Abstract
We present the clinical case of a 41-year-old woman with no relevant personal history.
The patient complained of diffuse self-limiting abdominal pain, and we incidentally
detected an extra-abdominal, extraperitoneal tumor mass at the level of the right
sciatic notch. The abdominal complaints were gone during the initial follow-up, but
the patient developed sciatica radiating to the right foot and electric shock-like
pain. A computed tomography (CT)-guided biopsy revealed a low-grade mesenchymal neoplasm
of the soft tissues with characteristics consistent with a solitary extrapleural fibrous
tumor. The pelvis team of the orthopedics department received the patient for surgical
excision of the lesion. The procedure occurred with no complications, and we excised
the totality of the lesion with tumor-free margins. An anatomopathological examination
was compatible with the biopsy assessment. The excision of the lesion resulted in
complete resolution of the sciatic nerve compression-related symptoms.
