Abstract: : Objective To explore the reasons for misdiagnosis of paramedian pontine infarction. Methods 20 cases of paramedian pontine infarction which were misdiagnosed as cerebral hemisphere lesions were collected. The clinical manifestations, signs, and hyperacute cerebral CT scans, MR imaging characteristics within 48 h and other auxiliary examinations were analyzed retrospectively. Results 20 cases which were misdiagnosed as cerebral hemisphere lesions were confirmed as paramedian pontine infarction by MR. Conclusion Paramedian pontine infarction is rather common during daily clinical work, but often misdiagnosed. Early MR examination is helpful to correct diagnosis. For patients who have hemiplegic paralysis and transient dizzy symptoms during early phases, it is specially noticed that the lesions may be located in brain stem.
