A Rare Cause of Abdominal Pain; Celiac Truncus Aneurysm

Celiac trunk aneurysms are rare and constitute about 4% of all splanchnic aneurysms. Celiac trunk aneurysms usually occurs in the sixth decade. Although the most common reason is atherosclerosis, trauma, infection, tuberculosis or syphilis, fibromuscular dysplasia and polyarteritis nodosa may also causes this pathology. It is usually asymptomatic and detected incidentally. In symptomatic cases, the most common symptom is abdominal pain. The most important complications are rupture and thromboembolic events. Conventional diagnostic method is catheter angiography. With advances in imaging modalities, it can be easily diagnosed with a three-dimensional multidetector computed tomography. After successful surgery, mortality releated celiac trunk aneurysm decreases to 5%. It is recommended to be treated surgically which greater than 3 cm and fast-growing aneurysms. Eligible patients can be treated with endovascular interventional radiological methodsIn this case we presented a patient who were admitted to surgery department with complaints of abdominal pain and nausea. There were no pathological findings on physical examination, direct abdominal x-ray, chest radiograph and biochemical parameters. At proximal of the celiac trunk, it was shown approximately 3x2 cm in size fusiform aneurysmal dilatation on the patient%u2019s abdominal ultrasonography and turbulence, arterial flow on the patient%u2019s abdominal doppler ultrasonography subsequently. In abdominal computed tomography we detected dense calcifications, dilatation and hypodensities that may belong to a thrombus in the lumen superior mesenteric vein (SMV). At the same time, approximately 3.5 cm segment of trunk celiak we observed aneurysm dilatation which reaching 2 cm at the widest point. Celiac trunk aneurysm is a rare cause of abdominal pain and often noticed after the complicated, thus it must always be kept in mind in the differential diagnosis
