Ewing's sarcoma in the occipital bone. Case report.

The head is a very rare primary site for Ewing's sarcoma which occurs most often in the long bones of the extremities and in the pelvis. This report describes an unusual case of Ewing's sarcoma arising from the occipital bone in a seven year old girl. The tumour compressed the venous sinuses, thus lowering the intracranial pressure resulted in temporary recovery which made the diagnosis difficult.
