Rapid Growth of a Giant Intra-Abdominal Desmoid Tumor Diagnosed During Pregnancy

Summary

We present a case of a 32-year-old woman who had been diagnosed with an intra-abdominal mass during fetal assessment ultrasound performed at 25 weeks of gestation. Considering characteristics of the mass, the first diagnostic presumption was that of 2 fibroids. At 31 weeks of gestation she was admitted to the hospital with complaints of shortness of breath, abdominal pressure and difficulties to lie on a back. On examination a significant growth of the intra-abdominal mass with signs of necrosis was observed. Following this, due to worsening mother state and a vast increase of inflammatory markers, planned Caesarean section at 32 weeks of gestation was performed. Following the delivery of a live neonate intraoperative evaluation of intra-abdominal mass by multidisciplinary team of surgeons was performed, no connection with uterus and adnexa were observed and decision was made not to intervene. After performing postoperative computed tomography scan gastrointestinal stromal tumour was suspected, inflammatory markers continued to grow and was decided to resect a tumour. However, postoperative histological examination revealed an intra-abdominal desmoid tumour.
