From: Acetabular roof lesions in children: a descriptive study and literature review
a-f A 17.3-year-old male patient (case N). The X-ray and CT results show right iliac bone destruction, with partial absence of the acetabulum, a clear boundary, and a sclerotic margin (a, b). MRI shows slightly long T1 signals in the right acetabular roof (c). During the operation, the lesion was found to consist of caseous tissue (d), and the X-ray results show that the lesion was cleared (e). The X-ray (f) results show partial bone growth after 6 months (white arrows indicate the site of the lesion)
