AI Article Synopsis

  • Venous hemangiomas are rare tumors, and a case study is reported involving a 61-year-old woman with one located in the retroperitoneum.
  • Imaging techniques like sonography and CT scans showed a mass that adhered tightly to nearby organs and major blood vessels.
  • A subtotal resection was performed due to the complexity of the tumor, and follow-up MRI indicated a reduction in size and delayed enhancement of the remaining tumor, highlighting specific diagnostic signs.

Article Abstract

Venous hemangioma is an extremely uncommon tumor. We report a 61-year-old woman with a surgically proven venous hemangioma in the retroperitoneum. Image studies, including sonography, computed tomography and angiography, revealed a heterogeneous mass lesion with firm adherence to the adjacent organs and engulfing the major vessels. Only subtotal resection of the tumor was done due to technical difficulty. Follow-up magnetic resonance imaging 7 months after surgery showed reduction in size and much delayed enhancement of the residual tumor. In conclusion, firm attachment to adjacent organs and much delayed enhancement are clues for the diagnosis of a venous hemangioma.
