Unusual lateral presentation of popliteal cyst: a case report.

The commonest cyst to occur in the popliteal region is the popliteal cyst and over the past years it has received much clinical attention. The commonest position of the popliteal cyst is in the posterosuperior aspect of the medial femoral condyle. The present case report describes a rare case of popliteal cyst, which was found on the postero-superior aspect of the lateral condyle of the femur. Interestingly, there are fewer reports of popliteal cysts occurring in the postero-superior aspect of the lateral condyle. We as anatomists describe the topographical anatomy of an unusual presentation of popliteal cyst in the postero-superior aspect of the lateral popliteal region and discuss its clinical significance. Anatomical knowledge of such anomalies may be important for clinicians, orthopedic surgeons and academicians in routine clinical practice.
