Pelvic plexus tumors are rare and often large at diagnosis. Surgical excision is the recommended treatment for these retroperitoneal lesions, with therapy tailored to the specific tumor type.

Area of Science:

  • Oncology
  • Neurosurgery
  • Pathology

Background:

  • Pelvic plexus tumors are uncommon and frequently present late due to non-specific symptoms and the retroperitoneal space.
  • These tumors can grow large before detection, complicating diagnosis and treatment.

Purpose of the Study:

  • To review the clinical characteristics and outcomes of patients with pelvic plexus tumors.
  • To analyze the types of pelvic plexus tumors and their association with neurofibromatosis Type 1 (NF1).

Main Methods:

  • Retrospective chart review of 44 patients with pelvic plexus tumors.
  • Inclusion criteria: minimum 12 months follow-up.
  • Evaluation of clinical presentation, imaging, preoperative assessments, and histopathological findings.

Main Results:

  • Peripheral neural sheath tumors constituted the majority (86%).
  • Histopathology revealed 18 solitary neurofibromas (41%), 12 NF1-associated neurofibromas (27%), and 8 schwannomas (18%).
  • Four non-neural sheath tumors (9%) included desmoid, ganglioma, lipoma, and a calcified mass.

Conclusions:

  • Surgical excision is the primary treatment for retroperitoneal pelvic plexus tumors.
  • Adjunctive therapies should be selected based on the specific histopathological diagnosis.
