RESUMEN
OBJECTIVES: The fibroma of mesocolon transverse is a rare lesion occurring primarily in age about 45-55 of years. The rarity of these lesions and the absence of characteristic clinical findings makes diagnosis difficult. STUDY DESIGN: The authors describe a case of fibroma mesocolon transverse in woman aged 75 years which became directed to Department of Gynecology & Obstetric in Hospital of Slupsk on account suspicions of ovarian tumor. RESULTS: Fibroma mesocolon transverse usually present as abdominal distention of long duration, pain, vomiting, less frequently as a palpable abdominal mass. Rarely they cause an acute abdominal surgical crisis clinically resembling appendicitis with peritonitis. Ultrasonography was the diagnostic method of choice. Other diagnostic modalities included intravenous pyelogram, barium enema examination, upper gastrointestinal tract series, CT scan and MRI in selected patients exclude gastrointestinal and genitourinary cysts and tumors. Histologically, several specific types could be distinguished of intra-abdominal lesions: lymphangioma, nonpancreatic pseudocyst, enteric duplication tumor, mesothelial tumor, enteric tumor, torsion of an omental segmental infarction cyst, hydatic omental cyst, omental fibromatosis tumor, ectopic ovarian cyst of the omentum, benign teratoma of the omentum or mesocolon. Treatment of choice of fibroma mesocolon transverse is always surgical (enucleation or resection of fibroma). Morbidity and mortality should be very low because of modern surgical techniques and follow-up procedures.
