Acute urinary retention due to solitary fibrous tumor of the abdominal wall.

Solitary fibrous tumor (SFT) is a slow-growing neoplasm that affects both sexes equally but middle-aged patients more frequently. The course of the disease is unpredictable. SFT has been described in multiple locations. We present the case of a 62-year-old patient who went to the emergency room suffering from acute urinary retention due to solitary fibrous tumor of the abdominal wall. An arteriogram was performed with the decision make embolization before surgery. The SFT is a low-grade, potentially benign tumor. But the patient must be kept under strict oncological surveillance due to its uncertain behavior.
