Skull base leiomyosarcoma metastasis manifesting itself as occipital condyle syndrome. A case report
The occipital condyle syndrome (OCS) is a rare and little-known neurological syndrome pathognomonic of metastatic involvement of the occipital condyle. OCS is the first significant sign of secondary involvement of the atlantooccipital joint in patients with a history of cancer. The early detection of skull base metastases permits timely use of radiation treatments and avoidance of surgical interventions.
