 Scintigraphic Findings:
Reagan was administered 160 millicuries of Technetium and multiple images were acquried. Areas of increased radiopharmaceutical uptake included:
-A focal intense uptake was noted in the glenoid region of the distal scapula of the left fore limb. Radiographs confirmed an osseous cyst like lesion that may have an articular component. The cyst like lesion was surrounded by extremely sclerotic bone. |
Impressions and Recommendations:
True subchondral bone cysts often occur in the middle of the glenoid cavity of the scalpula. Trauma is often an inciting cause. It is not an uncommon finding to have the degree of lameness vary between any given examination. True subchondral bone cysts are associated with active bone remodeling, therefore, scintigraphic evaluation can be useful in determining the extent of the pathology. Surgical debridement has been successfull in some cases. If the patient responds to intra articular therapy, a more conservative approach with intra articular medication may be an appropriate initial course of treatment. Other intra articular treatment options include platelet rich plasma or cultured stem cells as well as intra lesional corticosteriod therapy.
