Description

Aggressive abdominal wall fibromatosis is an uncommon tumour that has propensity for significant growth. Patients often present during pregnancy, with growth related to the associated hormonal changes having been described.1 In the majority of patients the condition can be managed conservatively, as regression on completion of the pregnancy may often occur. While surgery  in pregnancy is to be avoided where possible, we present a case whereby rapid tumour growth, severe pain and breathlessness due to the large tumour mandated urgent surgery. In cases such as this, after failed conservative management, any surgical treatment  must ensure safety of the mother and the fetus, complete tumour excision and subsequent abdominal wall reconstruction. The images in figure 1 depict the coronal section of an MRI scan performed during the second trimester (left), the wide dissection required to ensure complete tumour excision (top right) and the resulting abdominal wall reconstruction (bottom right). The patient delivered a healthy boy 4 months after surgery by elective caesarean section.
