Fibrous Capsule with areas of granulation tissue, multinucleated giant cells, areas of necrosis, and hemorrhage with clot c/w pseudoaneurysm
inversion recovery (TR 2000 / TE 18 /
TI 150) image shows a large ovoid mass
within the popliteal fossa, which is predominantly
of high signal intensity. There is no
edema in the adjacent muscles.
gradient echo (TR 500/TE 16/flip angle
30°) image shows multiple low-signal foci
within the mass consistent with calcifications.
Note also the mass merging with the
massively dilated popliteal vein behind the
distal femur (arrows). The uniform high
signal within the dilated vein is typical of
slow venous flow.
C Axial T2-weighted
(TR 2000/TE 80) image shows intimate relationship
of the mass to the popliteal artery
and vein (arrow), interposed between the
mass and the tibial plateau, although no direct
communication could be identified

Fig. 2A, B Digital subtraction angiogram of the left leg. A Arterial phase oblique image of the popliteal artery demonstrates a direct communication between the lumen of the artery and the mass (arrow), consistent with a pseudoaneurysm. B Late venous phase image shows large slow-flow venous channels (arrowheads) within the mass, draining into the enlarged popliteal vein (arrows)
4-25-04 HHR Converted to TSA
6-23-04 Glenoid component dislocated
5-12-04 Glenoid component well located
- indications are controversial;
- this needs to be performed prior to insertion of the humeral component;
- increased glenoid loosening rates from eccentric loading & excessive glenoid wear can be expected with w/ rotator cuff arthropathy
- radiolucencies around the glenoid component will eventually be seen in 60% of patients;
- some authors note that in many cases radiographs may fail to show loosening because the radiographic beam is not perpendicular to the bone-component interface;

“revision of a failed HHR to a TSA is a salvage procedure whose results are inferior to those of primary TSA…”
