[Spontaneous osteonecrosis of the iliac crest. Description of a formerly unverified location]

In a 27-years old male a radiographically well defined and compact area with some lucent sections was found incidentally at the top of the left iliac crest. The resection and the following histomorphologic examination of this tissue brought the diagnosis: spontaneous osteonecrosis of the iliac crest. To our knowledge this is the first time that the iliac crest has been proved as a localisation of the spontaneous osteonecrosis by histomorphologic examination.
