Acute abdomen caused by
spontaneous rupture of the inflammatory myofibroblastic
tumor of the urinary bladder (IMTUB) is a rare clinical emergency of the urinary system.It is difficult to distinguish it from
spontaneous rupture of bladder caused by other causes before surgery. An emergency case of
spontaneous rupture of IMTUB was reported. A 57-year-old middle-aged woman was admitted to the hospital because of "acute lower
abdominal pain for 5 hours". No history of smoking and gross
hematuria. The physical examination revealed visible abdominal tenderness as well as signs of
shock. A pelvic CT scan shows a space-occupying lesion above the bladder with massive accumulation of blood. When the nature of the
tumor could not be determined, emergency
laparotomy and
partial cystectomy were performed, and postoperative pathology confirmed
cystitis myofibroblastic
tumor. No local recurrence or distant
metastasis of the
tumor was observed during the regular follow-up period of 6 months. IMTUB should focus on prevention and treatment, with a combination of preoperative examination and postoperative pathology, and finally implement highly individualized treatment.
