Primary hyperparathyroidism: a rare cause of genu varum deformity in adolescence

Dr. Pritesh Gaonkar, Dr. Pandharinath Audi, Dr. Mervyn Correia

Abstract :

Primary hyperparathyroidism is a rare condition in children and results from excessive secretion of parathyroid hormone. The most common cause being a parathyroid adenoma. The presence of limb deformity is atypical with very few cases of genu valgum being described in literature in association with hyperparathyroidism.We present a case of 15year old girl with bilateral genu varum deformity. Patient had hypercalcemia, hypophosphtemia, raised alkaline phosphatase and parathormones with normal renal and thyroid functions. Neck ultrasound done revealed a left inferior parathyroid nodule, skeletal survey showed subperiosteal resorption and osteopenia and MIBI with bone scan confirmed the diagnosis of left inferior parathyroid adenoma. Patient underwent left inferior parathyroidectomy. Following surgery her biochemical parameters including parathormone levels became normal with an initial episode of hypocalcemia(managed with intravenous and oral calcium)in the postoperative period.Bone pain decreased,though the deformity persisted.
