Abstract

Background and importance: HydroSet is a hydroxyapatite cement that can be used for reconstruction of skull defects. We describe a case of HydroSet resorption resulting in intraventricular and leptomeningeal deposition or calcification, which is a previously unreported complication. Clinical presentation: A patient who had a craniotomy augmented with HydroSet developed a pseudomeningocele, disappearance of cement fragments, and new hyperdense coating of the dura, upper cervical cord, and ventricles on CT after a fall. Conclusion: r Resorption of a hydroxyapatite cement resulting in leptomeningeal and ependymal deposition or calcification have not been previously reported.
