– These lesions are composed of poorly mineralized osteoid matrix and are not true fractures or stress fractures.
– It appears as a thin, translucent band, about 2 mm in width, which runs perpendicular to the surface of the bone extending from the cortex inwards.
– They are oriented perpendicular to the long axis of the bone, and do not cross the entire bone.
– It represents insufficiency fractures through unmineralized osteoid in patients with osteomalacia.

– Common sites include axillary margins of the scapulae, ribs, pubic rami, proximal femurs, proximal ulnae and proximal humerus.

– Similar changes radiographically may be seen in Paget’s disease; however, they are only seen in involved bone and are not generalized.

In addition, the lines in Pagets occur on the convex side of the bone(tensile aspect) while in osteomalacia they occur on the concave side (compressive aspect).
The lines in Paget’s represent insufficiency fractures.

In HPS the pyloric channel appears “elongated”, because there is a failure in the relaxation of the pre-pyloric antrum.

Barium study is performed with the infant in the right anterior oblique position, to facilitate gastric emptying.

– Fluoroscopic observations include vigorous active peristalsis resembling a caterpillar and coming to an abrupt stop in the pyloric antrum, outlining the external thickened muscle as an extrinsic impression, termed the
@ Shoulder sign.

– The String Sign – appears when the channel is outlined by a string of contrast material

– The Double Track sign – appears when several linear tracts of contrast material are separated by the intervening mucosa.

– The Tit sign – appears when the luminal barium is transiently trapped between the peristaltic wave and the muscle.

USG signs:
1. The “cervix” sign: appearance of HPS on long-axis US images, resembling the uterine cervix.

2. The “donut” lesion : represents the sonolucent thickened muscle, located medial to the gallbladder and anterior to the kidney.
