Abstract

Thrombolytic treatment in the early stage of ischemic cerebral attacks requires rapid confirmation of the diagnosis and topographic localization. Unusual clinical features can lead to misdiagnosis with the risk of delaying optimal therapeutic management. We report the cases of two patients who experienced acute tetraparesis without any associated encephalic sign, consistent with the diagnosis of spinal cord injury. Cervical magnetic resonance imaging (MRI) was normal. Conversely, cerebral MRI displayed in both cases bilateral hemispheric infarction. Two ischemic lesions were revealed in the territory of both anterior cerebral arteries in the first patient, while the second patient had a bilateral infarction in the posterior arms of both internal capsules. In case of tetraparesis, emergency spinal cord MRI should be performed to rule out neurosurgical etiologies and ischemia. If negative, cerebral MRI should be performed at the same time to look for early cerebral infarction in both hemispheres and determine the indication for thrombolysis.
