title: Clinics in diagnostic imaging (112). Perinatal lethal hypophosphatasia (PLH).
abstract: A two-hour-old female infant presented with respiratory distress and short limbs. Neonatal radiographs showed micromelic dwarfism and generalised demineralisation, especially at the ribs, long bones of both forearms and both fibulae. The spine showed a flattened shape. All long bones showed metaphyseal irregularities and flaring. Normal serum calcium and elevated serum phosphorus were found, while serum alkaline phosphatase was markedly reduced. A diagnosis of perinatal lethal hypophosphatasia was made. The aetiology, clinical manifestations, radiographical findings, laboratory assays, prenatal diagnosis and treatment of hypophosphatasia are discussed.
