%0 Journal Article %T Interparietal (Inca) bone: a case report %A Udupi S %A Srinivasan JK %J International Journal of Anatomical Variations %D 2011 %I International Journal of Anatomical Variations %X The squamous part of occipital bone consists of two parts, supraoccipital and interparietal. The interparietal portion ossifies intramembranously and in rare cases may be separated from the supraoccipital part by a suture. It is then called as the interparietal or Inca bone. The occurrence of Inca variable is rare in humans. The authors here report a case of true interparietal or Inca bone in adult human skull. Knowledge of Inca ossicles in human skulls may be useful to neurosurgeons orthopedic surgeons, anthropologists, radiologists and forensic experts. %K interparietal bone %K supraoccipital bone %K occipital bone %K intramembranous ossification %K Inca bone %U http://www.ijav.org/2011/ijav_2011_090-092.pdf
