title: Is cribra orbitalia synonymous with anemia? Analysis and interpretation of cranial pathology in Sudan.
abstract: Cribra orbitalia is a porotic or sieve-like lesion in the bony orbital roof. Its cause has been the object of research and discussion since the end of the 19th century. Since about 1960, most scientists have started to agree on the hypothesis that the lesion is a result of hypertrophy of the red bone marrow, and therefore is proof of anemia. However, recent investigations showed that in some cases, the histologic bone structure does not support the diagnosis of anemia. The status of cribra orbitalia as an indicator then becomes uncertain. We carried out a histologic examination of thin-ground sections in polarized light to clarify the possible sources of orbital roof lesions in a Nubian population from Missiminia, northern Sudan (n = 333). In at least 56.5% of cribra orbitalia cases, there were no histologic features indicating changes due to anemia. Signs of other pathological conditions, such as inflammation or osteoporosis, as well as pseudopathological cases, were found.
