Osteomalacia LSBU

Description: Radiology case 448-571 Clinical presentation: 29 year old female, from India, vegitarian. Back and hip pain, muscle weakness.
The are symmetrical linear defects in the superior rami of the pubis. The ischio-pubic synostoses are low density, widened and the bones are not aligned (in a 29 year old whose bones should be fused! ). There is abnormal 'lucency' separating the apophyses of the iliac crests. The other symmetrical lucency in the pelvis is so gross that it is difficult to see. No normal sacro-iliac joint lucency would extend into the ilium at 45 degrees. The most visible lateral lucent line is in-fact diagnostic of this pathology. There is loss of trabecular detail and coarsening of the pattern, but the abnormality cannot be fully demonstrated on these images.
