Abstract

Haemangiomas involving the internal auditory meatus (IAM) are rare and can mimic other frequent lesions of the IAM such as schwannomas by their clinical and imaging aspects. The case of a patient with an atypical IAM haemangioma fluctuating in size is reported to highlight this diagnostic possibility. A 36-year-old female presented with a sudden and recurrent left sensorineural hearing loss (SNHL). Three consecutive MRIs were performed in a 10-month period of preoperative observation. They showed a fluctuation of the tumour signal and size. The surgical removal was performed via a translabyrinthine approach. Pathological findings were consistent with the diagnosis of a heamangioma. MRI and CT findings suggested the diagnosis of IAM heamangioma, but the rapid variation in size and signal was misleading. This phenomenon may be due to haemorrhage or oedema, and can be accompanied by a deterioration of the hearing function. Early surgical resection is the treatment of choice and allows to confirm the diagnosis.
