Long-standing hypercalcemia in a 78-years old woman.

A 78 years-old woman was found with worsening hypercalcemia, osteopenia and memory loss during the past 2 years. Multiple, repeated imaging studies failed to reveal the etiology of the primary hyperparathyroidism. Bilateral neck exploration revealed a 4.5 × 2.3 cm right superior parathyroid adenoma in an ectopic position.
