[Acute pulmonary edema secondary to a posterior fossa tumor: report of a case]. / Edema agudo de pulmão secundário a tumor de fossa posterior: registro de um caso.

A case of a 44-year-old woman presenting pulmonary edema secondary to posterior fossa meningioma is reported. The authors have tried to demonstrate the relationship between a lesion occupying space in the posterior fossa and important pulmonary abnormality such as interstitial edema based on increasing A-aDO2 (oxygen alveolar arterial gradient) in this peculiar case. A-aDO2 is easily measured and represents a good guide for evaluating the efficiency of medical and neurosurgical management when it is done in the serial way, particularly in those cases of non cardiogenic pulmonary edema.
