Objectives:
To describethe occurrence of a cavernous hemangioma of the external auditory meatus extending to the middle ear and the retroauricolar region in an adult patient, and to review the relevant literature.
Methods:
Case report. We report the clinical presentation, imaging studies and surgical procedures used in the study.
Results:
The angiographic study showed that the blood supply of the mass originated from the posterior auricular artery. Via a retroauricular approach, this artery was isolated and ligated in order to control the intra-operative bleeding. A canal wall up mastoidectomy with posterior tympanotomy and a tympano-canaloplasty were performed, permitting a complete excision. At 36 months of follow-up, no clinical and radiological signs of recurrence were detected.
Conclusion:
Surgical removal is the treatment of choice, with rare recurrence of the hemangiomas. Pre-operative evaluation is based on computed tomography (CT scan), but should be followed by magnetic resonance angiography (MR-angio) or intra-arterial digital subtraction angiography (IA-DSA), especially in case of wider lesions.
