[MRI findings delay the diagnosis of nasopharyngeal carcinoma]

This report concerns a 55-year-old female patient who presented with headache, dry right eye and dry nose on the right side. After 5 months magnetic resonance imaging (MRI) was carried out but no pathological findings were diagnosed. Right-sided facial pain appeared 6 months later and a second MRI was carried out but only fluid retention in the right mastoid was diagnosed. After a further 8 months paresis of the right abducent nerve occurred and a computed tomography (CT) scan of the petrous bone showed extensive destruction of the apex of the petrous pyramid. Subsequently a third MRI revealed a tumor of about 5 cm in diameter in the right pterygopalatine fossa which was also retrospectively visible in the first MRI with a size of approximately 3 cm and in the second MRI with 4 cm in diameter. The histological examination after biopsy resulted in the diagnosis of a nasopharyngeal carcinoma and radiochemotherapy was initiated. The patient died 9 months later. The relatives of the patient applied to the arbitration board for medical liability which requested expert opinions in neuroradiology and otorhinolaryngology. The board came to the conclusion that the claims for damages against the radiologist who had made the three MRIs were well-founded and recommended an extrajudicial settlement.
