(a, b) Plurilamellar periostitis (curved arrows) was shown on (a) a radiograph as focal lucent line (straight arrow) and on (b) a transverse CT scan as a low-attenuation line (straight arrow) at the bone-stem interface.

(a) Transverse CT scan at the joint level shows a nonfocal low-attenuation line (arrows) at the acetabular cement-bone interface. (b) Transverse CT scan of soft tissues shows joint distention (arrows).

Transverse CT scan with soft-tissue reconstruction algorithm shows joint distention (curved arrows) and focal areas of low attenuation in the muscle. Extension into the subcutaneous tissues to the skin was confirmed as an abscess (straight arrows) at surgery.

(a, b) Transverse CT scans of soft tissues show (a) distention (arrow) at the joint level and (b) hypoattenuating structure collection (arrows) in the quadriceps muscle.
