Abstract:
A gastrointestinal stromal tumortumour (GIST) is an
uncommon gastrointestinal neoplasm that can arise
from any part of the gastrointestinal tract. They can
rarely present as a pelvic mass, which might result in
a gynaecological condition being misdiagnosed in a
female patient. A woman in her early 70s presented with
a huge pelvic mass. Abdomen-pelvis CT scan showed
a significant cystic mass in the left-sided pelvis with a
mass effect on adjacent structures, which suggested a
possibility of an ovarian cystadenoma. Her CA-125 was
normal. She underwent an exploratory laparotomy with
pelvic mass excision. A diagnosis of a gastrointestinal
stromal tumour (GIST) arising from the ileum was made
on a histopathology study
