Three‐dimensional Reconstruction of Melanotic Neuroectodermal Tumor of Infancy Involving the Occipital Bone and Dura

A rare case of melanotic neuroectodermal tumor of infancy involving the right occipital bone in an 11‐month‐old infant is described. The bone tumor and its dural extension were surgically removed. Threedimensional reconstruction of the tumor and brain from neuroimaging data added worthwhile information for preoperative planning. Microscopic examination revealed melanotic and neuroblastic tissue in a fibrillary matrix involving the expanded bone and superficial dura. A focal osteoblastic cranial mass in an infant should alert the clinician to consider this tumor.
