Multiple calvarial doughnut lesions present a dramatic roentgenographic picture. The scant literature indicates that they are benign, asymptomatic, and of obscure etiology. Three additional examples of this rare entity have been identified all in the same family and are presented. The implication of a familial relationship with regard to develpmental pathogenesis is discussed. Histology is nonspecific but is felt to be consistent with hyperostosis.
多发性颅骨环形病变呈现出显著的X线影像学表现。少量文献表明它们是良性的、无症状的，且病因不明。已在同一家庭中发现了另外3例这种罕见病症的病例并予以呈现。本文讨论了家族关系在发育发病机制方面的意义。组织学表现不具有特异性，但被认为与骨质增生一致。
