Abstract

Facial palsy is a condition frequently encountered in neurological daily practice. Typically, telling apart peripheral facial palsy (PFP) from central facial palsy is easy, and depends on the presence of the upper face involvement. However weakness of eye closure can be seen also in cases of central facial palsies, making the diagnosis more difficult. When the facial involvement is isolated, that constitutes a crucial diagnosis challenge because it can be misdiagnosed as Bell's palsy, particularly in young patients. However, subtle clinical findings such as a predominant involvement of the lower face and the presence of a dissociation of emotional and volitional facial movements points towards a central etiology as in our patient. We report here a case of isolated peripheral-type facial palsy due to acute bleeding of supratentorial cavernoma. To our knowledge, such case has not yet been reported.
