Abstract

Anastomosing hemangioma (AH) is a rare and benign vascular neoplasm that is regarded as a morphological variant of capillary hemangioma. AH has been encountered primarily in the kidney. To our knowledge, para-aortic involvement of AH has not been reported previously. Here, we report a case of slowly progressing AH involving the left para-aortic region in a 72-year-old woman with a history of breast cancer surgery. A contrast-enhanced, dynamic abdominal CT scan revealed that the lesion had peripheral enhancement with slow centripetal fashion, which is an enhancement pattern similar to that of hepatic hemangioma.

  Fig. 1 Anastomosing hemangioma involving the para-aortic region in a 72-year-old woman. A-C. Contrast-enhanced dynamic CT images show a mass (arrows) measuring about 4 cm in the left para-aortic region. During the arterial phase (A), the mass shows peripheral enhancement. The mass shows slow progressive centripetal enhancement during the portal venous (B) and delayed phase (C) with central heterogeneous low density. D. The CT portion of a PET/CT image obtained three years before the present CT scan (Fig. 1) shows an oval mass (arrows) measuring about 2.7 cm in the left para-aortic region, which was missed on initial interpretation. The mass did not show FDG uptake on the PET image (not shown). E. Photomicrograph (H&E staining, × 200) of the para-aortic mass shows proliferation of irregular vascular channels lined by hobnail endothelial cells. Cellular atypia and mitosis are not noted. FDG = fluorodeoxyglucose, PET = positron emission tomography
