Smoking active for about 20 years and using OC for 2 years. In view of the symptoms, she sought emergency services, where the first suspicion would be pancreatitis. Initial tests plagued leukocytosis. GUS of the total abdomen with doppler and CT of the abdomen showed the presence of thrombus in the right portal vein, with no other alterations. Rocefin® and metronidazole as an initial measure in the service began in addition to full coagulation with Clexane®. It showed clinical and laboratory improvement, with a reduction of leukocytes. The patient remained hospitalized in a hospital for 22 days to investigate the etiological cause. After of hospitalization, the patient was released with medical discharge, with guidelines for seeking the hematology service. During the investigation consultations, the results of the requested tests were negative for the diagnostic suspicions of nocturnal paroxysmal hemoglobinuria and chronic myeloproliferative disease.
