CTICasesIncidental Ectopic Ossific Lesion ("Rocks of Bone") of Unknown Etiology
Imaging findings
An incidental finding on a radionuclide PET study performed for prostate cancer staging showed discrete, well-formed pieces resembling trabecular bone within the soft tissues, an appearance the presenter dubbed "rocks of bone." No definite etiology could be identified by the group.
Key takeaways
This is presented as an unexplained but presumed benign incidental finding: recognizable, discrete, bone-like foci with no clear underlying disease process identified. It was raised to the audience as an open case in case anyone has encountered a similar appearance or has an explanation (heterotopic bone formation and amyloid were floated as possibilities but not confirmed).
