Skull metastasis from ampulla of Vater adenocarcinoma: case report.

We report a rare case of skull metastasis from ampulla of Vater adenocarcinoma in a patient with controlled primary neoplasm. This 65-year-old Korean man presented with headache and painful parietal scalp swelling, but he did not show any neurological deficits. Computed tomography revealed an osteolytic mass that invaded and expanded through the skull tables in full-thickness. On magnetic resonance images following Gadolinium injection, the mass appeared slightly hypointense signal on all sequences and intense heterogeneous enhancement. He underwent surgical excision with artificial grafting of calvaria and dura. Postoperative radiation therapy was ensued for metastatic adenocarcinoma, and he was well for the follow-up period of 3 months. To the best of our knowledge, this is the first such case that involved the skull.
