Both trigeminal neuralgia and hemifacial spasm are sometimes caused by a posterior fossa mass lesion. When these two disorders co-exist, a rare association known as ‘tic convulsif’, a lesion involving the fifth and seventh cranial nerves in the cerebellopontine angle is extremely likely. Twenty-eight cases of tic convulsif have been mentioned in the literature and two more case are reported here. They are of interest in that both cases many years elapsed between specialist opinion being first sought and the discovery of the underlying lesion.
三叉神经痛和半面痉挛有时都由后颅窝占位性病变引起。当这两种疾病共存时，一种罕见的关联即“抽搐性抽搐”就极有可能出现，这种病变涉及桥小脑角的第五和第七对脑神经。文献中提到过28例抽搐性抽搐病例，此处再报告两例。这两例之所以令人关注，是因为从首次寻求专家意见到发现潜在病变都相隔了许多年。
