Intensity-Modulated Radiotherapy for a Rendu-Osler-Weber Disease Patient with Recurrent Severe Epistaxis: A Case Report

Figure 4

Endoscopy of the right nasal cavity following removal of the nasal dressing 2 weeks after the last radiotherapy showed a vast septal perforation due to multiple endonasal interventions. A 3 mm bluish spot at the dorso apical border of the septal perforation and very fine teleangiectatic vessels were the only possible and now inactive sites of the former extensive teleangiectatic lesions.
