Retroperitoneal lymphangiomas present distinct imaging characteristics. Fine needle aspiration (FNA) confirms diagnosis, aiding in symptomatic lesion management.

Area of Science:

  • Radiology
  • Pathology
  • Surgical Oncology

Background:

  • Retroperitoneal lymphangiomas are rare congenital malformations.
  • They can present as symptomatic or asymptomatic masses.

Purpose of the Study:

  • To describe the imaging features of retroperitoneal lymphangioma.
  • To evaluate the role of fine needle aspiration (FNA) in diagnosis.

Main Methods:

  • Retrospective review of five retroperitoneal lymphangioma cases.
  • Analysis of ultrasound and computed tomography (CT) findings.
  • Cytological evaluation of fine needle aspiration (FNA) samples.

Main Results:

  • Lesions ranged from 4 to 15 cm, predominantly anechoic on ultrasound.

  • CT demonstrated water density masses with clear delineation.
  • FNA revealed characteristic cytology with abundant lymphocytes.

    • Conclusions:

    • Retroperitoneal lymphangioma exhibits characteristic imaging findings.
    • Ultrasound and CT aid in presumptive diagnosis.
    • FNA provides definitive cytological confirmation.
