Osseous cyst-like lesion. Three-dimensional volume-reconstructed model (a) and sagittal CT slices from the right scapula of piglet 11 at the 1^st(a, b), 3^rd(c) and 4^th(d) examination intervals. (a) There is a radiolucent defect in the centre of the weight-bearing surface of the glenoid (between arrows). (b) At the 1^st interval the defect is located within the ossification front (at intersection of solid green lines). (c) By the 3^rd interval the defect has become surrounded by bone and is compatible with diagnosis of an osseous cyst-like lesion. (d) At the 4^th interval the defect has become filled with mineral/bone opacity and has resolved.
