Initial radiographs and CT scans were negative, but magnetic resonance imaging revealed extensive bone marrow oedema. Elevated serum CA 19-9 (3,581 kU\/L) initiated further investigation, which identified an iCCA with acetabular metastasis. This case reports a rare instance of acetabular metastases from a cholangiocarcinoma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Since medullary bone lesions may remain occult on plain radiographs and CT, physicians must look beyond negative imaging to avoid diagnostic delays.
