Radiologic imaging, including MRI, helps accurately diagnose and plan surgery for lymphangiomas, which are benign lymphatic malformations. MRI offers the clearest delineation of lesion extent, crucial for effective treatment and recurrence assessment.

Area of Science:

  • Radiology
  • Medical Imaging
  • Pediatric Surgery

Background:

  • Lymphangiomas are congenital lymphatic malformations.
  • Surgical extirpation is a curative treatment for lymphangiomas.
  • Accurate delineation of lesion extension is critical for surgical planning and assessing recurrence.

Purpose of the Study:

  • To evaluate the radiologic findings of lymphangiomas.
  • To determine the imaging appearance of these benign tumors.
  • To compare the effectiveness of different imaging modalities in delineating lesion extension.

Main Methods:

  • Retrospective review of radiologic findings in 18 patients with pathologically proven lymphangiomas.
  • Analysis of plain radiographs, barium meal studies, ultrasound, CT, and MR images.

  • Evaluation of imaging characteristics including mass displacement, cyst morphology, wall enhancement, fluid density, and signal intensity.

    • Main Results:

    • Plain radiography and barium studies showed masses displacing adjacent organs.
    • Ultrasound revealed uni- or multilocular cystic masses with variable wall characteristics.
    • CT and MR studies showed variable cyst wall enhancement; CT density varied with lipid content and hemorrhage. MR imaging provided clearer delineation of lesion extension compared to ultrasound and CT.

    Conclusions:

    • Ultrasound, CT, and MR imaging are valuable tools for evaluating lymphangiomas.
    • Magnetic resonance imaging (MRI) enables accurate determination of lymphangioma lesion extension.
    • Comprehensive radiologic assessment is essential for optimal pre-operative diagnosis and surgical planning of lymphangiomas.
