Surface bone histology of the occipital bone in humans and chimpanzees [PDF]

The Anatomical Record Part B: the New Anatomist, 2005
AbstractHuman and chimpanzee occipital bones are thought to grow and develop in distinctly opposite bone remodeling patterns. Preliminary research examining growth‐remodeling fields (GRFs) from the surfaces of the occipital bone in modern humans and chimpanzee indicates this may not be entirely correct.

Aneurysmal bone cyst of the occipital bone: Case report

Surgical Neurology, 1993
A 21-year-old male with a painful, expanding mass in the occipital bone was operated on. The clinical findings were suggestive of a malignant tumor. However, appearance and histological examination of the operative specimen identified it as being an aneurysmal bone cyst, a rather rare nonneoplastic lesion of unknown origin. Besides demonstration of the
