Slipped capital femoral epiphysis as primary presentation in an adolescent with primary hyperparathyroidism due to ectopic mediastinal parathyroid adenoma

Abstract

Key Clinical Message Ectopic mediastinal parathyroid adenoma causes primary hyperparathyroidism presenting as hypercalcemia. When children with hypercalcemia present with slipped capital femoral epiphysis, a detailed evaluation for hypercalcemia must be done before surgery. Abstract The association between slipped capital femoral epiphysis (SCFE) and hyperparathyroidism has been reported and is rare. Each is known to affect different age groups. We report a case of a 13‐year‐old boy with SCFE and primary HPT leading to hypercalcemia and skeletal deformities.
