Postpartum transient blindness probably related to undiagnosed brain tumor.

Nausea and vomiting are so frequent under regional anesthesia during parturition that these symptoms can be misleading and may cause the clinician to overlook a potential intracranial lesion. In the case we have reported, it was not until the onset of blindness that an intracranial lesion was suspected. Although the incidence of brain tumor during pregnancy is low, it does occur with various manifestations and has been associated with blindness. Therefore, prompt neurologic investigation may be warranted in patients complaining of visual changes, even though transient blindness can occur in the absence of a neurologic lesion.
