El hiperparatiroidismo primario en la infancia es una enfermedad infrecuente, debida en la mayoría de los casos a adenomas. El proceso puede cursar de forma asintomática y su diagnóstico debe sospecharse por la detección de hipercalcemia en las pruebas analíticas habituales.

Se describe el caso de un varón de 13 años de edad con hipercalcemia en quien la primera manifestación de la enfermedad fue litiasis renal. La resonancia magnética (RM) cervical mostró un nódulo paratiroideo derecho de 13 × 8 × 5 mm. La gammagrafía con cardiolite-tecnecio 99 (99mTc) era indicativa de adenoma paratiroideo inferior derecho. Se realizó paratiroidectomía inferior derecha que descartó hiperplasia del resto de las paratiroides y presencia de tejido ectópico. El diagnóstico anatomopatológico fue de adenoma de paratiroides. Tras la intervención quirúrgica, las concentraciones de calcio se normalizaron.

En conclusión, ante un niño con hipercalcemia y con sospecha de hiperparatiroidismo primario por los datos del laboratorio, debe realizarse gammagrafía con cardiolite- 99mTc y RM cervical y, posteriormente, efectuar paratiroidectomía.

Primary hyperparathyroidism is an infrequent condition in infancy and is usually due to adenoma. It may be asymptomatic and is suspected when isolated hypercalcemia is detected in routine investigations. We describe the case of a 13-year-old boy with hypercalcemia presenting as renal lithiasis. Cervical magnetic resonance revealed a 13 × 8 × 5 mm-node in the right parathyroid. Gammagraphy with Cardiolite-Technetium 99 suggested an adenoma in the inferior right portion of the parathyroid. Right inferior parathyroidectomy was performed and ectopic tissue, as well as hyperplasia of the parathyroids, was removed. The histopathological diagnosis was adenoma of the parathyroid gland. After surgery blood calcium levels returned to normal. In conclusion, cervical magnetic resonance and gammography with Cardiolite-Technetium 99 should be performed in children presenting hypercalcemia and laboratory results suggestive of primary hyperparathyroidism. Subsequently, parathyroidectomy should be performed.
