48-year old woman with idiopathic hypoparathyroidism. Anteroposterior (AP) radiograph of the pelvis shows mineralization of iliolumbar ligament (pink arrow), broad ossification at the lateral margin of acetabulum (white arrow), osseous proliferation and irregular bony excrescences above the acetabulum (arrowhead), and lesser and greater trochanters and ischial tuberosities (open arrows). Note the capsular calcification of the hip joint (black arrow) and internal fixator for the right femoral shaft fracture.

Enthesopathic changes were seen at the muscular insertions of lesser trochanter and greater trochanter, ischial tuberosities, and iliac crests, with normal sacroiliac joints (Fig. 1).
48-year old woman with idiopathic hypoparathyroidism. AP radiograph of the thoracolumbar spine shows ossification of interspinous ligament (open arrow) and syndesmophytes (white arrow). Note the ossification of iliolumbar ligament (black arrow).

AP radiography of the thoracolumbar spine revealed extensive ossification of the interspinous and supraspinous ligaments, and a syndesmophyte formation (Fig. 2).
48-year old woman with idiopathic hypoparathyroidism. Lateral radiograph of the cervical spine shows ossification of the anterior longitudinal ligament (open arrow) and irregular bony excrescences at the inferior margin of the spinous process (white arrow). Note a mild diffuse increase in the bone density.
