In this paper, the case of a 25-year-old male with metastasis of a PRG to the frontoparietal bone is described. CASE DESCRIPTION The patient presented with bulging on the left side of the head, headache, and weight loss. Magnetic resonance imaging (MRI) revealed a mass lesion in the left frontoparietal region that had destroyed both the external and internal table of the bone, extending under the skin and above the dura mater. After a frontoparietal craniotomy the tumor was removed totally. Histopathological examination revealed the "Zellballen," which are pathognomonic for a PRG. Systemic examination and radiological investigation revealed no primary tumor source. CONCLUSION Metastasis of a PRG to the calvarium is possible; radical removal of the tumor will provide a cure.eninfo:eu-repo/semantics/closedAccessBone MetastasisCranial MetastasisParagangliomaArticle10.1016/S0090-3019(99)00200-15316163106972342-s2.0-0033963006N/AWOS:000085420000024Q2
