficiency, whereas magnetic resonance imaging revealed an intrasellar CP. Therefore, in this case TSH deficiency played a key-role in disclosing CP diagnosis. Conclusions: the finding of a normal TSH in presence of a low FT4 should always alert pediatricians and raise the suspect of CH, even when a primary thyroid disease has been already identified.

| Abstract: | In a short girl with celiac disease and Hashimoto's thyroiditis (HT), the suspect of an associated pituitary lesion was suggested by the finding of a thyroid function pattern that was not compatible with HTrelated hypothyroidism (low FT4 with normal TSH). This case report reinforces the view that the finding of a normal TSH in presence of a low FT4 should always alert pediatricians and raise the suspect of central hypothyroidism, even when a primary thyroid disease has been already identified. In this case TSH deficiency played a critical role in disclosing diagnosis of craniopharyngioma (CP). Therefore, the subsequent workup was directed towards investigating pituitary function and morphology. Endocrinological investigations evidenced a picture of TSH and other pituitary hormone deficiency, whereas magnetic resonance imaging revealed an intrasellar CP. Therefore, in this case TSH deficiency played a key-role in disclosing CP diagnosis. Conclusions: the finding of a normal TSH in presence of a low FT4 should always alert pediatricians and raise the suspect of CH, even when a primary thyroid disease has been already identified. |
