'Kissing sequestra'--a forgotten manifestation of osteo-articular tuberculosis. A case report.
Osteo-articular tuberculosis may be difficult to diagnose radiologically. A male patient with pain in the left hip presented with radiological features of the disease--narrowing of the joint space, peri-articular osteopenia, subchondral erosions and cavity formation. In addition 'kissing sequestra' were present in the adjacent femoral head and acetabular joint surfaces. This radiological feature, described as common by Phemeister and Pomerantz in 1933, has been largely overlooked in recent literature. The presence of 'kissing sequestra' is a valuable diagnostic aid and should not be overlooked.
