We report the case of a patient with mesencephalic hematoma involving only the quadrigeminal plate. One case of superior and 3 cases of inferior colliculus hematoma have already been reported. Involvement of the quadrigeminal plate frequently follows a pontine or an anterior mesencephalic hemorrhage. The cause of these hematomas may be due to cryptic malformations of the quadrigeminal plate or primitive small size hemorrhages possibly related to the nature of the arterial system. Patients with inferior colliculus lesions present a typical symptomatology consisting of trochlear nerve palsy contralateral to the lesion or bilateral, contralateral hemiparesthesiae and acuphenes. Superior colliculus lesion causes upgaze palsy, visual blurring, dizziness and left upper lip paresthesiae. The cause of the different signs and symptoms in both types of lesion are discussed.
