Abstract: | A 28-yr-old man presented with recurrent reduced consciousness, generalized seizures of unknown etiology, recurrent hypoglycemia, psychomotor retardation, and grade 2 ectasia of the left kidney. Abdominal computed tomography (CT) and positron emission tomography (PET) scans demonstrated a well-circumscribed suprapubic pelvic mass, measuring 18 x 15 x 11 cm, with involvement of para-aortic lymph nodes and dilatation of the left ureter suggestive of an extragonadal testicular tumor. We excised the tumor by laparotomy, and it was confirmed to be a solitary fibrous tumor (SFT). After surgery and R0 tumor resection, the patient had no further evidence of hypoglycemia or of recurrence. |
