Laparoscopically resected obturator nerve schwannoma: A case report

Area of Science:

• Oncology
• Neurology
• Surgical Oncology

Background:

• Schwannomas are nerve sheath tumors, with obturator nerve schwannomas being exceptionally rare.
• Preoperative diagnosis of obturator nerve schwannomas is challenging, with limited reported cases in medical literature.

Observation:

• A 68-year-old woman presented with abdominal pain, and imaging revealed a mass in the obturator fossa.
• CT and MRI demonstrated clear continuity of the mass with the obturator nerve, suggesting a schwannoma.

Findings:

• Histopathological examination confirmed a benign obturator nerve schwannoma.
• Laparoscopic tumor enucleation was successfully performed.
• Postoperative adductor muscle weakness resolved within six months with rehabilitation.

Implications:

• Accurate preoperative diagnosis of obturator nerve schwannoma is achievable through meticulous CT and MRI review, identifying nerve origin.
• Laparoscopic resection presents a favorable surgical approach for obturator nerve schwannomas.
• This case contributes to understanding the diagnostic and therapeutic strategies for rare nerve sheath tumors.
