Osteomalacia: adults, bone formed during remodeling is undermineralized, causes osteopenia and fractures Hypophosphatemia: usually due to renal tubular defect, diuretics, hyperparathyroidism; rarely due to a vascular tumor Diagnosis. a. Several different disorders cause osteomalacia via mechanisms that result in hypocalcemia, hypophosphatemia, or direct inhibition of the mineralization process. Osteomalacia can present with following clinical features: Asymptomatic: Patients can be asymptomatic even with striking biochemical and densitometric findings of osteomalacia (eg: 29 year old women with severe vitamin D deficiency at 4 ng/ml, PTH at 100 pg/ml (range: 12-88) and low bone mineral density was evaluated for pathologic fracture.
