Post-radiotherapy radionecrosis of the temporal bone resulting in delayed CSF otorrhoea: a case report.
The authors report a case of temporal glioblastoma multiforme, who received post-operative radiotherapy. The patient presented to neurosurgery 8 months post-radiotherapy with CSF otorrhoea. This was shown to be from a defect of the right tegmen tympani secondary to radionecrosis of the petrous temporal bone. This was successfully repaired via craniotomy and repair of the middle cranial fossa floor. The authors have been unable to find previously published examples of isolated radio-necrosis of the temporal bone following radiotherapy for glioblastoma multiforme.
