Paraganglioma of the cerebellopontine angle : report of two cases

Paragangliomas of the cerebellopontine angle are exceptional tumours. We report two cases of paragangliomas of the cerebellopontine angle. To our knowledge, including these two cases, only five cases have been reported in the international literature. The emerging field of genetic study of these tumours will prove critical for their diagnosis and prognosis. The presence of paraganglioma in this area is explained by an abnormal embryologic migration of paraganglionic cells into the cerebellopontine angle, associated with tumorogenesis. These tumors can be associated with others cervico-facial tumours and to genomic abnormalities. The preoperative diagnosis of these tumours is very difficult, with clinical signs like hearing loss, vertigo and tinnitus are very ambiguous. Radiologic assessment of the cerebellopontine angle is also vague. The final diagnosis is only made possible peroperatively and by the post-operative histopathologic study. ENT and neurosurgeons should be awarded of the possible existence of paragangliomas of the cerebellopontine angle, and the necessity of a systemic and genetic assessment.
