University hospital.
Patient(S):
A 33-year-old Japanese woman complaining of right-sided sciatica.
Intervention(S):
Transgluteal computerized tomography (CT)-guided needle biopsy of a mass in the course of the right sciatic nerve was conducted for a histologic diagnosis.
Main Outcome Measure(S):
Histologic study with hematoxylin and eosin staining and CD10 immunohistochemical staining was performed.
Result(S):
Computerized tomography-guided biopsy was performed without any complication. CD10 staining distinguished endometrial stromal cells.
Conclusion(S):
Computerized tomography-guided biopsy followed by CD10 immunohistochemical staining is a minimally invasive procedure for accurate diagnosis of sciatic endometriosis.
