Retroperitoneal Pelvic Solitary Fibrous Tumor With High Tracer Uptake in 68Ga-DOTATOC PET/CT

Abstract : We report the case of a 27-year-old woman referred to our department for the characterization of a 7 × 6-cm left ischio-anal fossa mass by Ga-DOTATOC PET/CT. Several diagnoses were previously mentioned, in particular, myxoid sarcoma but also pelvic paraganglioma. Urinary methoxylated derivates and blood chromogranin A tests were negative. PET/CT showed a high Ga-DOTATOC uptake of the mass that was strongly consistent with paraganglioma diagnosis. Histopathological analysis surprisingly revealed a solitary fibrous tumor without aggressive criteria.
