New insights into central nervous system involvement in FOP: Case report and review of the literature

Research output: Contribution to journalArticle


Fibrodyspasia ossificans progressiva is an autosomal dominant disease due to activating mutations in activin receptor type IA and characterized by progressive heterotopic ossification. Recently, the same non-synonymous heterozygous somatic mutations of ACVR1 have been identified in brain biopsies or autopsy of 24-27% of patients with a rare cerebral tumor, the diffuse intrinsic pontine glioma. We report the first case of a patient with FOP with incidental findings of an abnormal soft tissue mass surrounding the brainstem and causing obstructive hydrocephalus, associated with bilateral dentate lesions. Clinico-radiological course during 10 years of follow-up was consistent with a benign lesion, excluding an oncogenic role of ACVR1 mutations.
