Angiography reveals characteristic hypervascularity and irregular vessels in small bowel leiomyomas and leiomyosarcomas. These findings aid in diagnosing gastrointestinal bleeding from these rare tumors.

Area of Science:

  • Gastroenterology
  • Diagnostic Imaging
  • Vascular Radiology

Background:

  • Small bowel leiomyomas and leiomyosarcomas are rare tumors.
  • Gastrointestinal bleeding is a common presentation.
  • Accurate diagnosis is crucial for patient management.

Purpose of the Study:

  • To evaluate the angiographic features of small bowel leiomyomas and leiomyosarcomas.
  • To correlate imaging findings with clinical presentation of gastrointestinal bleeding.

Main Methods:

  • Retrospective analysis of selective mesenteric angiography.
  • Review of 22 patients with small bowel tumors (19 solitary leiomyomas, 1 multiple leiomyoma, 2 leiomyosarcomas).
  • All patients presented with gastrointestinal bleeding.

Main Results:

  • Tumoral hypervascularity and dense capillary staining were observed in all cases.
  • Prominent, irregular feeding arteries were seen in 19 patients.
  • Prominent draining veins were noted in 20 patients.
  • Contrast extravasation, indicating active bleeding, was identified in two patients.

Conclusions:

  • Selective mesenteric angiography demonstrates specific findings in small bowel leiomyomas and leiomyosarcomas.
  • Angiographic features include hypervascularity and prominent vascular abnormalities.
  • These findings are valuable for diagnosing the source of gastrointestinal bleeding.
