Learning objectives
Recognize the radiological signs by CT GIST’s angiography by discerning gastrointestinal bleeding.
Background
Topic Review
The gastrointestinal stromal tumour (GIST),
is the most common mesenchymal neoplasm into digestive tract,
but it represents less than 3% of gastrointestinal neoplasms.
It can occur in any part of the digestive tract and they are benign until an 80%.
Gastrointestinal stromal tumours are defined as single groups of mesenchymal neoplasms.
Most of the medical literature refers to these as smooth muscle tumours,
leiomyomas,
epithelioid leiomyosarcomas and leiomyoblastomas.
It is supposed that these tumors are originated at the smooth muscle layers in the...

Technical and radiographic features of gastrointestinal bleeding in GIST
Gastrointestinal stromal tumours (GIST) that affect the jejunum-ileum are a strange cause of lower gastrointestinal bleeding (2).
The diagnosis in the preoperative study is very important because of the difficulties presented while accessing endoscopically to the small intestine and sometimes surgical analysis are the last diagnostic and therapeutic option,
consequently in recent years,
advances in CT angiography plays an essential role when determining the cause of bleeding or spotting.
The technique of choice in patients with...
Conclusion
The CT angiography is the technique chosen for diagnosis of GIST with acute gastrointestinal bleeding.
It is important to recognize this pathology when a proper therapeutic management is used.
Because of last reason it is very important the radiologist would be familiar with this pathology and radiological findings,
for special attention to patients with active bleeding gastrointestinal.
