BackgroundLepidic predominant adenocarcinoma is characterized by frequent refractory hypoxemia due to intrapulmonary shunting. Severe hypoxemia can induce perioperative complications in case of thoracic surgery.Case presentationWe report a case of a 67 year-old woman with localized lepidic adenocarcinoma in the right lower lobe with severe hypoxemia. A selective arterial lung embolization allowed an instantaneous correction of the hypoxemia, and a curative lobectomy was safely performed 1 week after without any complication. The staging was pT3N0M0, and the patient received adjuvant chemotherapy.ConclusionsThis is the first case-report of successful endovascular embolization before curative surgery for a lepidic predominant lung adenocarcinoma.

Pedunculated hemangioma is a rare and atypical hepatic angioma. We report the case of a pedunculated hepatic hemangioma presenting as an abdominal sub-hepatic mass incidentally discovered in a 66-year-old woman with anal cancer. The diagnosis was strongly suggested by the vascular features of the lesion on spiral computed tomography (CT) and magnetic resonance (MR) imaging. A surgical removal of the mass was decided to prevent potential risk of ischemic volvulus along the pedicle. Histo-pathological examination confirmed this diagnosis. Contrast enhanced thin sections and subsequent multiplanar reconstructions on CT and MR are very helpful to show the angioma features and the pedicle linking the lesion with the liver.
