Osteoma of the internal auditory canal
Summary Objective Osteoma occurs almost exclusively in the head and neck region, only rarely developing into the internal auditory canal. We report an incidental finding of a case in the radiological evaluation of a patient with left hemifacial spasm. Patients and methods A 79-year-old woman consult...

| description | Summary Objective Osteoma occurs almost exclusively in the head and neck region, only rarely developing into the internal auditory canal. We report an incidental finding of a case in the radiological evaluation of a patient with left hemifacial spasm. Patients and methods A 79-year-old woman consulted for left hemifacial spasm associated with left anacusis. Symptoms occurred up to 30 years prior to the first radiological investigations. Computed tomographic (CT) and magnetic resonance (MRI) images were taken. Results MRI demonstrated a left internal auditory canal lesion with spontaneous hypointense signal on T1- and T2-weighted images. CT showed the lesion as a typically dense and opaque osteoma. It measured 0.6 cm in maximum size. No surgery was performed because of the slow-growing features of the lesion. Clinical monitoring was recommended. Conclusion Osteomas are diagnosed incidentally in asymptomatic patients. Our case was symptomatic and raised the question of surgical management. This article discusses the presentation and management associated with this exceptional osteoma location. |
