Mesenteric venous thrombosis in a pregnant woman at first trimester gestation: a case report.

Mesenteric vein thrombosis (MVT) in a pregnant patient is a rare condition that seems to be associated with the pregnancy pró-thrombotic state. This can lead to severe circumstances such as intestinal hemorrhagic ischemia, sepsis, abortion and death. Abdominal assessment is challenging due to the anatomical and physiological changes during pregnancy. MVT clinical and complementary evaluation are nonspecific, making essential an image exam. We report a case of a 33-years-old woman at 11 weeks of gestation. She sought medical evaluation due to abdominal pain and had an appendicitis diagnosis, which was treated by laparoscopic surgery. One week later, she came back complaining of nonspecific abdominal pain. So an extensive evaluation was made, and the diagnosis of MVT and intestinal ischemia was concluded. She underwent laparotomy exploration and anticoagulation, having a good evolution and so was discharged on the sixth post-operative day.

Pneumatosis cystoides intestinalis with pneumoperitoneum in an 87-years-old male patient: a case report.

Pneumatosis cystoides intestinalis (PCI) is a rare condition, characterized by gas-filled cysts in the intestinal wall. The mesentery and intra-abdominal ligaments can be affected. PCI is classified as primary or secondary and associated with multiple predisposing factors. An asymptomatic 87-year-old man underwent an abdominal tomography for follow-up of bladder carcinoma. The examination revealed intestinal and mesenteric pneumatosis associated with pneumoperitoneum. At laparoscopy, intestinal and mesenteric pneumatosis without intestinal infarction was identified. He was discharged on the fifth postoperative day. PCI is a benign condition that can be confused with mesenteric ischemia. Treatment is conservative, with periodic clinical evaluations. Surgical procedure is unnecessary for its diagnosis or management.

[Influenza B virus pneumonia after bone marrow transplantation: case report with emphasis to the high resolution computed tomography findings]. / Pneumonia pelo vírus influenza B pós-transplante de medula óssea: relato de caso com ênfase dos achados de tomografia computadorizada de alta resolução.

Nine year-old male patient, who underwent bone marrow transplantation because of acute myelogenous leukemia, presented with fever and dry cough three days after the procedure. The chest radiograph demonstrated bilateral diffuse reticular infiltrate. The high resolution computed tomography showed peribronchovascular interstitial thickening, peripheral small centrilobular nodules and areas of ground-glass attenuation. The bronchoalveolar lavage demonstrated positive direct fluorescence antibody testing against influenza B virus. Treatment with aerolizated ribavirin was instituted during 10 days and the patient showed clinical-radiological improvement.
