An electrocardiogram (ECG) is indicated. Imaging studies may include plain radiography or computed tomography (CT) scans. On radiographs, disorders associated with rickets or osteomalacia present with the pathognomonic Looser zones, which are better observed in the pubic ramus, upper femoral bone, and ribs. Radiography will also disclose osteoblastic metastases from certain tumors (eg, breast, prostate, lung), which can cause hypocalcemia. CT scans of the head may show basal ganglia calcification and extrapyramidal neurologic symptoms (in idiopathic hypoparathyroidism).
